Testing my Panosonic TC-P50S2 SC Board Help Please...

TV powers on for a second then off…with the 10 blink code.

Have replaced the A Main board with known good. Still 10 blink code.

Unplug the SS board results in same 10 blink code.

Unplug the SC board results in now a 7 blink code.

Have tested the buffer boards SC & SU…..A OK.

Would like proper detailed testing for the SC board please.

SC Board is TNPA5105AB.

Have watched 100 YouTube videos…None on this specific board.

Thanks in advance.

PS: My TV is not the Viera…Just was only option in the drop downs for “Choose a Device”
