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.

The power supply probably has failed. The clicks indicate it is trying to start up but can't.

Panasonic plasma tv doesn't turn on, red light flickers twice


hi look for any swollen capacitors, also plasma's do suffer from poor solder joints on the power board, so check for any rings around the solder pads, test the voltages on the white connectors with a meter the voltages will be written along the connector,thanks

Following a audible pop TH 50PZ85U will not power on.


Most common thing to happen is a capacitor went bad on one of the circuit boards making the loud POP sound. Odds are it's on the Power Supply Board if the TV isn't showing power at all. The picture below what a bad capacitor looks like.

They range from different sizes and color. Swollen, deformed, and raised top is the thing to look for.

Solder in a new capacitor on the board or replace the whole circuit board.

I had the same problem with my new TH-50PX60B. I turned the tele on then after 5seconds it would switch off. The standby light would then blink on and off 11 times, pause for a second then flash 11 times. This would continue until the power wasturned off. Note the TV would not turn on for more than 5 seconds.
I solved this problem by turning the tele on and checking the fans at the back. My tele had 3 fans. If one of the fans is not turning, this will be the cause of the problem and the tele will shut down under the Emergency Shutdown System. To clear the fan try blowing on it to free up any dust etc. If that still doesn't work try using a thin instrument (tie wrap etc) to manually turn the fan and free it. Then power off the tele and turn it back on. The tv should work perfectly.
