TX-P50VT20E 10 Blink Code

[rgarcihm8]

Hello, i'm getting this 10 Blink Code on my Panasonic TX-P50VT20E, all i have done is this:

1-. Troubleshoot 10 blinks failure. https://imgur.com/a/wS3DR

This Troubleshoot said me SC board is defective.

2-. I've done su/sd resistance test without errors. https://imgur.com/a/juQEX

i'm not technician, only user and want to know if i can do more tests to sure is the SC board.

Thanks a lot, regards from spain.

Have you checked all the solder joints to make certain they are all good especially around any coils or where there are rivets. Also are all the securing screws in nice and tight.

What voltages do you have or are missing?

All solder joints good, securing screws too.

voltages i have or missing don't know what you mean, i test some voltages on the PBoard that i read on service manuals, but nothing special.

The back panel should have a label on it giving various voltages which should match the test points on the circuit boards. Also the circuit boards may well show other supply voltage test point. Without pictures of your boards it's all guesswork at to what they should be.

Most likely SC board multiple components shorted. If you disconnect the SC board and switch on the blink code should change to 7. Also check Q661 on SC board - most likely shorted.

Hello everyone, I need help, I have panasonic tx-p50vt20e problem is tnpa 5081, I got a picture but I'm losing it, after some time I buy another TV the same model, and order y plate is correct, I install it in the TV but I only get half the image, in the upper part has a picture but in the lower no picture, I place the same board in another TV that is the same model, I get the same picture, but I got the picture on the other board but the picture was poor, but it was whole, is it possible that the nand upiso error on the processor board, and that's why I do not have the whole picture on a single TV set, please, for help
