I've had my PN50C7000 for about three weeks now, and I'm happy to report that I've had no buzzing whatsoever.

I got it from Vann's (vanns.com). Fast delivery. The driver was very helpful every step of the way including taking it in the house.

I have the PN58C6500 and it has the infamous laser beam directional buzz...
I sit 14 feet away and I can hear (and feel in my head!) the buzz easily over normal listening volumes. The set is totally quiet outside of the beam coming from the center of the screen.

No buzz on my PN58C7000 unless I press my ear against the back of the tv. Of course, that's how I normally watch TV...

I purchased a PN58B860 a few months back and listened to the buzz for 29 days (The store had a 30 day return policy). I returned it on the 30th day.

Tonight I finally had a chance to visit a local retailer (Fry's) and evaluate the PN58C6500s side-by-side with the PN58B860. After turning off the sound on all electronics in the ENTIRE audio/video department, here's what I could tell:

1. Standing directly in front of the PN58B860 (10 feet away) I could clearly hear the buzz, even in a noisy retail store. (I pulled a couple sales associates over to educate them since they both had no idea what I was talking about. One could clearly hear it. The other couldn't.)
2. Next I stepped in front of the C6500. It too had a buzz, but it didn't seem to be as severe. I went back and forth about 20 times, listened near and far, to make sure my assessment was correct.
3. After that I stepped down the line and listened to all the plasmas in the row. Among them a 58" Panasonic (couldn't hear anything discernable) and a Samsung PN58C550 which seemed to have a very slight buzz, but definitely less discernable than the B860 (my standard for buzzing).
4. They had a C7000 in a different section of the store, but it was too noisy to be able to tell if it too had the buzz.

A couple other things I noticed were that the C6500 and C550 were noticably cooler to the touch (seems the claim that they use less energy than last year's model is accurate). That said, I also felt like the picture on the B860 was slightly better than the C6500. The blacks seemed to be slightly deeper. Glare on both were about the same. Color-wise they both seemed great.

Now my dilemma is whether or not to go with the C6500 or C550. From what I saw in the store, the picture quality between the two was very similar. Only difference I could see was the thickness of the tv itself.

I just returned a 42C450 that I purchased through amazon for the master bedroom. Well, it buzzed slightly, enough that it was distracting in the bedroom, not soo much watching it head on, but when you walked by it the buzzing from the sides was very noticable. Bought a Panasonic 42C2 set, and it is as quiet as my Pioneer, very happy with the swap...

We`ll never know till we actually get one in our house!! I think the chances of getting directional BUZZ on 2010 Samsung models is 50/50 !!

Let us know which one you go for and if the buzz is a problem once the TV is in the house.

I've had a PN58B860 for two weeks... Though this is a 2009 model, it was manufactured in 02/2010. The buzz is barely audible only from 2-3 inches away in a dead quiet room (basically, holding ear to the set). ..Though it is now mounted flush on a wall, the buzz was no more audible when it was mounted on it's stand and set on a cabinet 2 feet from the wall. Perhaps Samsung made some sort of running production change that solved this problem. For me, it's a complete non-issue. If 3D is unimportant (it is for me obviously), this set is a terrific buy. ...The picture is phenomenal. ..Much better, imho, than the UN55B7100 it replaced (flash-lighting, uniformity issues).

Hey, I have a B530 that buzz's (non directional) and have the chance to exchange for a C540 if I kick in about $40 to cover the difference in models. Should I do it? Or will it buzz just as much do you think. I can hear my B530 while watching the TV during dialogue or quite scenes and it's distracting. Of course after 2 samsung techs taking the TV away for repair no fix.

Yesterday, after sending back my UN55C8000 due to flashlighting/clouding, I took delivery of a PN58C8000. As it turns out, it's a buzzer and I wanted to relay this info to the forum....

I, being a guy in his mid-forties who grew up playing guitar in rock bands, listening to LOUD music and flying helicopters in the Army, suffer from high frequency hearing loss and a moderate case of tinnitus. That said, I noticed nothing in the way of buzzing from this set. My significant other on the other hand, pointed out that she was hearing a loud humming noise from the set sitting dead on center and 12 ft away. After doing a lot of observational investigation, it seems that:

a) sitting dead center the hum is unmistakeable and she can hear it as far out as 30 ft (the farthest she can get from the set dead center). I "blind" tested her having her close her eyes and then turning the set off/on and also rotating the TV on its stand and she 100% of the time could tell when it was on and when she was on axis.

b) moving to the next seating position off-axis (about 2 ft off axis, 12 ft away), she could hear the hum but to a much lesser degree.

c) moving off axis so as to be sitting past the edge of the set's screen, she heard no noise.

d) during normal viewing noise levels, she did not hear the hum even on axis but when the program content silenced, she could.

e) I cannot hear it at all from anywhere

That said, I broke out my RadioShack Sound meter and mounted it on a tripod, silenced everything in my home and took some measurements. I had the meter set to "A" weighting, slow response, 60 dB. I positioned the meter dead center and varied the distance to the screen until the meter indicated 60 dB exactly (about 2'). Moving the meter halfway to either side of the screen dropped the reading to 58 dB. To the edge of the screen, it dropped to 56 dB. Once it went past the edge of the screen, even by inches, the meter's reading dropped below the lower end of the scale.

I am going to run the set a couple more days and see if this changes at all but, if things don't change greatly, this set is going back.

I just bought a PN50C450. I can hear a buzzing noise from the back of the TV when I'm very close to it with no sound on or being made in the room. As soon as I sit on the couch which is about 10' away, no signs of buzzing at all. Very happy with the TV so far, had it for about a day and a half now but I'll be keeping a close ear on the buzzing to make sure it doesn't intensify before my 30 days is up...

Mine has a nasty buzz, as well as a cracked screen. I am guessing they are related. My PN59C8000 came today...apparently others are experiencing the same problem.

I have a 50C6500, the only buzz I hear (more like static hum) is when my head is behind the set.

I work at a pretty large electronics store and have known about the Samsung buzz since last year and was going to pick up a PN58B850 as they were going discontinued but figured Samsung surely would be able to fix the buzzing issues as I saw a countless number of returns for that exact reason.

Once we got the PN58C6400's in I was quick to put one on demo as I was waiting for them for 3 months and right away I could hear a slight buzz when right up to the screen but it mostly sounded as if it was coming from the back and I couldn't really hear and substantial buzz. So I went ahead and bought one knowing if I got a buzzer I could easily return it.

After getting it all wall mounted and set up I sat down and was blasted by buzz, I was extremely disappointed that Samsung hadn't fixed it and upon further investigation it is shocking how directional the buzz is. If your sitting anywhere off the outside edge of the bezel you cant hear anything, if your sitting even slightly off center 8-10ft back its not bad but once you get right in the middle it will give you a headache after a few minutes, its just as loud as a xbox and trying to watch movies is terrible as any time there is a quite scene or dialog the buzzing is overwhelming

I then went back to our demo unit to see if that one did have as bad of a directional buzz but even with just the TV on and everything else off before the store opens I can't find a spot thats nearly as bad. I can't tell if the buzz is less because its in a room with sound deadening walls but I will be returning the one I have and picking up another in hopes they really are that different.

zakmichaels really hit the nail on the head with his description of the problem, I also used my Iphone decibel meter, probably not as accurate as the one he had but I noticed 4dB increase when it was in front of the TV. I did a test with a person slowly waving a small solid object in front of the TV and you can pin point where the buzz is emitting from and almost disappears when certain parts of the screen are covered.

On a side note I haven't seen any other 2010 buzzing Samsung's returned but did get 1 - 60PK550 LG returned due to loud buzzing. So I hope the buzzing units are few and far between as this came of the first shipment of the year and hopefully the ones we have now have a later manufacture date and newer parts, perhaps they were using left over 850 parts. I also checked the PN58C590 thats on demo and couldn't hear any buzz from it although I could hear some from the PN50C540.

For people going to see these TV's in stores make sure you aren't standing above the top of the TV when your listening for the buzz you probably won't hear it, its like flipping a light switch as your ear passes the top of the bezel when your sitting down.

I am not only disappointed in Samsung but as well as Panasonic for not offering the 5,000,000:1 - Infinite Black on any 58" TVs other than 3D models. I know they have a 54" 2D with the Infinite Black but I'm picky and want a 58" and 3D doesn't interest me.

Got my PN58C8000 about 5 days ago. It buzz alot... sitting about 10 to 12 feet away the buzz is loud but cant hear it when the sound is on. The buzz is very directional u sit a few feet off to the left or right or stand up and the buzz is gone. no sound coming from the back of the display. The sounds comes from a few spots on the front of the glass. I have a 42" Pioneer Plasma that is 6 years old and that thing does not make any noise compare to this Samsung. I am taking it back for a replacement and see if the new one makes the same sound.

I had a PN50B650 and it was also quiet as a church mouse.. No buzz what so ever.. I see alot of folks just posting their model number, but it would be more helpful if you guys also posted your build date along with the country it was assembled in (if available).. Some times two differant places can build the same TV or the same parts (if there is a need) for Samsung etc..

Well I did the exchange. No better. Maybe worse. There is one difference though. The B530 seemed to change loudness directly with screen brightness. The C540 changes loudness with screen content, but it's not obvious how brightness affects it. A black screen is sometimes quite loud.

Since I have owned 2 Panasonic and 1 LG plasma dating back to 04 and have never heard a "buzz"...I always thought it was either a myth, caused by something else, or my hearing wasn't sensitive enough. That is until a coworker got a Samsung plasma about 6 months ago (don't recall the model #) and complained about the buzzing. I told him I was skeptical but curious, and he invited me over to experience it for myself. Well...yes, his plasma does have a buzz. I didn't notice it right away, but when I moved closer and he turned down the sound I heard it clearly. Naturally, I went home and tested my plasmas for buzz...and thankfully they all passed. Even so, what I heard wasn't loud enough to bother me...but I can see why people with better hearing could be annoyed.

Hi all. I have been browsing this forum on and off for about a month before finally deciding to pick up a 58" C6400 over the weekend. I brought it home plugged it in and held my breath while I turned it on - F#$k it buzzes... so much that it gave my wife a headache. I didn't hear this at the store when I checked it out the demo model - might be the background noise. The unit is going back soon for a return.

One thing I also noticed on my unit was that the sheet metal in the back was slightly warped - like there wasn't enough tension when it was assembled. When I poke at it the metal it would "pop" out at a neighouring location. Anyone else with this problem?
