Tc-p42g10 5 BLINKS - Panasonic TC-P42G10 Plasma TV

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name to your set, in its search box on the right side. View it on a desktop or in web View.. Mobile view has no search box.

It almost sounds like a capacitor issue. Any and all televisions have quite a few of these and any of them could be the culprit.

13 blinks means a communication error on the A board (main board). The part number for the main board is TXN/A10PYHS. I would recommend TSM for a replacement board. Good warranty and price.

one or more transistors
easy fix cost about 14$ to 30$ with transistors but the heck is you have to take out most of them cause they are in parallel to find wich one is shorted......hope this help

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

Unfortunately the set will need serviced. I would contact Panasonic or whoever you purchased it from for warranty information.

Google the model number with 3 blinks or error codes and you should find it.

thought I would post this here for everyone.
