Question about Mitsubishi WS-55513 55" Rear Projection HDTV

1 Answer

I have a mitsubishi 555413 that I'm having trouble with it staying on ... the power light is blinking and the then when you turn on it stays on about a minute then shuts off. Then it can be turned on then immediately goes off. I have tried unplugging for hours and same problem. I have read about some fixes on other models, please advise if you know what the fix would be (specifically as my husband is a novice at electronics). Thanks...

That is most likely the very all to common power board failure. The capacitors overheat and burn out very easily on these. They can be tested with an analog meter. Each component has it's own power rating on them. Usually but not always, the caps on the power board will look swelled up when bad or there will burn marks on the circuit board.

    The power board has capacitors that can be tested with an Volt/ohmmeter. Each one has its own voltage ratings on it. The reading on the meter should match the number on the capacitor. There is also a flyback that can be tested with a voltmeter. A manual can be found on retrevo . com

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?
