I have a TH-42PZ80U Panasonic Plasma TV, when I turn it on, the red light flashes 10 times then it will stop. Then after a few seconds it will flash 10 times again then it will stop, this will go on and on... don't know what to do.
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.
@TVhelp-Dave. I'm having the same problem with the same TV. Is the A board the main input/ output board? Where did you get the repair manual that you site in your response? I'm decent with electronics, but it is impossible for me to walk throught these steps without a schematic. Do you know where to find a copy of a manual like this in physical or pdf form? Thanks a lot. Your responses are always thorough and usually right on the money. I appreciate any help I can get.
Sorry, Iam notable to post the schematic.

Most likely the problem is in the power supply and most of the time can be fixed by replacing a few capacitors but, you may want someone professional to do them to make sure you don't make any short circuit.
Take to a service agent 10 is usally error code for power board
