I own a panasonic Vieira led tv.
We turn our power out let's off at night. Today we switched it on and it was working for a few seconds. But for some reason it just turned off. No blinking red light. Nothing but a black screen.
We unplugged it for half a day, and tried it again. Still nothing. Our power is in full Woking condition. The power outlet we normally use for the tv is working also.

We've tried the, unplug it and hold the power switch on to the tv for 60 seconds then plug it in and turn it on manually. We've also tried the, leave it plugged in holding both the power button and a volume button for 20 seconds trick. Still nothing.

Any idea's as to what it could be and how it could be fixed please.?

Sounds as if the fuse on the power supply board has blown or the board itself is defective. You will have to disassemble the TV to check the fuse with a DMM and examine the power supply board for swelled caps, burns, etc. Be careful when working on electronics as capacitors can store enough electricity to cause serious injury, even with the set unplugged.
