ok so… there is a kill switch relay on the powerboard,almost the first component in the circuit. it will look like a small black or /blue , somtimes yellow rectangular box. it wiill have 6-8 pins soldering it too board.
almost every time. i fix a tv that does it. of coarse. whatever diode down the line burned out allow and is allowing high volt spikes when relays flip. is still burned out thus thee relay coil will also burn out eventually. unless u add a high efficent diode between switch outlet and and un switched oulet pole. poles ——->--arrow facing toward switched. this will atlt least protect from the “main” high voltage spike.
they do make relays with diode built in. but i like to build my own relays. so they work forever….. also use a heatsink between solder connection and diode or u will pop it. (make it not have direction). well love,hugs, and happy mucking.

Also when I power on the TV, a light flashes across the screen then goes black. With just a really faint tint of picture or menu on the screen. Can only be seen when you're holding a flash light up to the screen. Sound works perfectly to what ever input you select.

I don't know if this is the reason but I suffer from the same problem but I believe that the TV isn't getting enough power from the cable you plug into the outlet
I Feel That's The Problem
