Re: Panasonic P50ST50B plasma TV: 13 blinks
Anybody knows if I can use a P50ST50C board on P50ST50B?
Any idea?

Re: Panasonic P50ST50B plasma TV: 13 blinks
I see, so you think I should just go for a new A board (or look for a reballing service).
Unfortunately I cannot find any online for this model...
Do you know if I can use any TNPH0989 to get it going? Will the board for p50st50C work (I think that's the asian model)?Last edited by faenil; 09-18-2020, 03:03 AM.Leave a comment:

I see, thanks for your input.
Is there anything I can do to make absolutely sure it's not an issue with the psu? (provided I cannot test it in another tv)...Leave a comment:

Oh sorry, you needed the pin layout...
Thanks for posting it.
I will be back on Wednesday and test the TV with only A and P connected.
Meanwhile I might be able to order a P board so I can have it by time I am back and I can test it
It was my fair that the P board could be at fault... Or, well, I was hoping it would be P more than A.
I will keep you posted, thanks for your help!
Feel free to provide any other pointer you may have...

I tried unplugging the other boards, I think it did not make a difference (I will be unable to test on the TV until next Wednesday.
No, I don't think I have ever seen the VSus high.
F15V seems to be fine, while P15V is stuck at 2.15v
I will convert the pin readings from my previous post in a bit, I think I wrote everything in the first post, it's just the pins I did not mention were 0v...Last edited by faenil; 09-17-2020, 03:50 AM.Leave a comment:

Re: Panasonic P50ST50B plasma TV: 13 blinks
well...yeah, that's what the blink code reports ^^
I find a bit strange that pins 13-15 are stuck at 2.15v, is that normal? Could it not be that the issue is actually in the PSU?
Is there anything else I can try, given that a replacement board is nowhere to be found?Last edited by faenil; 09-17-2020, 03:28 AM.Leave a comment:

Panasonic P50ST50B plasma TV: 13 blinks
Hi everyone,
disclaimer: I am a newbie at electronics, trying to learn as I go This is my first troubleshooting experience.
My Panasonic P50ST50B has stopped turning on a couple of months back, and I am now trying to understand what happened and if there is a way to fix it.
The red LED turns on when you plug the TV, pressing buttons on the remote will make the LED flash green fast for a few seconds.
After 2-3 minutes of no activity, the PSU clicks twice and the LED turns red again and blinks 13 times.
According to the technical...Last edited by faenil; 09-16-2020, 04:34 PM. -
