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.

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.
