Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Are you certain it is blinking 11 times?
Thanks for confirming. I ask because that is not a valid diagnostic code.
It still means something is wrong, but it is an unusual pattern, which pretty much always means a bad main board.
This tv actually isn't that old, it is a 2013 model, but for a bad main board I would not consider it worth repairing. The board is about $250, money that would be better invested in a new 4k LED tv that you could get in the $500 range instead.
I can help with finding parts or replacement recommendations if you'd like though.
My apologies for the news,
Are you sure you gave me the correct model? What you referenced (you are missing part, I assume it is a TC-P55ST60) is a 2013 model, so maybe you had a typo there?
Okay well if it is a 2008 model, an 11 blink could be a bad fan or a bad PB board which is basically a fan control board.
Similar answer though, the cost would be a bit less to repair but the bigger problem is that it is nearly impossible to find parts for these and it is significantly past its service life at this point so I would lean heavily toward replacement vs repair, unless the board is readily available and very cheap, which may then be worth a try for repair. I'd really need the full model number to check on parts though.
That is a closer fit yes and that would be an 08 model.
This is the part you'd be looking for, luckily cheap and available: http://www.tristatemodule.com/TNPA4243AKS-Panasonic-TV-Module-PB-interface-p/tnpa4243aks.htm
It is possible but fan failure is actually less likely, you would have heard some noise out of them typically.
It is a plug and play part, no soldering necessary.

I would stick with the original part, it won't work properly to put in the different model. I do see a few available here: http://amzn.to/2jJyvsK
