Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.
But need to measure the connection SC2, if it short, it will be the SC board.
The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!
