TV PANASONIC TC-21RX20C indicator blinking - Panasonic Televison & Video

A 10 blink code on a Panasonic plasma TV typically indicates an issue with the power supply board. You will need to consult the service manual or contact a qualified technician to identify the exact part that needs to be replaced.

According to page 13 of https://www.manualslib.com/manual/421925/Panasonic-Tc-P42c1-41-6-Plasma-Tv.html?page=13#manual it indicates 5 Volt SOS.

Service manual seems to have detailed instructions if you feel handy to open it up.

Have you tried going into the "settings" and changing the aspect ratio of the picture? If not, try that. I hope that helps?

These blinks are fault indication, and known as blinking codes.From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV.This will make repair easy. For more information, check the link

My panasonic TC-P50G20 does not power on, just I have 4 blinks on my power indicator light. What error does that mean?

Panasonic utilizes the blinking light as a form of self-diagnostics, similar to the "check engine" light in your car. If you've ever experienced that, you know that a check engine light could indicate anything from a loose gas cap to a major failure.

Panasonic uses the number of times the light blinks, to aid the technician in trouble-shooting the problem. The blinking light indicates an area of concern and helps the technician to isolate the problem and order the correct parts. This in turn speeds up the repair process, keeps parts cost down, and helps both you and the servicer by allowing the technician to complete a repair in one trip in most cases.
So contact an authorized service center.

10 blinks for this tv is not always an A Board issue. It can be a problem with the power board as well. A technician should look at the set to dertermine where the problem lies otherwise it is just a guessing game of inni minni miny moe.

Hello,
Your TV 7 blinks indicates you have a faulty ss board its bad or needs service SS Board (SS Data Energy recovery and data driver). So check ss board for faulty components.

Problem is caused by voltage irregularity. Pulled plug for an hour and then plugged it back in. TV reset and it works fine. If this does not work it needs a TV technician.
