Re: 3 year old element 40 inch tv, no back light

pictures now on first post

This tv flickered for a few weeks and then no picture. sound is ok.
I google search and found someone else with same trouble.
They said they had 81 volts on the cvb4200 power supply board.
I checked mine and had the same thing.
I got a new cvb42001 board from shop jimmy.
I checked its 4 outputs to (i think, the backlight) and was 25 vdc.
so
I installed the board and still no picture. sound was ok
I rechecked the 4 outputs to (i think the back light) and is now 81 volts.

i don't see any bad caps and nothing smells like a toasted...
