on the back of the TV where the power cord plugs into the back of the tv there is a small black on/off switch- it's not as obvious as you would think.... but that was turned off. Not sure how that happened since the back of the Tv was never touched when it went dead- but I unplugged the cord from the back of the tv and from the outlet and reset that switch and it worked.

Ok, I hope to save you a lot of money. I finally figured it out. There are a lot of hints on the web. Once you get it fixed you will regocnize them. So here is what I did. Had to order the 2 fuses for the main power board from panasonic. The fuse number is K5D802BNA005. You only need two. Once I changed the 2 fuses I go the tv to power up but the red light blinked 10 times. This indicated there is a power problem.
There is a high probability the P board is bad. You can check this by checking th voltage on the number one pin on the p10 connector. TO do this you have to measure the voltage as you power the TV up. you should get 14 volts. if not the board is bad. I bought one on Ebay for $120. Put it in and it works. good luck.

check the power inverter on the power strip. also check the caps on the board and if any of those caps have a round top it is bad and needs to be replaced. i hope this helps.

Check for bad solder joints on the power supply baord first, especially around C310 (GRAY cap as shown in my pictures)
