Question about Televison & Video

1 Answer

I have a Panasonic Plasma, th-50px60u. The power button blinks 10 times pauses 3 seconds and then blinks 10 more times. I got some direction to replace the tnpa3761 board. That has not solved the problem. What is my next step now. I have seen something about an H board too but not sure if that is correct or what part number is.

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.

My panasonic viera plasma TH-42PX80U will not come on. tried plugging tv directly into wall, no go. someone somewhere suggested holding power button down for 10 seconds, did that. no response with remote,...


Hi:
You will need to count the number of red led blinks on the power indicator, if it is at least 10 then replace the power supply it is faulty, In my years of servicing panasonic Plasma, power supply failure is about the most common failue in this class of television from this manufacture.

TV clicked and went blank...no picture, no sound. Power light blinks ten times in one second intervals and then pauses for about five seconds.


Most problems with TV not turning ON is a power supply related problem. The relay click are a normal process that powers up the circuit boards. Right now the TV is most likely in " Protection Mode ". The TV detected a bad circuit board and it will prevent the TV from fully turning ON. This keeps the other circuit board from being damaged. The power light blinking is a code.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet. This will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, blinking light codes, test points, and part# lists. Usually, cost under $20.

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