I have Pnasonic plasma T.V model TH-50PV30. It tends to switch off on its own. Some times it may go on for long time without doing it but at times it switches offin a few minutes , leaving the standby button flashing.

It may due to the ics getting heated up then its normal temprature.causing the tv to go off.try cold soldering on the main board which sometimes solves the problem, otherwise change the faulty ics

You can check the board where the components are mounted and resolder any that look bad. a brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.

In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace.

If this does not correct the problem, you may need to have your TV serviced.

It seems to be power problem in your tv .

You need to check whether the fuse is blown . If so you need to replace it .

Replacing fuse will work at sometimes .

without having a play with the remote its difficult to know exactly ,but either way their is a fault with your remote or the reciever in the actual set and the only way to get this sorted is the man with the right software to plug into the TV to diagnose the problem ,sorry to say it and that is to return the set with the remote to the dealer.

I have a pnasonic pt-53wx52f the tv turns on the screen comes on for about a second and tv shuts off and the led light blinks 3 times any clue what this could be?


Thats the error for convergence shutdown. You can get the repair kit for your model at www.tvrepairworld.com which has the parts and the CD with detailed instructions. the kit for your model is the PT47WX52 as that applies to your model number as well.

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie

Well don't tamper with it just return it, there is serveral problem that may cause this, most likely it is the power supply board.
