Question about Mitsubishi VS-50705 50" Rear Projection Television
Feel fortunate for the 10 years; owners of sets failing just after the warranty are really angry.
That length of time tells me that the power supply was better designed than most but is now failing to turn on and run. Modern supplies are very complex and demand a high level of component quality, far more so than the older (and less efficient) type called 'linear.'
The supply assembly is almsot always on a separate board and you should be able to recognize it through the relationship to the AC power coming in and the fact that they will have physically larger components, some cylindrical (capacitors) and others block-like devices (chokes and transformers.)
Look for an assembly number on that unit and contact Mitsubishi service to inquire about the replacement and/or repair cost of that board.
You really have been lucky since most modern sets don't run half that time without failing.
