The buzzing noise you are hearing is from the lamp ballast as it strikes the lamp. that is quite normal but it should only be momentary. it should not be constant.

    The noise on mine is constant and the lamp was replaced about a year ago, but with no problems back then. We did move and thus moved the tv, but this is 3 months later we are hearing this noise by where the lamp is located.

If its a DLP with a high pitched or even fan like sound it is the color wheel--Mitsubishi does not sell them as a part---you would have to replace the entire light engine (expensive and may not be available any more on a older set) .

Remove the lamp and do a visual inspection.

Mitsubishi wd-73736 bulbs buzzing noise


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,

Buzzing noise from Mitsubishi DLP WD-52327 after replacing bulb


Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.
