SOURCE: Panny TH-42PZ80U Plasma TV No display on Power-up

I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!

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.

My last question was in reguards to a panasonic th-50px 75u I have small black vertical lines all across the screen and a rainbow effect on the picture all channels and all inputs


Press the menu button on the TV remote and see if the lines are on top of the menu or covered up by the menu. If the lines are covered up by the menu, the issue is being caused by your source device.

Turn on the TV, red light stays on, picture goes blank after a second.


I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

I have a Panasonic 46" flat screen plasma tv that will stay on for as long as you want, but when turned off, will not come back on for hours


If the set is a few years old you might want to look at the caps in the power supply--not unusual for them to be puffed up and hence cause issues like this.
