yup i have the same issue apparently its cause of the tv drawing lot of power dur to its fast start up . try plugging it in to the wall direcly ie with no other devices plugged in. i also notice that it only happenes if i have had the tv off for a while eg over nigt and not if it turn it off wait a few mins and turn it on so it must be some thing with the power. i would still call samsung and see whats up.

Same issue from my LN46B750 The speakers were replaced along with the mother board....no help. Still on startup....especially after sitting for a while it will buzz for a few seconds and then go away. Have it plugged into a protected power strip.

I just bought a new unit and not having the problem mentioned. Have you tried checking if there is a firmware update available and apply it?

I had this symptom as well and my unit eventually stopped working altogether. I had to return it for warranty replacement and I was charged for return shipping even though the unit failed within 3 months of purchase. Much to my frustration, the buzzing symptom has started on the replacement unit now (only used for 2 months) and I am expecting this unit to fail as well given my experience with the previous unit. I don't know if this is unusual for Speakercraft products, but I will never purchase from them again. At this point, it isn't worth my time or money to ship back the second unit for warranty replacement.

Thanks for the workaround. I agree it stinks to have to do this, but so much functionality for the price I probably will live with it. Maybe if we complain (and pray) enough we'll get a firmware upgrade.

I don't have this model myself; I have a different model, but have you tried unplugging it and resetting it? Sometimes they just get a "little hiccup".

Return it, I have not had this problem. But the problem will never get better if it is running the current firmware

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.

We had the same buzzing sound, it was covered under warranty, they came out and said it was something to do with the speakers. They installed some sort of foam pieces around the speakers and the buzzing stopped.

ok. Got the replacement.1) the static sound still exists from 1-8 but it's half as bad as the previous unit2) now sometimes i get a buzzing sound when the volume is at 0This one was also manufactured in October 2010.I'll see if this bothers me enough, else i'll send it back.

I have not experienced those issues. I recommend checking to see if there are any firmware updates for your unit. You have to connect your unit to a internet connected computer to perform the online check and updates.

I have a slight buzz from mine's as well, really noticeable when the volume is on a lower lever (anything below 15). From what I have read, this is fairly normal since a lot of energy is used to heat the plasma. Also, since I'm only about 7 feet away from my set, that might be part of the reason why I notice it. Did the samsung tech support cost a lot to come out to install the insulating material?

Thanks Wagner. I will set it that way and see if anything changes over the next day or two and post back here.So much for a day or two, I just tried it and it is very loud now. Mine wasnt refurbished, I bought it new in the package. Werid bug for sure.

No, the buzzing sound is always on, unless you are on mute. I had mine for a couple of months now and it seems to have gotten worse

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.

I've had the same problem since I plugged it in. A small buzzing sound that gets louder. If I tap the earpiece where the mic arm is attached it goes away briefly. I sent that pair back, but the new set does the exact same thing. Any help would be appreciated.
