My Panasonic plasma tv turns itself off and then back on again continuously
@halilh68 could be a bad power board, bad IR board or a bad remote. Try a different remote first and see if that helps. Also let us know the exact model of your TV and if it has the capabilities to connect to a network and does auto updates etc. In that case, you want to turn that stuff right off. If it does not, then unplug it and remove the back. Check your boards for obvious damage, like leaking or domed looking capacitors etc. Post some images of all of your boards and post those with your question. Use this guide Adding images to an existing question for that. It will allow us to see what you see.
Hi @mkjl22, If the same problem is occurring on two different makes of TV then there is either a problem with the power supply to the TV or perhaps there is some IR (infra red) interference going on with the signals being received by the TV. You didn’t state how long it is on for before it turns off and then turns on again, but initially try blocking the IR “window” that is usually found on the bezel below the screen to see if this stops the problem. Use a piece of cardboard or even a picture or book etc. Look in the TV user manual to find out where it tells you to point the remote control unit to on the TV so you know roughly where it is. Use the TV control buttons to operate the TV If doing this stops the problem remove the batteries from all the remote controls in the room e.g. TV remote, Firestick remote (if any)and then unblock the IR window on the TV and check. If it stops replace the batteries in one remote at a time (I think that the TV remote would be OK as it happened on a different model TV before which would mean a different remote). Also if disabling all the remotes doesn’t stop it but blocking the IR window did, then are there are any CFL lights (Compact Fluorescent Light) in the room? Check if they cause the TV to malfunction when they are switched on and off. Malfunctioning CFL lighting can cause IR signals to be emitted which may cause interference. If blocking the IR window in the TV doesn’t stop the problem, try connecting the TV directly to a different power outlet i.e. not via a powerboard (powerstrip?) and if possible also not on the same power feed from the power box (different fuse or circuit breaker). You may have to use an extension cord to try this.
I cut a hole on the back of the tv where the power board is and glued on a 5 volt usb fan .. used caulking to glue it and plugged the usb in a usb jack at the back of the tv fan is now exhausting heat out of the tv. and the fan only comes on when i turn on the tv. i know it needs a new power board but this has worked for me for a year now and has not done a restart since.. take the back cover off before cutting the hole so not to damage the power board.. actualy instaled the fan just above the power board. my tv is a panasonic tcp60gt30 and it has no internal fans.
