Panasonic PT-AX100U

Evan Powell, September 26, 2006

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.

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.

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.

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.....

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.

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.

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.

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?

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.

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.

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.

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.

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!!!!!

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.

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.

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.

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.

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.

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 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.

"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.

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.

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.

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.

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?

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.

"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."

"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.

"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.

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!

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.

"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.

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.

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?

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?

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.

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..

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,

Alistair G.

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?

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!

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 :)

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.
