This sound could be a component on the circuit board coming loose and vibrating. Usually, this is an electrolytic capacitor. It could be some dust or foreign object has gotten close to the power supply and is causing a slight current leakage. You should have it checked out. If you get in there yourself, make sure you unplug the unit first. On the older tube tv's this sound would have been high voltage leaking from the anode wire.

SOURCE: Buzzing sound

Hello, This is a problem with the switching transformer or the ballast used to fire the backlight. You will have to replace the ballast and or the switching transformer soon. In order to replace these items, I would suggest taking it to a qualified TV technician for servicing. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

TV making loud buzzing sound


More sets than you might imagine have this kind of problem---I a regular TV it is usually a transformer that is vibrating hard enough to make the sound---the higher pitched sound is just that--a sound.

If this is a direct view(means not a flatscreen and has a Glass Picture tube it will be either the high voltage transformer or one of several smaller transformers.

This can usually be fixed---seen a few so loud the cats in the house run away.

Let me know model number of set for more information.

On chance it has the high voltage transformer I attach a photo of what that looks like.

I have comcast and get buzzing from the box when everything is off. Do you have the option of unplugging it and having the t.v. on by itself or will the provider have to come reprogram it. If not, disconnect box to rule out t.v. before t.v. warranty is out.

Loud buzzing sound


It is the color wheel. They are usualy less than $150. I recommend having a Samsung authorized service center do the work as it is very difficult for someone without the experience doing this particular job. Labor cost should be $300 or less.

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
