Bad capacitors...! Remove rear panel cover from tv. Most require a star screwdriver. Look for bulging caps in power supply board. (3300uf 10v ) caps need to be replaced with 3300uf 16v. Identify the bad caps.... Caps are bad when they are bulged/bulged and raised. A good Cap is flat X top not raised or buldged. I have pics of what bad caps look like on these boards. Email me if you would like to to see them. Caps cost abywhere from 1-2 dollars or you can buy them in lots of 10 or 12 on ebay for around 8 bucks. Caps need to be soldered on. Do it yourself (if confortable) or take it to a tech/pc repair shop in your local area. Do do that unplug all the wire harness from the board and unscrew the boarda nd take to your teck to solder on the new caps.

You can fix this for about 20 bucks if you have someone else solder or 40 cents if you buy the caps on ebay and replace the 2 bad ones yourself. If one is bad and the other is not replace them both.

The caps go bad because they need to be a higher voltage. 10 insn't enough..... 16 is plenty and don't go any higher than that.


Good Luck

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.

Panasonic TH-42PD50U RED ON LIGHT BLINKS BUT WON'T STAY ON


Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.


2
. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.


3. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.
