10 blinks can be a host of problems with the television. Something has failed and tripped the SOS detect circuit (causing the 10 blinks).

You would have to take this thing apart and trace down voltages from the P, A, D, SC, SS boards to determine what could cause it. Hell, even the memory card reader on the front can cause a 10 blink error.

You will want to see a professional.

Usually seven blinks indicates a Y sustain problem. Its either the Y sustain pcb and/or the buffer boards. I would highly recommend calling an authorized service center for this if you don't know what you are doing.

SOURCE: Panasonic TH-42PX60U plasma TV: red blinking light

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

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 the same problem Panasonic Plasma TV wont come.


Alot of times capacitors on the power supply circuit board will go bad. They will bulge/dome or dry up which will cause this problem. Bad caps dont hold a charge, which is needed to maintain a voltage. The circuit board is two sided which makes replacing the caps difficult, and the board can be damaged and have to be replaced. Taking it to a repair shop may be cheeper and safer then doing it yourself. Having two-six caps replaced is a lot cheeper then a new board.

TH-42PX60U red light blinks 10 times wont come on


On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.
