Question about Mitsubishi WD-65733 65" HDTV
Mitsubishi WD-65733 replaced burnt out lamp. now with new lamp inserted i get no picture on screen. The tv powers on. a series of eletrical buzzes and electrical light comming from board next to lamp. I think its the ballast. What looks like a capacitor lights up with electricity. This cycle happens about three times and tv powers off.
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.
