10 flashing lights and no power; What is the problem and can I fix it?

I have the Panasonic 42inch TH-42PD5OU and I bought it 2 years ago. The TV shut down yesterday and is not coming back to life. It has 10 FLASHING LIGHTS next to the power button. I called a repair store and they said it most likely was a problem with the power supply and needed to be replaced for 800.00-900.00 dollars. What is the 10 flashing lights indicate? Can I order the needed part on my own? Can I replace the part on my own? I have read that these TV's are notorious for having this issue, please help. Thanks You Eric

    I do not know what the DT board is or how to access it. Where can I find information (i.e. from you or a repair manual) on how to correctly disconnect this part.

Hello, there is a problem with DT board. In order to pinpoint the error please disconnect the DT board. If the set powers up (starts-up) with the DT board disconnected please replace the DT board. If you need more info please advice. Arpi

Panasonic th-50pz800u shuts down and i can not turn back on, red light flashing 2 times, sometimes 10 times

Good day!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

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.

New 42inch plasma turned off while watching, can't turn on

Panasonic requires an authorization number first from them. Our parts suppliers require that before we can even order the part. I recommend calling a svc co. to have it looked at, preferably an authorized panasonic service center, it will be much faster.

Panasonic th-50pz80 10 flashing blinking red lights

The way to solve the problem with the TH-50PZ80U blinking light problem is to not buy Panasonic Products. I have had my TV about 21 months and it has started with the blinking light problem, just out of warranty. Panasonic is aware of this problem and refuses to do recall or fix the tv unless you are within the warranty or have bought the extended warranty. Legally they are within their rights, but I am also within my rights to air my complaint and inform others of this below par product. Who wants a TV that they have to unplug for a while and pug it in again for it to work. I want to push the power button and it come's on. I will never purchase another PANASONIC PRODUCT.
