    I have exactly the same issue. If I unplug\replug the TV I can get it to turn on for a 3-5 seconds, then it just turns off and starts blinking the power light.

    I tried to turn my television on this morning, and all that happens is that the red power light starts blinking. I unplugged it for several minutes, but when plugged back in it still blinks.

    A recent thunderstorm caused? the loss of several digital channels received through antenna. The tv was turned off at the time, but on turning it on, only PBS channels remain.

I had the same issue twice with a TH 42PWD5. turns out it was my UPS that was killing the switching power supply. Warranty covered it but when I removed the UPS not a single issue in 3 years.

The power supply board of the television is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem....

When the Panasonic TH-50PX60U is turned on, the button beside the power switch flashes 10 times, stops and repeats the flashing. The tv will not actually turn on.

10 times red light blinking shows problem with PA board and/or H board, both boards are available in for $35 and $45
Replace required board to solve this issue.
Hope this info will help you.

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.
