Television i have a mitsubishi 55 inch big screen and when i try to turn it on it turns itself back off and makes a static-sizzling noise. We have had the tv on without turning if off for weeks at a time. not sure if that is the problem.

Sounds like its going into auto protect shutdown. Try holding the imputand menu bottons in together for 5 seconds and see if the green light blinks out a series of blinks. If so notice what they are, should be a 2 digit code if its going into shut down. If not its a power supply issue. Also you can look the boards over for evidence of CRT fluid leaking on the boards, I have seen this happen alot to the VS models it causes corrosion of the components and you will experience no start up condition like the one your describing.
