SOURCE: Panasonic plasma TV model TH-42PD60U won't turn on

I had this problem in 2007 / 2008 here is what happened to me. Jan 09, 2008 - I also have brought the unit to the authorized Panasonic repair facility and the problem is a failure in the P-board which is the power supply board. The P-board needs to be replaced. The repair will cost $475 plus tax. $250 is for labor. The unit was nop more than two months out of warranty. This does not speak well for Panasonic. I have been researching the problem and it looks like this has happened to many of the Panasonic plasma TVs.
Jun 14, 2008 - As an update to my problem with the failed P board. Contacted Panasonic Service and talked to a customer service representative. I told them how I have purchased many Panasonic products and how unhappy I was with the failure of the product. They proposed paying the labor cost of $250 and I would pay for the part. I just hope it does not happen again.

I doubt there is an easy fix but your situation suggest that you have a bad ground on that outlet and a short in the tv tried to go to ground through your cable itself. Plug in an "outlet analyzer" to both outlets. They are under $10US at supply stores such as Lowes and Home Depot. Through a combination of lights, it will report the status of the outlet

What you described is a failure in the power supply circuits for your display. You would need a wiring diagram and expertise. internal exchangeable fuses are rare anymore. They are usually a set of diodes which must be desoldered.

You have to open it up. Check for busted fuse, or a burnt
part. Your Power Center PC800 just experienced an overload. It could have blown an internal fuse at the least
and a burnt out part at its worst.

TV suddenly shut off, blinking red light in power button

The TV's power supply capacitors probably went bad.

Check with a mobile tv repair co. to see if it is worth fixing.
