Question about Mitsubishi WD-65733 65" HDTV
Posted by Anonymous on
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.

Testimonial: "very helpful. this was my first thought! thank you!"
You need a new projector bulb. Google up your model and buy the best warranteed one you cAN FIND. Buy a "caged assembly" and not just a bare bulb.
Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.
Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.
Treat yourself because you've just saved yourself a trip from a repairman!

It is probably the wiring. Try buying a new power cord.
If not than it is just malfunctioned.
