Summary: I was reading a lot of reviews and people have been complaining about the IRIS isuue and short bulb life. I have had the IRIS issue as well, I think it started around 1200 hours of use. The projector would shut down after a few min.
Summary: I found out about an issue with this projector but was pleased to find there are ways to fix it on the internet and you don't need to have an electronics background to fix it. The IRIS problem reared its ugly head and WD40, some Qtips and a little bit of patience fixed the issue.
Summary: Personal Experience My projector has started failing with a known issue with the Iris after 990 hours of excellent viewing. Panasonic don't want to replace a defective part FOC, instead want $350 ; this does not seem fair.
P-sonic extended the warranty by 6mos. Also, AX200U solves iris issue

Summary: Highly recommended for color, clarity, flexibility, and ease of use. Panasonic has extended the warranty on this model by 6 months (total of 1.5 years). Also, the PT-AX200U solves the iris problem if you want to buy that unit without the warranty hassle.
Summary: I've had the Panasonic for over a year now and I have 1,100 hours on the Lamp. It's only turned itself off once that I know of in the last year and I didn't think anything about it at the time.
Summary: Personal Experience IF YOU ARE EXPERIENCING SHUTDOWN PROBLEMS, see my link below: http://avsforum.com/avs-vb/showthread.php?p=12816058#post12816058 Unbeatable price performer when it was new, very bright, good contrast and good image. Using with a 2.35:1 150" screen.
Summary: Personal Experience I purchased this projector in Jan 2007 and by and large it has performed very well. I use it a lot (TV and movies) and I'm very satisfied with the picture. However, like so many others, I ran into the evil IRIS ISSUE at about 1000hrs.
Summary: Personal Experience Love the image, but reliability is poor. Went through 3 projectors. First had color uniformity issues. Fixed with later models? 2nd and 3rd units had dreaded IRIS failure with less than 400 hours on lamp. Fortunately, bought from the big C store. Just got the ax200.
Summary: Excellent projector... when working. At 500 hours I had the infamous "IRIS" problem. After 2-3 min the projector would shut down. It is now at Heartland in Kansas for warranty repair. Despite this inconvenience, for the price, the performance is superb.
