Summary: Purchased 4 years ago and it did great up till recently. Once it dimmed down and started having the issues I contacted Panasonic who said they'd look at it if I shipped it to them (my cost) then paid $130 to diagnose. I checked their website and found a local repair shop. That shop basically said it's a great unit when it works, but there are three main issues with it, and that it sounds like I have one of those issues...
Summary: Personal Experience Purchased late 2007, installed in a smoke free dedicated cinema room from the ceiling and never removed untill problems developed in March 2011. Great unit up until time to replace the first bulb, then MAJOR problems Problems AT 1980 hours the unit began shutting off by its self after 3 min of running. I checked the web, found the advice for the iris, did the lube job, no help.
Summary: Personal Experience This projector has two serious problems. One is that the iris grease hardens up and the projector fails after 300 hours or so. They probably fixed that in later models. You have to open it up and take a q-tip and dab some Super-Lube on the iris and that seems to fix it. Second is that many people have flicker problems, myself included. Panasonic claims that it is not a known problem but it is certainly a known problem online.
Summary: I bought this projector in early 2007 and it was awesome for the last three and a half years. Just this week it started turning off after 30 seconds of being on. I replaced the bulb thinking that would help, but it didn't. The on button goes red and won't respond to trying to be turned on. If I unplug it, I can turn it on again ....for another 30 seconds before it does the same thing again and shuts down.
Summary: Personal Experience Image was very good and controls were fine. Unfortunately it encountered shutoff problem that many others are having. Huge hassle having to send off for repair and about a $300 bill. Panasonic should be offering repair at no cost. Problems 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.
Summary: Personal Experience I was quite happy with the quality and features of the unit until it suddenly started shutting down and the iris started doing odd things. As you have probably read in other reviews this apparently was a manufacturing defect by Panasonic. Quite disappointed not only that this occurred, but also that they would not cover the repair costs.
Aside from the common iris problem plague, good projector

Summary: I'm not going to go into full detail about the features and picture quality, etc., you can do that research elsewhere. I just want to point out to people that, yes, while so many of these projectors experience the oh-too-common iris problem, it is fixable. I fixed mine and my projector is working fine again. Here is the link to the page I used to solve my problem and to where I posted my experience (ptatohed). Good luck! [...
Summary: Personal Experience I have had this projector for about 2 years of which 18 months it has not been working/working properly. Had a the IRIS problem and had to fight with Panasonic to get them to fix it. Very poor support. Finally got it fixed and got prism block, yellow spot that continually gets larger. Costs more to fix than replace. So...I replaced it with an Epson 720. Much happier now.
