I just fixed this problem on my neighbor TV. I don't have a manual or schematic, and didn't pay any attention to the reference designators, so I will just have to describe it. The problem was a bad solder joint. Visible thermal fatigue. Looking at the main board, (didn't even need to slide the cassis out). There is a small, narrow, vertical board in the center, adjacent to the yoke connectors with a funny looking little transformer on the very top. Check the connections on that.

My apex gb5108 projection tv did the same thing but I had a blue line accross the middle. I had two problems with mine. One, the tv repairman fixed. A vertical something had to be replaced. This did not cost a lot. But the blue screen is my problem now. I can turn on my tv and I get sound and a blue screen. But if I leave it on a few minutes (like it has to warm up) then turn it off and right back on....then the picture comes back? You may have a very inexpensive problem with yours, if you can find a repairman to look at it.
