Re: Panasonic Plasma TV LED blinking 12 times

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 from

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...

Hi all

My name is shawn and I'm an electrician by trade, I'm into learning how tv's work and seeing if I can repair any as a bit of a hobbie.
I live in the uk and from a small town in cornwall, ie st Michaels mount land.
Look forward to hearing from you all and for the help in advance to any problems I may have. ( only regarding to tv,s I promise )
