I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!

Hello,

The power supply board of the television is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help in solving the problem....

I'm no expert but I have the same tv I'm trying to fix,different problem from yours.I think you can take a resistance reading from that pin to ground and if there is a short,you can start unplugging different boards and when you have the right one the short will go away,if not its the power supply.Put in a search on google with something like board layout for TH-42PZ80U and click on the link 11th generation and you can tell if I told you right or not

An 8 blink error code means that your SS board is failing. The SS board is on the right side of your set, if you are looking at it from the back. This is a very easy board to replace.
