Question about Sony KDF-E42A10 42 in. LCD Television
This problem occurs often but not always but the background will initially get dark and then it will go to greens or reds
Typical problems with lcds.. When they get hot, the color tends to shift. The reason your seeing the problem on the red and green is because of a lack of blue.. Makes sence if you think about it as blue is the hottest wave of light, so the blue panal is getting too hot or possibly the polarizing filter on the tv..
Lamps can cause this somtimes as they tend to shift twords the higher waves at the end of there life.. So if you have another lamp, try it out.
Another possible cause is the driver board for the lcds.. If there is a chip that has a small short, it will overheat as well and cause it not to function properly. I see this all the time on lcd projectors. 1 of 3 things.
