Question about Televison & Video

1 Answer

My TV has developed a loud buzzing sound. Tha lamp seems to work ok, and the sound seems to be emanating from the fan, which is working. Fan or color wheel? The picture comes on, but seems to deteriorate after a few minutes. The buzz is very loud, almost a grinding sound. The sound stops about 5 seconds after I turn the tv off.

Loud buzzing sound


Hello Jack,

That buzzing might be two things. It could be the color wheel or the ballast for the bulb. To check this you will have to move the projection section of the TV out of the case and listen for the sound in the area of the color wheel and the ballast. Try removing the color wheel power to see if the buzzing stops if it does then it's the color wheel is not and the ballast is buzzing then It's the ballast, and it will need replacing or if you know electronics you could try fixing the old ballast (I would suggest getting a new ballast).

Better still if you are uncomfortable working on the set you could get a qualified TV repair person to repair your TV .

I hope this helps,
Thank you,
