I just purchase this model from a reputable distributor and it arrive this evening . Hooray ! I set it up in the same ceiling location that we old dlp projector be located . after read the manual and tweaking the setting , I sit down to watch a movie . I must say the picture be a great improvement over we old projector . however , 20 minute into the movie , the screen turn into green and black vertical stripe and slowly fade to red . the unit be unresponsive . I could not even turn it off . I try call the distributor technical assistance line but to no avail . then I try to call Panasonic . they automate answering system would have be comical if I be not so tick off . it tell you to speak naturally and then connect you to the commercial sale division or anywhere but technical assistance . ultimately , I have to turn the main power switch off at the rear of the projector . I know that that action be a `` no-no '' since the fan should keep run to cool the bulb , but I do not want to leave it on until somebody from some technical service department call I back at some future date . I would like to be tell you how great this projector be , but there it sit , on my ceiling , like a dead , dark , lifeless , $ slightly below msrp yet still expensive $ box . I try to turn it on again , but it just flash some red on the screen and turn off , like some piss off -lrb- albeit , die -rrb- HAL 9000 . I will be send this unit back tomorrow and will not be ask for a replacement . I will probably try a Sony or BenQ for the next one . Panasonic have they chance and they blow it , errr ... blow up . if you want to try this projector , just make sure you can return it or have it repair locally . the picture do look really nice for about 20 minute .
