Th-42PZ80U 10 blinks

It has the LC0719-4001DC p board. I have no clue where to start. I tested pin 7 on both the p and a boards and got nothing. I don't want to have to replace the whole board. Any ideas which component might have failed?

    I found and replaced a bad fuse. the television fired up good for about 10 seconds then blew the same fuse. What could be the object sending to much power to the fuse?

    Which fuse did you replace? Knowing that can help determine what component is most likely is causing the fuse to blow.

Thats usually caused by a bad P board in most cases. usually its one of the transformers thats having an issue and it triggers the 10 Blinks.

SOURCE: Panasonic Plasma TV (TH-50PZ80U) blinks 10 times,

I'm not sure of how to solve this problem but I would be interested in hearing more about your experience. I'm a factual researcher for a law firm that is putting together a class-action lawsuit against Panasonic concerning the blinking light issue many of their plasma tv models are having. If you'd be willing to share your story, please email me at kiaeger@levjen.com.

I had 8 blink on panasonic th-42pz80u. I replaces power board and ss board but still get 8 blinks. What couls happen to the othe boards? Please help.


Hi Ha Phan.
When working inside of a TV be very careful about what you touch, Electrocution could result, unless you are familiar with electronics. They can hold deadly HIGH voltages, even when unplugged for days. Here is a link with a flow chart that can help you troubleshoot your TV. Some steps require a Multimeter to test voltages. You can even download the manual if you want. Hope this helps.

Panasonic th-42pz80u...dead set...red LED blinks twice at turn-on...the 15v supply on pin 1 of P7 comes up for a second then shuts down


I'm no expert but I have the same tv I'm trying to fix,different problem from yours.I think you can take a resistance reading from that pin to ground and if there is a short,you can start unplugging different boards and when you have the right one the short will go away,if not its the power supply.Put in a search on google with something like board layout for TH-42PZ80U and click on the link 11th generation and you can tell if I told you right or not

TH-42PZ80U blinks 4 times but, can't turn it on with TV button or the Remote.


4 blinks is power supply failure will need to bench tested and p/s replaced. Usually when powers supply's fail in the Panasonic they take out the A board and sometimes the SS board so be careful on repair charges usually NWR

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.

Power light blinking 10x


It's not necessarily the power board. 10 blinks is the Miscellaneous error code. Your TV knows something is wrong, but isn't sure what it is. It can be any number of things, including bad boards. Mine, personally, was multiple bad boards.

Panny TH-42PZ80U Plasma TV No display on Power-up


I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!
