    I'll just say this. I've asked this same question many times and never got a perfect answer. From what i've gathered though it is certainly possible that pixels can go out over time. It's not likely that it will happen to much but over years i'm sure you'd lose a few. Whether or not you'll even be able to notice them from a normal viewing distance is another story.


    On another note, I just returned my 42" GW III and got a 34" Sony XBR910. The fan on my GW III was getting louder and I was told that was the warning sign of a light bulb problem. I basically just got scared of the new technologies and I don't want a DLP or LCD Projection until they've perfected them. At this point I don't think that is the case. If you can deal with having a 34" screen I can assure you the XBR910 will give you video quality that is as good as you can find right now. Clearly better than the GW III.


    I just can't recommend either a DLP or LCD right now but if you absolutely have to buy one of them i'd go with the LCD Projection. It's a more stable technolgy than the DLP and i've heard Sony has fixed the light bulb issue on the GW III's they are now making. That may be true but it wasn't enough to quell my fears and i'm happier now. I lost 8 inches of screen size but I gained a lot in image quality.

    There are 3 million pixels ... yes they can die as surely as tiles fall off the shuttle.

    I just recieved a new Panasonic PTL-300U LCD projector. There's a dead or stuck pixel (blue) just off center. Not really noticeable on light scenes but very distracting on any dark scene.

    Are there ways to fix this? Thanks for any input. [​IMG]

    Only way to fix this is to replace the lcd panel. Not covered by warranty except in extreme cases.

    Fact of life with fixed panel displays.

    Thanks Michael. That's what I figured. I've read where others have had the pj replaced if the pixel is centered.

    The repair is at the discretion of the TV maker ... so it cannot hurt to ask some times ...

    The worst that could happen is that they say no ...

    Regards
