SOURCE: TH-42PZ80U Panasonic Plasma, red light flashes 10 times

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.

In an earlier review I gave this product 1 star. Not because of its performance, but because I couldn't understand how to use it. The web site looked nice but was hard to follow. I really wanted it to work for me, but finally gave up. I really wanted this device to work for me, and now it does fitness tracker reviews

Sony Trinitron won't turn on red light blinks 9 times


Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not re-solder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative).
