Re: Panasonic Plasma TV LED blinking 12 times
Hi there guys. I am now having this same exact problem with my Panasonic Plasma TV and was wondering if you guys had the part number(s) for the P boards? I know they are different depending on TV model but it would at least put me in the right direction. Thanks in advanceComment

Re: Panasonic Plasma TV LED blinking 12 times
Hi I have a Panasonic TH-42px70b that sometimes works fine, picture and sound perfect, other times it can shut down and give the 12 blinks sound sos fault.
The service manual points to the h board or p board.
I have stripped the tv down and plugged in set and powered up and been on bench test for 8 hours or more with no problems whatsoever.
Now got me thinking is it a heat problem that is causing set to shut down?
Thermal fuse maybe on one of the transformers.
Anyone else had this issue please or any other advice appreciated.
Thanks in advance.Comment

Re: Panasonic Plasma TV LED blinking 12 times
you could try using a hair dryer to heat one board a time for a few minutes and see if it goes off.Comment

Thanks Vinceroger69
Have tried heating boards and set switched off while around t401 a couple of times and gave 12 blinks, left cool a bit put back on again and working, now trying to heat again and won't switch off no matter how hot I get it lol, is there a thermal fuse in t401 that could possibly be causing this issue, have another model of tv with fans fitted to top rail, wondering if I can mount these in set, just where to power fromComment

Hello everyone. 😀
As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.
Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
There are no devices that have exploded or otherwise show signs... -

I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.
So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
After doing a factory reset this problem was gone and the picture was back to...01-06-2025, 06:02 AM
