Hello everyone, posting this question in this owner's thread since it hasn't gotten any response in the general forum. I will be eternally grateful if someone can help me
My TV turns on and I can hear the sound, but the picture doesn't work. I only see a plain white image on the left half of the screen (the right half is completely black, see attachment). Note that the brightness of the white light seems to vary with what is supposed to be displayed (as the scene changes brightness, so does the light on the TV), so I think that indicates that something about the picture is making it to the screen.
I tried HDMI, VGA and component inputs, and the behavior is the same for all of them: I hear the sound but I don't see the picture.
I tried to press the TV menu button but nothing is displayed. I also tried going into the service menu but I don't know if that works, and I can't hear the chime (is that normal? I think I had it disabled in the TV menu prior to this problem, but I seem to recall the chime playing when entering the service menu).
I tried the AV out from the back of the TV, and that works fine: I can see the picture from what I'm inputting into the composite jacks.
When I say the left half of the screen is white, it's usually pure white. Sometimes, though, when I turn the TV on there are a couple dozen black pixels. The positiong and number of the pixels changes every time I turn the TV off and on.
Any ideas? My thought is it's a bad DMD board (the mirrors are stuck?), but I can't find a replacement part (BP94-02230A). But could it be a bad digital board instead? Or something else?
Any help would be really appreciated!
P.S. This is happening after the disaster described in the thread @ http://www.avsforum.com/avs-vb/showthread.php?t=1359615
. I managed to make some progress by replacing my Analog board and Detect board, before that the TV wouldn't turn on at all.
