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 several of the units and there is not a buzz noise only a hmmmm like a fan. I think something must be lose in your unit. I can put mine on silent and I don't hear it at all...try that....if its still buzzing then something is wrong. They are great units.

No buzzing on my unit...everything works fine. The buzzing is probably electrical interference for which you will have to pinpoint a cause

i"ve been planning on getting this one but was just waiting for another coupon. As far as my research goes, there is nothing wrong with this TV. The buzzing sound some people report doesn't seem to be a major issue or at least it's a fixable one. I think what's going on is Amazon screwed up something and enough people complained so they pulled it until they can get to the bottom of the matter. I tried contacting Amazon to ask if there was a chance it might be available before the coupon expires today, and all I got was the same vague "Item under review" reply. The way I see it, they should extend the coupon for this one till the TV is available again since it's because of their screw-up that we can't buy it. i"ve been planning on getting this one but was just waiting for another coupon.

Yes, I have the same problem. I have learned to work around it. I make sure that I turn the main switch off, when I am not using the fan. I will check the channel switch, as suggested by other users. It is a very good fan, I would not replace it.

This fan noise complaint is absolute rubbish. Unless you watch TV at volumes lower than 5 on the TV with a sleeping baby in the room, you're unlikely to hear anything. I have had my TV for a month now and have not heard anything from the TV. Maybe it's because the fan on my PS3 or the fan on my HD-DVR are louder than the fan on the TV.

I have had my tv for about two months now. Have never heard any kind of buzzing noise. The picture and sound is great. Plasma screen is bright and clear. Love it so far.

I just got delivery on my PN50B860 and no buzzing. My guess is that given all the negative publicity that it is fixed. No problems and the flat panel is awesome! Try contacting Samsung technical service to confirm as they should be able to inform you if the issue has been resolved.According to a Samsung customer, (http://reviews.us.samsung.com/7463/PN50B860Y2FXZA/pn50b860-50-1080p-plasma-hdtv-reviews/reviews.htm) the buzz issue cured and there is a tech repair sheet out from Samsung to fix it so the newer TV's should be fine.

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.

I had surround sound and two of the 7 speakers hummed when I put the Direct TV HD in "pause." To fix this problem go to the Direct TV remote, setup, settings, audio, and turn "on" dolby digital. Mine was off and caused the hum!

A replacement cable may be needed; make sure it's balanced otherwise you'll keep getting a humming or buzzing. Best suggestion I have, always a good place to start though.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

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. :-(

Just got one on Tuesday 2/9/10. Same buzzing problem, but found out it was getting some type of interference from our space heater. Look for something that may be causing the same thing in your home. We turned off the space heater and now we're colder, but NO BUZZING. Hope this helps!

Why? because stops working and you no longer have a viewable picture or is making a lot of whining or buzzing noise indicating an impending failure. When? When you no longer have a viewable picture or can't heard the tv sound because the buzzing is too loud. In my case, I'm hard of hearing in some frequencies. The buzzing happened to be in one of those deaf zones so I barely heard it. The family complained about the noise so I ultimately replaced the color wheel. I did make a difference in the sound. Upon examining the old one it spun and wobbled on its bearings or what was left of its bearings.

I received my replacement about a week ago. I turned on the TV, and there it is again - the buzzing sound exists. That's two TVs, and both are the same. I do admit that the picture quality and everything else is very good. I'll probably return this, and go with another model.
