The condition of your TV called power supply overcurrent shutdown. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating .I would probably also check the flyback circuit and flyback transformer although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

Mitshubishi plasma tv ws65869 wont start green led on in a sec off


Not a Plasma by the model number listed.

When green power light comes on and goes off a few seconds later:

Press and hold on the front of the set both the Menu and Input (source) buttons at same time for at least five seconds and let both go.

Power light will blink a two digit error code like: 2 blinks, 2 blinks and a pause and repeat it several times.

If set has been unplugged it clears the errors and you must turn on and when power light goes out repeat.

Let me know error code found and I will help

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

Panasonic shows multiple board replacement in sequence of boards that may be the problem. they start with the PA board as the most likely culprit start with that. how ever there may be 6 other boards that can cause a 10 flash code.
the PA board part # is TXNPA1BJTUJ.
