I have the same problem. Panasonic troubleshooting says to unplug it and replug in a different outlet. I tried but it did not work. 
But this advice may be the best.  http://stafford.typepad.com/the_next_america/2004/02/panasonic_plasm.html
It is saying that the TV may be protecting itself if there is an ungrounded plug. Test your plugs before you go on. Best thing is to get one of the simple three prong plugs with the lights on it that tells you the state of your electrical circuit

My Panasonic viera wont turn on from standby. It has a solid red light, no flashing


Hi Cloda,
It is mostly the power supply section which gets damaged due to power surge. In many cases the damage is repairable. Please contact some local TV tech.
Good Luck.

The TV switches it self off


Sorry to here about your TV problems but it is almost imposable to help someone with technical problems if they don't list a product, model or P/N number.
Either-way, I would try moving the unit in an area where it has more breathing space if poss-able.
Also, is the unit in a air conditioned area or in a Damp basement or Florida room ?
I would also, go on line and see if Panasonic has any call backs on this unit.
This may be a feature which can be reset without to much trouble.
Next time please list the size & model #.

Television turned itself off and won't come back on again


Tracy it sounds like a power supply problem, not anything you have done.This day and age the new electronics are only built for min running requirement, as in the working capacity of the power supply.Not like a few years ago when things where built to last and some still do.

It has a standby mode thats why most things have a led to show you if its on or off.This only come about for some reasons and that was to keep the old Tube Type Teleivision warm so you have instant picture, if you have turned this type of teleivision off at the wall it would take a few minutes to get a lets say a stable picture.
Enough of showing my age.

But this means the the powersupply is only in sleep mode only and uses bare min, to run and when you push the power on button you have life and then your picture.
Try this if and when it comes on and stays on, then it goes off on you, turn it off from at the wall and leave it for 5-10 min and try again, if it comes alive its a heat problem in the supply and maybe a dry joint which needs to be looked at.
If it does not try turning off and on at the set not at the remote, it could be the remote section is not working properly and have the same sort of fault. If you think it could be in the set up, try your sleep mode set up, it could be turned on, so check if the TV goes off at the same time say 5 min's everytime??

If it's the first fault you will have to get it back under warranty very quickly, these are inherent problems, companies want the dollar and not so much the quaility you get....

I hope I have helped???
P.s. if its the type where you have a power lead that plugs into the set and the wall Check that too, I have fixed many of things because the moulded lead has let the pins inside them open up..
Think basic first ok!

Check the 2 main interconnection cables (24pin and 26pin) rear of PDP and Tuner box. Make sure they are firmly connected. (Loose connection of 24pin will cause no power on symptom.)
