Need Power Supply Schematics:
I hoping that someone on the forum will provide me a more detail repair manual, because the service manual i have on hand doesn't provide me with enough information to make a repair on the power supply.
Below is the service manual in reference to what i am reviewing. I hoping to troubleshoot for a fix.
Thanks Guys!

I need good clear straight shot of the top and the bottom side of the power supply board, and also the pictures of the whole backside of the TV showing all the boards.

So the main AC fuse is good for sure?
If it is then you need to measure the DCV between the two legs of the MAIN filter caps (there are four of them connected in parallel which are under the heatsink, it should have about 160VDC between the + & - legs). You have to take the board out and flip the board over to get to the cap's legs, I would plug the AC cord into GFCI outlet to protect yourself.
