Question about RCA F27628 27" TV
If you have a converter box hooked up to the tv as well turn the volume down on both devices and bring the volume on the tv up to mid range, then increase the volume on the converter.....one is overriding the other

I hope this will help you, but next time you really should write in more detail. Does the buzzing coincide with different brightness levels on the screen? i.e, the brighter the buzzier? if so read on. please note - If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Its going to be some inductor or coil that's vibrating with the AC signal going through it. The more the current (i.e. brighter image) the more the magnetic field therefore the movement and louder the buzz. Many components of this type have some sort of adhesive applied to them to damp this out. Maybe its come loose in your set? I wouldn't advocate prodding around inside the set, but an engineer might be able to stick an insulated screwdriver around and find out what's causing it. (But I bet as soon as he takes the cover off - it'll stop..... then start up again as he's driving down the road......) Good luck

I thought my sony trinitron was going out, this buzzing sound would come and go and the picture would distort at times, at other times it seemed to go away but I decided it was going out as it's over 5 years old ... my husband had a look at it and somehow the tv channel had been changed from channel 3 to channel 8 (we have cable) and the wrong channel was causing the interference. Once he put it back on channel 3, the cable worked fine, no more buzzing, no picture distortion! I was ready to throw it in the junk pile!! hope this solves some of your tv buzzing problems. when I turned on the tv my cable channel came up so I never thought of the channel having been changed but my hubby said it was a similar channel but had alot of interference because it was not the proper channel for the tv to be on to have cable come through clearly.
