Question about Panasonic TH-42PZ77U TV

1 Answer

Blinking red light of death

This morning, after approximately eighteen months of loyal service, our plasma television bit the dust. The model is a Panasonic 42PZ77U purchased from Sears. When the power button is turned on, a red light flashes seven times and then it turns back off. We've followed all of the recommended troubleshooting steps, but the darned thing is toast.

Has *anyone* found a solution to this problem? I realize that 3% failure rates are the norm for the industry, but this particular model seems to be unusually flawed. If anyone starts organizing a class action effort to seek justice for Panasonic consumers, I will be thrilled!

The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

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