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. -John
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.

This television, appears to have had a failure in the mainboard. This
is the board that controls the video functions and sound functions. The
unit should be taken or sent in to a service center for testing and
servicing. The service center will have all the correct service
information to determine the problem for you. You can call Insignia

the support section and ask them for help on how to get service for
your television. I hope this information helps you with your problem.
I have one that the picture is not working properly on. It makes kind of a u shape rainbow across the center of the screen. If my husband is willing to part with it, i'd like to sell it. where are you located? you can contact me by email, [email protected]
When I turn on my TV
it goes straight to the menu screen. You can still hear sound but no
picture. When I try to exit you see the picture for about a second then
it automatically flashes back to the menu screen. Even if I try to use
the functions in the menu screen it flashes right back to the main menu
screen. Very frustrated...need help!
