I would check the internal fuses, should be 4, also check the output of the power supply, could be your y block is gone or your power supply.

Mitsubishi WS 65513 turns itself off


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

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

Went away for a week plasma turned off at mains came back turned tv on it normally gives 3 clicks then comes on but it only gives 2 clicks,power is going to the tv as it gets hot you can see it light up...


the problem is going to be internal and i would recommend a repair serivce.

Potential causes for the problem are:
  • Turning the main power on while the tv is plugged into the outlet.
  • A power surge or dip
  • The tv being bumped or dropped
  • the tv being exposed to warm or cold temperatures.
