Summary: We've had this projector since 2007 and it now has almost 940 hours on the lamp. We have had no problems with the projector. It was purchased on a military installation in northern Japan and survived the move to the US and a second move in the US.
Summary: I bought this projector back in 2006 and it has been a great projector. I am on my third bulb and every bulb lasted righ at about 3000 hours. The screen I have is 180" and the picture is great. The only problem I have had with it is just like several people described.
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.
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...
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.
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.
