Before you investigate the TV and its power supply, have you confirmed that the outlet is still delivering the voltage? Sorry if I ask but you said you turned everything back on after the power failure and I didn't know if you meant equipment in the house or all circuit breakers in the house.

SOURCE: My TH-42PX6U TV went completly dead

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.

SOURCE: My Panasonic Viera TH-42pz700u will not turn on,

Good day sir, hi, at this point, you have no choice but to bring it to a service center, replacing the power supply board is not the faulty part, you may need to measure voltages, from the ac mains to the board and to its power output to the entire TV. There are several possible fault part;

  1. the power cord
  2. the power switch
  3. the ac inlet that accepts the power cord to the board.
If these things are thouroughly checked then you have no choice but to get professional help from the service center or dealer.

What is the red light blinking before the pause? If you mention that, it'll be a big help on diagnosing the problem.

When the power is returned after a power outage it can cause a power surge and damage electronic equipment such as a computer. This is a reason to install a surge protection power board and connect your computer equipment to a surge protection board.
The switch mode power supply may be faulty and replacing it may get your computer operating again.
If you cannot DIY then ask a friend or take it to a computer repair shop.

60" projection tv went black


Unplug the set from the wall for about a minute. Plug it back in and see if it comes back on. If the problem still persists then you have a shutdown condition, meaning a short or missing voltage.
You will need to call a technician to diagnose the source of your problem. If other appliances in the house were affected you may have a claim with your home owners insurance. Good luck
