Mitsubishi WD-65734..TV powers up for about 20 minutes and than goes out and gives the bad lamp indicator (red light)..but your can turn it on again in 3 minutes. ..could this be a lamp or ballast ..or something else?

Could be the FMT pcb or the Dm pcb board you should check the caps on them and replace any faulty ones.

SOURCE: Mitsubishi WD-65733 no picture, electrical buzzes in series

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.
