So far I have had no good luck with Mitsubishi. I have had them send me two bulbs and had the tv repaired in the two years I have owned it. My last tv lasted 14 years with NO issue and didn't cost me $1400!! I have been told there is an air flow problem and power supply problems which both lead to low lamp life. I think that if Mitsubishi wants to avoid a class action lawsuit they need to start giving away free lamps for this model. Also, this is not localized to just the 52" tvs. My wifes ex has the 62" and it has the same issues.

The Ballast that ignites the Lamp could cause the Lamp to fail and/or cause a buzzing noise. That being said, the Color Wheel in the Optical Block assembly could also cause a similar symptom. If Mitsubishi would be willing to help with the Lamp cost, I would call a local Mitsubishi repair facility to install it and see if the noise is still there and find out exactly what is causing it. Mitsubishi Customer Service Phone number is 1800-332-2119.
I hope this helps,

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.
