I've determined that the main board is bad, TV is dead with 5V standby going to main board.
I have been unable to find the exact replacement for the last couple months, so I thought I'd just check some voltages on the main board.
I do have a very similar working main board that is for a different panel, so I was able to compare voltages.
Basically on the original board, I have 5V in and 3.3V out as seen on the regulator in the last photo, but nothing really else.
The other board has readings at the other regulators in the area. But I'm having trouble tracing where it's breaking down..
In my hand written mess anything in ()'s is the working board.
Any help would be appreciated! Thanks.
