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.

I have a Panasonic TH-50PE700U


I think if you Google research the model with "10 blinks" you will likely find it is bad power supply or related to it.

I plug in my TH-42PZ80U and it doesnt turn on but a red light blinks ten times.


Apparently this common problem is due to a faulty power board. Contact Panasonic for a replacement if it's under warranty (hopefully) or a local repair shop. Good luck!

Tv wont turn on< red power light just keeps blinking?


I have the same thing. Just started blinking 10 times. Pretty much had to unplug the unit over night. Could never turn it off and then turn it on again.
This worked for about a week. This morning, tried to turn it on after being unplugged. Still blinks.
Called Panasonic. they attempted a couple solutions, nothing. Suggested authorized repair shop.
