The Panasonic PT-AX100U is the seventh model in a line of low-cost widescreen LCD home theater projector to come from Panasonic's laboratories in under five years. Starting with the original AE100, an 854x484 projector released in January, 2002, the Panasonic home theater projector line has progressed through increasingly higher resolution, higher contrast, and ever-improving video processing capabilities. Models have included the AE200, the AE300, the AE500, the AE700, and last year's AE900. The AX100U is the latest and by far the best in the line.

One could argue that this is the single most influential line of digital home theater projectors ever brought to market. It features unique innovations such as Panasonic's "Smoothscreen" technology that completely eliminates visible pixelation. Moreover, with the AE700 we saw the first combination of horizontal and vertical lens shift along with a 2.0x zoom range which allowed for previously unknown installation flexibility. With its aggressive pricing strategies, Panasonic has hastened the erosion of competitive DLP 720p pricing and brought high quality, large scale home theater within the financial reach of the average consumer.

Overview

The AX100U is a much improved version of last year's AE900. It retains the long 2.0x zoom range which enables it to deliver a 100" image from a throw distance of anywhere between 10 and 20 feet. The primary benefit of this long zoom range is that it enables the user to place the projector on a rear shelf, and get a wide range of projected image sizes no matter the depth of the room. This will allow most users to avoid the cost and nuisance of ceiling mounting the projector. In addition, the AX100U has manual horizontal and vertical lens shift. When the lens is in its neutral position, the centerline of the lens intersects the image just above its geometric center. Once again, this design is optically ideal for a rear shelf mount.

However, if you wish to ceiling mount, you can shift the lens such that, once the projector is inverted, the top edge of the image is below the centerline by about 16% of the picture height. So for example, if you are projecting a 120" diagonal image, the picture height will be 59", and the maximum gap between the top of the image and the centerline will be 9.4". In practical terms, after adding a few vertical inches for the ceiling mount itself, if you have an 8 foot ceiling, the 120" image will appear on the wall about where you want it. If you are going for a smaller image, say 100" diagonal, or if you have a much higher ceiling, the range of the lens shift will not be able to compensate for such a radical offset. In these cases, you may wish to use an extension tube with the mount to keep the image from appearing too high on the wall. (We don't recommend tilting and using keystone correction on any 720p projector since it causes all signals, and native HD 720p in particular, to be rescaled.)

One of the unique features of the AX100U is its "Light Harmonizer." This gives the projector the ability to detect and automatically recalibrate itself to varying ambient light conditions. In total darkness it will reduce its lumen output and maximize black level. But when someone turns a light on, it will automatically boost lumen output to brighten the picture and make it easier to see.

The Light Harmonizer can be set on AUTO mode, or it can be either deactivated or set to manual mode. Thus, in the event you don't care for the results of the automatic adjustments in Auto mode, you can adjust the projector to output the level of brightness you want. Manual mode enables you to set the iris at one of ten different apertures of increasing brightness.

Another capability that is new to many of the latest home theater projectors is the ability to accept and display a 1080p/24 signal. The AX100U will accept 1080p/24 as well as the more conventional 1080p/60. The 1080p/24 format is important because it will become a standard feature on many of the new high definition DVD players, HD-DVD and Blu-ray. Indeed, a couple of the Blu-ray players scheduled for release next month already have it.

The benefit of 1080p/24 transmission between the HD player and the projector is that it eliminates the need for 24 frame/sec film material to go through 2:3 pulldown conversion. This conversion has always been necessary to get film to synch with the 60 cycle displays that are part of the NTSC world. But with digital projectors being able to run at 24 Hz (or multiples thereof, 48 or 72 Hz), the conversion to 60 Hz is no longer needed. This will eliminate occasional artifacts such as judder in slow panning sequences and allow a smoother display of the film source. Once we acquire one of the new Blu-ray players with 1080p/24 output, we will do more testing to assess the degree to which this feature actually contributes to any incremental improvement in the viewing experience.

The AX100U offers a lot of flexibility in setting it up for various sources and lighting conditions. Not only will it save separate configurations for each input, but it offers three universal "favorites" which can be saved and loaded to any input at any time.

Finally, the AX100U comes with an all new remote control that is much easier to use than previous models. It is backlit, and the buttons are large, well-spaced, and easy to read in the dark. The remote provides button control for input selection, aspect ratio adjustment, picture adjustment, color management, access to precalibrated settings for dark theater viewing, living room viewing, favorite calibrations, as well as access to and control of the full menu. Most remote controls are a source of frustration for one reason or another. This one is not.

Performance

The AX100U delivers the most elegant and natural video image we have yet seen from LCD technology. By comparison, last year's AE900 was an incremental step beyond the formidable AE700, but this year the AX100U represents a very significant step to a whole new level of performance. Black levels are noticeably improved, and the subtle softness that we found in the AE900 is entirely gone. The AX100U's image is extremely sharp and clean.

Deinterlacing was already extremely good on the AE900, and it continues to be so on the AX100U. We find no difference in performance between the two in this regard. However, scaling on the AX100U is significantly improved and the image is quite obviously rendered with greater precision than its predecessor. The AX100 is able to resolve standard definition resolution test patterns to near perfection, whereas the AE900 was not quite there. There is also noticeably less digital noise and better color saturation and openness in the midtone values on the AX100U when it is placed side by side with the AE900. Collectively, these improvements produce a much refined image that, to say it again for emphasis, looks both elegant and natural.

The range of lumen output on the AX100U is exceptional. In optimized dark theater mode, our test unit measured 343 ANSI lumens. But in Vivid Cinema mode, which still retains exceptional color and contrast, brightness was boosted to over 800 lumens. And in Dynamic mode we were able to get over 1400 lumens without too much compromise in image quality. This would be ideal for a Super Bowl party where brightness in ambient light is all important, and small variances from color standards are not noticed by anyone. None of Panasonic's prior models in this line have anywhere near this range of lumen output flexibility. (The AX100U will actually generate lumen outputs higher than 1400, but we wouldn't use those settings for video viewing or gaming.)

Panasonic's SmoothScreen technology eliminates any hint of pixelation, even at very close viewing distances. Historically, LCD technology has tended to manifest more visible pixel structure than DLP products of the same resolution. But here the situation is reversed. Every DLP 720p projector we have seen in our lab thus far has more noticeable pixel structure than does the AX100U.

The Light Harmonizer feature is interesting, but it does not provide the full range of automatic adjustments to ambient light that the projector is capable of if you adjust it manually. For example, if it is operating in the low lumen Cinema 1 mode in a dark room, the introduction of ambient light will cause the projector to automatically boost lumen output by about 15%. However, if you go into the menu and select the Vivid Cinema mode, light output more than doubles. In addition, if you are already in Vivid Cinema mode, the Light Harmonizer does not have any incremental effect on light output. Therefore, the feature nicely accommodates a limited amount of ambient light introduced into a dark room, but it is not comprehensive enough to manage the projector's light output for all ambient light conditions.

As far as fan noise is concerned, there isn't much to worry about. Even in its brightest operating modes, the AX100U's fan noise remains remarkably quiet. There won't be any users of this projector opting to run in lower lumen output modes in order to reduce fan noise.

Conclusion

The Panasonic AX100U is the closest thing to a truly universal home theater projector we have yet seen. Its 2.0x zoom range and lens shift capabilities make it easy to place almost anywhere in the room you might want it. And its exceptional lumen output range will allow you to use it in a wide variety of room sizes and ambient light conditions. If you have a very large room, say 30 feet in depth, you may want a larger screen to go with it. You can install a 150" diagonal screen, and still put the projector on a rear shelf. That can save you time, effort, and the cost of a ceiling mount and long run video cables. Meanwhile, the Vivid Cinema setting will allow you to fill a 150" screen with a rich, pixel-free image. On the other hand, if you have a smaller room, you have the option to run in one of the low power Cinema modes that are ideal for a 100" screen in a dark room.

Though the versatility of the AX100U is one of its most distinctive characteristics, the ultimate satisfaction with this projector comes from its sharp, natural film-like image. In particular, standard definition DVDs look better than we've ever seen on any 1280x720p projector within this price range.

We rarely rate any projector a full 5 stars across the board, but the simple fact is that we find nothing to complain about with the AX100U. Panasonic has combined outstanding image quality with unparalleled ease of use and versatility in a way that we've not seen before. And as of this writing it is all available for street prices under $2,000. Accordingly, we are happy to give the PT-AX100U our strongest recommendation.

My biggest problem with each of my two Panny purchases is that when watching a black and white movie, such as "Ed Wood", there is a subtle color shift from one side of the screen to the other. The left would have a cool zone, while the right would have a warm zone. It was so bad, I had to take it in for repair (no easy feat) and when I got it back, it was reduced, but now there is a slight offset in calibration of the convergence. I gave up.

I long for the day that we see a 4 panel LCD where you have Red, Green, Blue, and Gray. This would improve contrast ratings even more!

I currently have the PT-AE700U, and frankly, I was miffed when my lamp went out after only 1,000 hours!! So I think I am going to wait for a while and see if this is a problem with this new version. After all, once I buy one, I'm stuck.
SaveOnProjectors Posted Nov 5, 2006 3:32 PM PST
I think having 1 less input then a PT-AE900U is a major oversite by Panasonic. I can't find a reason for not having it, especially if the previous model had it. Also, PT-AX100U is larger then PT-AE900U, so people upgrading, and having installed 900 on the shelf, might have to get a bigger one :)
GMW360 Posted Dec 2, 2006 8:20 AM PST
Well, after checking reviews all over the net I was about to buy the -PT-AE900U then I read the reviews for the AX100U. I was sold. I searched many stores for a demo of this new projector in action but found none. There are fewer stores that show demos these days. To make it worse the few demos I saw didn't look good at all. It appears they were improperly set up. I saw Sony's new 1080p projector in one store, which looked good but my old Sharp DLP 800X600 pixel projector showed a better picture. My guess is they had it running a normal DVD through a composite cable, whereas I use a component cable for my setup. Cable lengths probably also added to their picture issue.

To say the least I was unimpressed. If I did not already own a projector and know what image quality it was capable of I would have not proceeded further, if a USD10,000 sony 1080p projector looked that unimpressive, you would think to stick to LCD or plasma TVs! If I had spent all that money on a demo room I would have a HD or Blu ray player and HDMI at the very least.

To cut a long story short I bought the AX100U and from initial start up was very impressed. I haven't even yet connected it properly and tested it with an HDMI cable and HD-DVD or Blu ray yet the picture off DVD was amazing and bright like the LCD TVs you see on display in Best Buy. Wow!

I'll write a longer report once I've put some more hours on it. Before I forget, it looks smaller in the pictures than in real life, but not too big, manageable. The sony 100W? is BIG!
In the Market Posted Dec 4, 2006 11:44 AM PST
We recently purchased a Panasonic PT-AX100U. Fantastic picture and easy to set up and use. However, we are having one slight problem.

When we watch cable television, we sometimes get a white, shimmering/pixilation effect across the top 1-2% of the screen. The effect appears to be limited to broadcasts in 4:3 aspect, but, is not specific to one station or broadcast type. For example, the H-D, 16:9 broadcasts are perfect. However, certain H-D, 4:3 broadcasts exhibit the effect. Specifically, while we watched a Harry Potter movie with no issues on HBO HD (16:9), the effect was seen while watching "The Wire" on HBO HD (4:3). Similarly, while we watched a football game on ABC's local station in analog (4:3) with no issues, when the local news broadcast came on the same station right after the game (also 4:3), the effect appeared. Again, the only common denominator is 4:3 aspect, but only for certain broadcasts.

In regard to connections, we have our Scientific Atlantic 8300 HD-DVR cable box hooked to our Denon 4806-CI AV receiver using HDMI. In turn, the receiver also is hooked to the projector with HDMI. Any thoughts on what is causing this effect and how to eliminate it?
Live_Steam_Mad Posted Dec 17, 2006 2:01 PM PST
This sounds like an issue due to Overscan ? On my Infocus IN72 projector I can crop the image by 3 per cent or zoom into the image by 3 per cent, to remove these overscan issues, or I can display the overscan area in full. It's the "overscan" button on my IN72 remote control.

Hope this helps. Just a guess.

Cheers,

Hey..

Just wanted to hear, has any of you heard of problems with ghosting when it comes to connecting Xbox 360 to AX100?

Any of you heard of any kind of trouble with Xbox and AX???

Regards..
txmrlevine Posted Mar 20, 2007 7:54 AM PST
I love my 900 but could not move up to the AX100 because it does not have the second component input. That is a big mess up by Panny - why would they take functionality away. Maybe they should have added another HDMI input. I do not have the ability to run HDMI to the projector so that is a moot point for me but might have helped someone. I think they are expecting you to run your Cable box / DVD player and any other inputs through some type controller to get the signal back to the projector. I like running my projection directly from the source without going through a controller. I will do that for sound but not video.
yaip Posted Apr 28, 2007 7:22 PM PST
I am shopping for projectors. For my needs, AX100 seems to be perfect. Since the projector is going to be in my family room, a projector that works well in ambient light is a must. I can't close the blinds and make the room dark all day.

However, I just want to make sure that there is nothing better available out there. Any suggestions?
gadgetfriend Posted May 14, 2007 10:22 PM PST
Can this model, Panasonic PT-AX100U, be used as a mobile projector as well? Is the focal length suitable for projection in a room for 100 persons?

Driftwood Posted May 29, 2007 7:13 PM PST
I found it several places using Google for $1200 or so new, not a refurbished. I know the prices were falling, but that fast? I get it this week. I'll let you know if there are problems.
Driftwood Posted May 30, 2007 2:01 PM PST
I posted too soon. It was a scam. I ordered online and was emailed and told to call to confirm the order. When I did they tried to sell me a warranty for $399 ( Google shows many offering the same at $129) and when I didn't bite, I was told I needed to buy a lamp, the unit didn't come with one. I had their web page for the AX100U in front of me, and asked where it said there was no lamp. The response? He actually said "Where does it say it DOES come with a lamp?".

A variation of this fraud happened with Broadway Photo, Regal Camera, Digital Liquidators and Prestige Camera. All in NYC, all unethical, lying thieves. They could all be the same store, I wouldn't doubt it. I have no problem if they want to advertise the fact that is doesn't come with a lamp, but there is no way to know this from ordering on line. Each of the sites offers suggested accessories, yet not one is suggesting a lamp.

I strongly suggest everyone avoid these 'dealers'.

I discoverd the connection to all these bait and switch artists by checking the Better Busniess Bureau Online (http://search.bbb.org/searchform.aspx). I use it all the time to check out companies I haven't done business with. Very helpful.
Driftwood Posted Jun 2, 2007 8:21 PM PST
That would have helped. Also ResellerRatings.com is good too. 5 seconds there and I would have seen what thieves they are. They are the kind of thieves that make you lose faith in people. They know they are frauds and they just don't care.
h0st Posted Aug 26, 2007 4:39 AM PST
I'm afraid there's a mistake in the review of the Panasonic PT-AX100U.

Review says: "However, if you wish to ceiling mount, you can shift the lens such that, once the projector is inverted, the top edge of the image is below the centerline by about 16% of the picture height."

It can mislead you since the maximum vertical shift is 63% from the image height and not 16%. Max. horizontal shift is 25%. When combined, the range will be lower. Since this information is crucial when making calculations of the home cinema installation, I'd suggest the authors to correct the article.

Thank you!

h0st Posted Aug 26, 2007 7:22 AM PST
Hmm.... it seems I'm though wrong and must appologize, since the shift is from the centre of the screen (as stated in Panasonic's manual).

So now I'm confused. According to the manual, if we shift the projector vertically up by 63% from the centre of the screen, won't the calculation mean the lens will be lower than the top edge?

I'm planning the set-up and got totally confused now...

Thanks in advance for your help!

If your screen is 50" tall, then you multiply 50 by .63 which gives you (about) 31.5"

You can move the projector (center of lens) about 31.5" above the CENTER of the screen. This puts the centerline of the lens about 6.5" above the top edge of the projected image. Closer to 13% instead of 16%.

Since my screen is 106" diagonal it could be a bit over 6.5" above the top edge of the screen. This, of course, goes with the concept that there is no horizontal lens shift in use which will bring down the vertical lens shift range.
CarScott Posted Sep 11, 2007 1:23 PM PST
"whats the lowest price for this pj?"

As of Sept 2007 Projector People had it for $1299 after rebate. This also included a Sanus ceiling mount. It can be had for about $100 less other places but, as described in other posts, they may not be trusted sources. I've purchased from ProjectorPeople.com in the past and have had great outcome each time. Yes, you pay $100 more but the peace of mind must be worth it to work with a reputable and knowledgeable dealer.
yaip Posted Sep 11, 2007 2:01 PM PST
My PT AX100U has been working fine and I am very impressed with it. Till now. It has been around 3 month since I ceiling mounted it. It has been working fine. Since last week, it has started behaving strangely. Every morning, when I turn it on with my remote, it turns itself off after a few minutes. And it stops responding to the remote. Even the Power button on top of the projector doesn't work. It only works after I use the on/off switch behind the projector. And it happens only once a day. The first thing in the morning. The rest of the day, the projector works fine and responds to the remote fine. But the next morning, the same problem. It is like if I let it rest for more than a few hours, it stops responding.

So I called Panasonic. They say that it is a faulty piece. And I've to ship it to Kansas. So now I've to dismount the projector from the ceiling and ship it. Meanwhile, I can't watch any TV.

I have this exact same problem. My PT-AX100U PTAX100U goes black or goes blank and turns off after a few minutes, you kill the main power, wait 10 seconds, turn the main power off, press the power button, and it works... happens once a day. Totally bizarre.

Surdyman Posted Feb 7, 2008 4:30 AM PST
I am so thoroughly disillusioned with Panasonic! I have the same issue but only after 120 hours of usage! The first time I start the Projector it shuts of after 5-6 mins and then NO button works! I have to manually restart the machine. I called Panasonic and they said that it needs to be sent to Kansas (i'm in Bangalore, India). I heard somewhere that even after fixing this, the problem can reoccur? Is that true? Does ANYone have any gems of wisdom to offer?
Oragustus Posted Feb 26, 2008 9:31 AM PST
I also had the Iris problem (the grease lubricant was drying up and the Iris mechanism would get stuck.) I sent it off to Heartland (the Panasonic Repair facility) and had it back and running a week later. The early replacements had the same problem, but all replacements are now getting the Iris mechanism from the PT-AX200 model. The difference is that the new model uses a ball-bearing mechanism which doesn't get stuck.
STEPHEN Posted Sep 29, 2008 3:02 PM PST
I LOVE MY PROJECTOR, BUT WHEN I TRY TO HOOK UP THE HDMI CABLE UP TO IT. IT WON'T WORK. CAN I GET SOME HELP PLEASE!!!!!!!!
Brett Posted Oct 22, 2008 1:04 PM PST
To all who purchased this projector, shutting down after 5 minutes is a known and fixable issue. If its out of warranty you can do the fix yourself. You can either replace the iris (which will require the manual, you can find that online for about $12), or get some household 3in1 oil, remove the bulb, the iris is on the other side of the light prism.. you can they put a few drops of oil onto the iris bearing (pivot point). You can see what I mean by trying to move the iris arms, its where the upper arm attaches and pivots. After putting a few drops of oil on go ahead and move the iris arms a few times, then let it sit overnight upside down (this allows a drop to move down to the lower iris arm). after the overnight check the arm again if its moving free you should be set. otherwise go to panasonic online parts and order the iris, its $85 and its from the newer AX200u, and get the manual, its involved but doable by anyone with some pc-repair experience.. cheers!

Paul Posted Feb 2, 2009 7:39 PM PST
I've had my Panasonic PT-AX100U projector for just over 2 years, love it, but now at 2025 hours - and bulb replacement is required... have not seen and picture deterioration at this point, what would happen if you just reset the lamp timer... ?
Chris Posted Feb 4, 2009 10:31 AM PST
I have a problem with the aspect ratio control. There are preset options to choose from, but it doesn't let you adjust the aspect ratio manually. Does anyone know how to do it? If you watch something downloaded online it only shows it with a 1.85:1 ratio - even if it's supposed to be 2.35:1. This makes it so the screen is squished and everyone looks all long and skinny. I messed with the Over Scan button, but it has a very limited span and didn't help at all.
Joseph Kutryk Posted Feb 4, 2009 3:49 PM PST
I hate this piece of ****. I have had nothing but problems. Panasonic does not give a ****. They knew there was an Iris problem but had no qualms about charging me $2800.00. now its two years later and all I've got is an oversized paperweight. I HATE PANASONIC!!
Jospeh Kutryk Posted Feb 5, 2009 4:03 PM PST
My projector had an Iris problem but it finally stopped working altogether. I have 1300 hrs on it and this is the second time its been in the shop, although for a different reason. After contacting the right people in Panasonic, they will now ship and repair it under warranty even though my warranty ran out. I'm happy now but it might be up to five weeks without my PJ. Sorry for the language in the last post, I didn't know that word was offensive.

Who at panasonic did you speak with? I just started having the same problem with the Iris and I am positive my unit is out of warranty(build date Feb 2007). I am hoping they will fix it for free.

Thanks!

DONT buy this projector. We bought 4 for our training centres and EVERY ONE of them developed the same fault after 4 or 500 hours. They keep switching off. Panasonic dont appear to give a damn... I say this after a week on the phone to them complaining. just my 2 cents worth
Cris Posted Apr 11, 2009 11:59 PM PST
"To all who purchased this projector, shutting down after 5 minutes is a known and fixable issue. If its out of warranty you can do the fix yourself. You can either replace the iris (which will require the manual, you can find that online for about $12), or get some household 3in1 oil, remove the bulb, the iris is on the other side of the light prism.. you can they put a few drops of oil onto the iris bearing (pivot point). You can see what I mean by trying to move the iris arms, its where the upper arm attaches and pivots. After putting a few drops of oil on go ahead and move the iris arms a few times, then let it sit overnight upside down (this allows a drop to move down to the lower iris arm). after the overnight check the arm again if its moving free you should be set. otherwise go to panasonic online parts and order the iris, its $85 and its from the newer AX200u, and get the manual, its involved but doable by anyone with some pc-repair experience.. cheers!"

Brett or anyone else that knows,

I have this iris issue also and was planning on replacing the iris with the iris from the AX200U model since it is a ball bearing iris. But, when I go to the Panasonic website under the AX200U parts, I can not find this iris that you are talking about for around $85. Does iris go by another name? I tried to search and find out but was not successful.

Could it be this... TXZEC03VKD3 OPTICAL CINEMA FILTER 84.60

Thanks.

I am disappointed with Panasonic Projectors. As many have noted, I too have the shut down problem regarding the iris on the AX100-U, which is obviously a product wide problem. Additionally, I had a 700 that its bulb burned out at 600 hours, and various websites noted that this was a known problem with the the 700. In both cases, Panasonic did nothing proactive, i.e. recall or recall notice, even though both were obviously product defects. While the picture on the units is great, the integrity of the Panasonic projector division is less than expected and disappointing. Think twice before buying Panasonic.

I have had my projector 1.5yrs. Shutting down and doing the reset.Sounds like a common problem.I was told it was a problem with the A board and it needed to be replaced....at a cost of $800. NOT...i wont put that much into a piece of #@*@ panasonic. FOR SALE CHEAP anyone interested,lol.

I hope this is somewhat useful - I'm at work and don't have time to read through all previous posts. I notice some talk about the shutdown/reset issue. I encountered this about 25 months and 1,900 lamp hours into my ownership of the PT-AX100U . I called a very nice gentleman at Heartland who quoted me a few hundred bucks just to diagnose the issue. Instead, I tried the q-tip fix and immediately fixed the issue. I removed the entire top casing of the projector (although I believe the iris may be more easily accessed through the trap door on the bottom?), sprayed some WD40 onto a q-tip, and rubbed it against the hinge of the iris (two maroonish plastic pieces). I haven't had a problem with it since!

I'm a big fan of this projector. I'm considering selling it only because I'm looking at picking up a 1080P unit.

I'll never buy another panasonic product. This [expletive deleted] piece of [censored] has been to repair depots twice, once through Panny sent to some 3rd party repair shop, came back with blue smudge in the right corner of the image and it lasted about 3 months, then the same BS shutdowns. I had to literally fight with Mack Camera to service it, same prooblem identifed, IRIS. It took them 3 months and they tried to charge me, serivce charge of 200 bucks and 60 shipping, I didnt pay any after complaining.

Its still [edited] (not working properly), same problem, I have to start it half a dozen times before it stays on, unplug, then it stays on.

This is a very lightly used projector, under 800 hours. If it acts up much more I will post a youtube video of me bashing it to bits with a baseball bat.

[expletive deleted]Panasonic, this should have been a class acton lawsuit.
Hiram Bertoch Posted Nov 18, 2009 11:59 AM PST
thank you. very helpful. Took ten minutes, and saved me bundles of money. Not to mention my presentation.
Phil H. Posted Dec 21, 2009 2:00 AM PST
I have been without my beloved PT-AX100u for many months now. It would run for a minute or so then go to standby and then you couldn't turn it on again unless you turned off the master switch. I finally decided that I was going to buy a replacement as a family Christmas present. For some reason I decided to look up the projector one more time because I remember a lot of people complaining about the same problem as I had. I remember some people were able to get Panasonic to fix the problem, and I thought to my self, maybe I'll give it one more try. Thankfully I did not have to thanks to a post by Mike D. Applying WD-40 to the Iris Hinges was a simple enough thing to try, and I figured, what do I have to loose. Lo and behold, it worked awesomely. I could tell the difference immediatelywhen I applied the WD-40, the stiff movementdissapeared and the Iris immediately sprung back when I moved it by hand. All I can say is thank you Mike D.
Marley Posted Jan 23, 2010 8:30 PM PST
Machine started shutting off and I had to reset main power switch at the back. At first one or two resets did the trick and it would stay on. Finally it got to a point where numerous resets didn't work. Going through Panasonic (Heartland), they are charging $276.26 to replace the iris. Judging from the numerous complaints, Panasonic ought to recall and make the repair at no cost. Very disappointed.
sohail Posted Mar 12, 2010 8:20 PM PST
I bought panasonic pt-ax100u 2 years back but for the past 3 months or so started having the shutoff problem. I was reading some IRIS issues, can someone tell me what is IRIS and where can I find it. can I use WD40 to fix the problem. thanks
Michael Posted Aug 9, 2010 2:05 PM PST
Buyer beware, I have had mine for about 2 years now and have had multiple issues. the dynamic iris problem which cost me a couple hundred to fix and now the blue lcd panel is going out which costs 3-4 hundred. this model is also infamous for burning polarizer screens which costs 100 bucks for parts. Needless to say, im a bit sour on Panasonic these days, im sure if you continue to read comments you will see im not the only one.
Jack Brannelly Posted Sep 27, 2010 3:35 PM PST
What is the best deal on a replacement lamp for the PTAX100U? Do I need to buy one with the casing, or can I install the bare lamp?
Cooper Posted Nov 8, 2010 7:26 AM PST
Stay away from this [expletive deleted] company. Projector is awesome when it works, but it obviously has a design defect that Panasonic refuses to "man up" for.

Have had mine for about three years. Iris problem reared it's ugly head about 1 month after the initial warranty period was over. Kept resetting the power not knowing any better, until that failed to resolve a start up. Lamp light was blinking, but the picture looked normal when it did work so I hesitantly shelled out a few hundred bucks for a new lamp, which did not fix the problem. Since it was out of warranty, I took it to a local electronics repair place who charged me $380.00 to repair/replace the IRIS with a 90 day warranty. I swear, about 92 days later, same issue. I was pretty calm about it at first, sometimes you get a lemon and things sometimes just break, but this one was starting to get in my craw because I had almost $700.00 bucks trying to fix something that only cost me $999.00 to begin with and it's still broke.

Long story short, go through the whole process of finding out about the cheap lubricating fix, which temporarily fixes the problem. It worked at first on about a 6 to 8 week interval between "lube jobs" but now it's a weekly occurrence of getting the thing down off the ceiling mount and screwing with it just to get it to work like it should.

Panasonic is making a huge mistake by screwing there loyal customers on this. Panasonic CS is about as helpful as [negative phrase deleted]. I have over $12k of Panasonic products in my home and office between Plasma TV's, LCD TV's, phones, BD & DVD players,shavers etc.. No more. Panny has gotten the absolute last penny they will ever get out of this customer and has in fact created a negative megaphone who will warn anybody not to buy products marketed by this company. I fully anticipate a class action law suite against them on this issue. As a matter of fact, I'm thinking about actively investing the time and effort to see what it will take to get one started.
Greg Field Posted Dec 26, 2010 2:00 PM PST
You can take Panasonic to small claims court. I had a bulb issue and they refused warranty coverage because I failed to mail in the card. Bullshit. So I sued and they had a traveling lawyer who appears in court on their behalf, and if you stick to your guns about your claim and insist that the judge is likely to assess your credibility along with your documentation you will win. You should sue for the entertainment and enjoyment time you lost, come up with a nice fat figure in case they want to negotiate it down. I got the full amount I asked as to the value of the bulb, $300, I had the check 2 days later. Now GO GET EM!!!!!
Rob Posted Jan 23, 2011 10:09 AM PST
We have had this projector for over five years and over 6000hrs of use - we are on our 3rd lamp. It is used as our main TV in our family room. We have been very happy with it, it has been great. A few months after we got it, we did have the iris problem which was fixed for no charge.
Jassy Posted May 19, 2011 8:31 AM PST
Did anyone know how to or which IC I should change for English Language, Mine is only display Japanese. Model PT-AX100U. Thanks
Cwas Posted Jan 12, 2012 7:21 PM PST
When you take the bottom panel off the bottom you can see what the problem piece is. There is a small piece that almost looks gold on the one corner of the lamp. If you take a screw driver push on it and it will turn, when you let go of it the plastic piece should snap back very fast if it doesn't WD40 will work. Put it on the end of a Q-tip and put it around the center rod that holds the gold plastic piece and work it back and forth until it moves very fast and your so called iris problem is fixed.

Need help!!!! My pt-ax100u all of a sudden lost its hdmi connection! I plug in hdmi cable and it doesn't even see it connected. The other connections work fine though Has anyone experienced this? Is there a reboot or a default I can program to get it back?
Jonathan Posted Aug 1, 2012 8:15 PM PST
My Panasonic AX100 has started to shutdown after 2 hours of use, i believe it is overheating.

I thought It was the Iris problem (it was indeed stuck), so I applied that fix (WD40) but the projector still shutdown and the temp light came on.

Has anyone else experienced this and know the solution?

I checked the Service Menu and Temp 1 drifts down (overheats), while Temp 2 stays around 165. What is the standard reading for Temp 1 during normal operation?

The front air exhaust is where I feel blazing heat, the one besides the lens, while the projector is running you can see there is a fan inside. Is this supposed to turn in normal operation? Mine doesn't ever.

I called Panasonic tech support and they suggested I plug it in a new outlet and if that doesn't work I would have to mail it in for $130 (non refundable diagnostic, but applicable to repair cost) + shipping.

Have any idea what is happening with my projector?

I'm trying to determine if it is hopefully fixable or time to buy a new projector.
Vikram Sharma Posted Aug 14, 2012 12:07 AM PST
Hi, just read you comment for the Panasonic AX100U. I have the same model & had experience the IRIS problem, which seems to be okay now. The overheating may happen occasionally (since i stay in north India, where the temperatures tend to soar as high as 48 degrees C in peak summer), this may happen due to outside/room temerature abnormally high or else, the filters are locked and not clean. the same problem occurred with my set this summers, i cleaned the filter & it worked fine (only after a few days though). Also do you have an AC in the room where you have installed your projector? Guess it help to maintain cooler temperatures.
Bruce Posted Sep 28, 2012 9:38 AM PST
I have over 3000 hours on the original bulb, is there any danger to postponing the replacement until the bulb fails completely? I watch in a very dark room, and haven't noticed any loss of light yet.... Could the bulb eventually burst and cause a real problem? Or will it just go dark at the worst possible moment?
jcr Posted Oct 3, 2012 11:35 AM PST
I have ran my projector lamp upwards of 5k hours. @ around 3 k the projector will start displaying the " replace lamp" message. I have great insurance on the projector that would cover me in case anything happened to the unit, so I decided to experiment and see what would happen if I didn't change the bulb. all I did was reset the lap run time on the main menu.

after 5k + the lamp was still working fine, no loss of brightness. BUT football season was starting and I typically have people over. I didn't want the lamp to stop working mid game so I just gave in and replaced it.
Vin Posted Nov 9, 2012 5:29 AM PST
I ran my AX100 past the Lamp replace message, just reseting the counter. After about 4000-5000 hours though the picture started getting very dim until eventually the lamp basically exploded. Nice. Just replaced the bulb and everything's soooo much bighter.
HillbillyBob Posted Dec 25, 2012 1:34 PM PST
Anyone having a problem with the projector turning off after a few minutes, read all the comments below this one. There are excellent instructions for fixing the problem at zero cost. There is also a YouTube video called "How to fix projector PT AX100 E" that shows how to fix it. Thank you to everyone for posting this information! Hate the garbage on the internet, but love when people help each other out with stuff like this. Too bad Panasonic won't step up and solve this problem.
Clif Dodson Posted Dec 30, 2013 7:36 AM PST
I have had my panasonic ptau100-x projector for 3-4 years. It started the shutoff thing after 1 month. applied wd 40 and worked fine until now. Shuts off every 10 minutes even when I am applying wd 40 every 10 minutes. This thing cost me a fortune in money but more in time.....
william Posted Jan 24, 2014 7:19 AM PST
Ho do you replace the lamp;is there a door to open?I have the housing with new bulb. Thanks, bill
Mica Posted Feb 10, 2014 11:06 AM PST
Try checking your lamp hours. After 2000 hours the projector will go in to standby after 10 minutes of use. Reset hours to "0" and it should be okay, if that was the issue, until the lamp actually burns out. Have a spare handy.
Ryan Posted Jun 10, 2014 10:47 AM PST
I bought my PT-AX100u in 2007. After over a year of use it developed the iris problem. Panasonic was willing to repair it outside of warranty. I thought I might have problems again in 2011--auto shut-off--before learning it was just the automatic bulb-life reset at 2,000 hours. I reset the meter and all went back to normal. I replaced the first bulb in 2014 after over 4,500 hours of use thinking it was dimming a bit. I definitely saw an improvement with the new bulb but the old bulb wasn't horrible. Seven years on, this has become one of the best electronics purchases I've ever made. I keep an eye on bulb prices for fear of a shortage. I hope to get several more years out of this unit.

The auto-white feature has meant no complaints against white/yellow/grey walls without the need for a dedicated screen--something I haven't had the pleasure of using for several years now. The 2x lens has also allowed for massive images in small spaces. The lens' flexibility has allowed for lots of creative placements, in a pinch, with minimal aberration/blur at the edges.

The iris issue led to fears of regret in Year Two. But seven years in, it's an old friend.
Robert Posted Feb 1, 2015 5:41 PM PST
Has this projector the ability to project 3D, I have had my projector a number of yearsa nd it has not given any trouble and has excellent light and visual quality, my DVD player needs replacing and I was going to buy Blu Ray 3D can this projector be used with 3D or Blu Ray only. Any recomendations where to buy a spare bulb
Thomas D Posted Dec 26, 2015 10:26 AM PST
I guess I got lucky since I hadn't bought one of the very first models/or it was different for me since I bought it in Germany (E-Version). From what I read, they replaced the iris on later models after the serial problems had emerged.

So I've had the Panasonic PT-AX100E projector for like around 7-8 years I think and have used it approx. 5000h (I am on my second bulb now). Have not had a single complain. Runs like a charme. So I got my moneys worth out out of it and hope to have it live through a third bulb. Wish more consumer tech was that well built.

3 tips: When buying a lamp, best order it from Panasonic in Japan. They are expensive, but it's the real deal and not some cheap copy which doesn't last long enough. (No, I am not from Panasonic; I just read some reviews online of people who had gone for a third party solution and were pretty disappointed because the lamp exploded/stopped working after 500 hours.)

Also the eco mode will cause the lamp to flicker after so many hundred hours. Make sure to use it at least every so often with the regular mode so the residues inside the lamp can be burned off properly (or whatever exactly the physics of that is). You will notice the flickering best on purely white backgrounds (desktop), not so much in games/movies. The lamp flickers and sometimes "gets stuck" in a dimmer setting. That is because the light arc is not properly jumping.

Oh and also as mentioned every so often: After approx. 3000h in eco mode the projector will automatically turn off after 10 minutes to prevent lamp failure. The projector does take into account whether it was used in eco or regular mode, so this may happen sooner than 3000h. (This is not stated in the manual, unfortunately.) So you can reset the lamp time. How long the lamp lives after 3000 hours is anybody's guess, but it may eventually explore when the glass becomes to strained by all the heat.

[...] select "Lamp Runtime" Press and hold the Enter button for approximately 3 seconds The "Lamp Runtime" will change to "Time Reset [Power Off]" Turn off the power and disconnect the power cord

Those were the most important three things for me not covered in the manual, when you want to use the projector for a long time.
mica Posted Sep 10, 2021 3:15 PM PST
Well here it is in 2021. Don't know if anyone still reads these inputs, but this projector has been simply outstanding. I purchased this projector in .. I believe... 2008 or 9. I have reset the blub timer many times and I am still using the the original blub that came with the projector(new)!! I keep waiting for it to burn out, but the little guy just keeps going. The whole unit has provided me with hours and hours of "movie room" relaxing moments. Even, what? twelve years on, this projector is the BEST. Love watching football, movies and other video presentations. If it does ever break, I think I might go find another one... hopefully in excellent condition! Any way, it's a great projector for those looking to set up a movie room. I have NEVER had any issues and I have gotten my monies worth out of this buy.
