Panasonic Viera TC-P50S30 Does not turn on (power up). Have tried different outlets

Alfred The Great you did not tell us if your power LED is blinking at all. If it is not, you do want to check the power supply. Make sure that your set is getting power from the outlet. If that is verified, unplug your set and remove the back and check the fuses on your P board.

Check the fuses for continuity first. Make sure that your set is unplugged and that you do not touch anything with your bare hands. May become a shocking experience since the caps will still be charged. Post a couple of images of your boards with your question so we can see what you see.
