SOURCE: press power button green light comes on.But no picture no sound,

I have had my WS-65511 fail like this, first at 4 years, second 2 weeks later, then 3rd time yesterday (4/14/2009). In past, the tech replaced a thermal sensor p/n 299P313010A (but Mitsubishi says that part is not for WS-65511 and that it does not have a thermal sensor - go figure). It is a white rectangle with about 30 pins in 2 rows and is soldered onto a board in the TV. List price is about $25. Might be your problem.

SOURCE: my mitsubishi 55" will not turn on... when I press

Hi:

The most common failure for this model is the deflection board assembly or commonly known as a Large Signal board. The unit is going into shutdown, mode because no high voltage. Unless you are strongly electronically inclined I suggest you try to replace the deflection board.

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Reciever wont stay powered on


I fear that there's no easy fix. Sounds like the power supply or the board which controls it is bad. If you're not an electronics repair person, it'll need to go to a repair shop.
