humming / buzzing noise: Does anyone else get a faint buzzing / humming noise when changing channels or when the tv is displaying a lot of black on it.

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

I have the same issue with my two-week old 42B450, as well. The plastic bezel makes faint crackling noises as the unit warms up (lasts for about 30 minutes). It is definitely the plastic bezel since I can duplicate the sound by pressing the bezel along the top edge of the TV. Another Amazon post said that they had the same issue and so they returned the TV for replacement and the second one did not make the sounds. Am curious if the Samsung rep mentioned above actually has a fix for the problem.Except for this issue, the TV is excellent in every way.

Have you tried switching your cable? I've never gotten any humming when playing this, either through a tube or solid state amp.

Is the buzz only through the TV's speakers or is it heard no matter what? I have a soundbar and will shut the TV's speakers off. Im really interested in this TV.

When it starts to sound like there is a grinder inside of the TV and it starts to shift to black and white it is time to be replaced. It's a fairly simple process if you have small hands like I do.

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

Does anyone know if the Samsung B850/860 buzzing sound is coming from the Tv only or if it also comes from the sound system when you have it hooked up to separate speakers?

hi i bought this tv and got it last wednesday and i notice when i have the picture on dynamic that the buzzing is so distracting i can harldy watch and then somewhat better on standard and then hardly noticeable on movie mode. I dont really like the picture on movie mode though.

mine doesn't hum. I wish I could help. Maybe it is the model. I had one, that i loved, and one day, it just quit working. They didn't make that model anymore, and I had to cut the plug, and send it to them, and then they sent me the most similiar model. But I really loved my old one. It was beautiful. This one works great, but is not as aesthetically pleasing to the eye. :-(

I also use a dimmer and no buzzing sound for me .Make sure the hot and neutral aren't switched (black is hot white is neutral)and the fixcture is properly grounded(green).

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.

I have a buzzing issue. Try it for two weeks and ended up sending it back. LOVE PQ of this TV though.

I seldom experience a hissing or crackling. When I do I just scan and the noise goes away. This happens very infrequently to me. I rarely have any problems with hissing. I found out a while back that if you are too close to the TV you may experience a hissing. Just move a little bit away and it will clear up.

No, thanks goodness, I've not experienced it having a buzzing sound. I know the annoying sound you are talking about because I getthat buzz from a different type fluorescent fixture in my laundry room.

Did you experience this crackling when you turned the TV on too? I have a Samsung 4671 and it crackles when I turn it on and off. I actually returned the first TV and the second TV crackles more, which makes me think it may not be the power supply. However, what did you have to do to remedy the problem?
