I have a Panasonic TH50pc77u TV that is totally dead. Where can I find a flow through troubleshooting guide? Thanks..

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.

No,Sound like the tv Plasma screen panel is dead.

Thanks! I did see that info about the totally dead unit. That's a great troubleshooting guide!

I'm calling it a day for today.

Thanks again!

At a guess, I would say no.

Your plasma TV likely uses an IR remote control, and although I have seen compatibility issues between IR remote devices, it is extremely rare.

The best way to test it is to remove the skybox and see if that solves the problem.

Send me your email if you still need a schematic. I found one online and can send a link or the PDF. [email protected]
