Hi @carigeez ,

What is the model number of the TV?

Is the TV's standby red Power LED light on or off when power is connected to the TV?

If there is no red LED light showing, have you checked that the wall outlet that the TV is connected to is working OK?

What have you checked?


No red light at all, viera p42x5 50” tv, the outlet is working fine. It does this often and it’s some sort of safe mode when the power goes out or the tv is unplugged and it’s very frustrating.


Hi @carigeez ,

Usually no red light is indicative of no power in the TV.

I don't know plasma TVs that well so can only suggest that since you say this happens often, it to try a power refresh and check if it starts OK.

Disconnect the power from the TV and then press and hold the TV's Power On/Off button (not the remote's power on button) for a full 30 seconds and then release it. Reconnect the power to the TV and check if the red light is there and if so if the TV turns on OK.

If it does then the reset has worked.

As to why this happens, most probably there is a problem either with the power board or the A board in the TV and the power fluctuations are causing it to glitch. Obvious I know but the boards would have to be inspected and checked etc.

It may be better to do this when it is not working i.e. no red light, at least then you know what to look for as far as testing goes but if it is working it willbe harder as everything will test OK.

Sorry that I can't be of more help on this one. Perhaps someone else may know and have an answer to your question
