By the way, if I ever said my sister and her husband's Samsung PN64D7000 doesn't buzz while my Samsung PN59D7000 does, I lied. Not intentionally, but I just plopped down in front of their TV, about 14 feet back. BAM! I wasn't even listening for it, and it hit me. At normal volume? Inaudible. Quiet moments? (during films and such) OH YEAH!

Oh, and my F8500 buzzes too, but it's insignificant in comparison to my D7000. Much better!
Seems to be on the brighter colours and especially whites that I notice the flicker.

But, adjusted the brightness settings to be a bit more dull which I didn't like to do, but haven't been noticing it as much. Will enable the Cin Smooth and see what happens.

Haven't called warranty yet, as been giving it time to wear in (hoping the buzzing reduces)...but I'm leaning towards the theory that newer models may not experience issues as much as the older with buzzing. Perhaps they finally tweaked the newer makes just right?

^ Given my two purchases on the D7000 and F8500, I will make my own conjecture and say this is probably correct. My F8500 buzzes significantly less (though it's still directional), and is rendered a non-issue in my eyes... well, in my ears.

When I investigated, it seemed like Samsung were trying to make the F8000 the same as the F8500 by way of colours only LCD.

I thought why would I pay $1000-$1500 more for that, when everyone just loves the F8500? And some buzzed, some didn't. So I took a gamble and sadly I got a buzzer.

However, after experiencing the advantages/disadvantages... even without the buzzing, I think I'd prefer a high-quality LCD. Enough to fork out the additional cash.

It's not even a comparison between the Samsung and the Panasonic. The Panasonic is much louder, so I was pleasantly surprised I didn't experience what some are in this thread. I sit 8 feet away for reference.
Yeah, that's cool.

I took a gamble too on my PS60F8500. What month was yours made in?

Seriously, happy for people to not have issues. I'm just stating mine. When spending several grand on something you love to watch, people deserve to buy eyes open. I have no ax to grind against plasmas, Samsung or what-have-you.

May 2013 is the build date on mine.
post #126 of 254
May 2013 build date. Just setup today.

Only can hear slight buzz from rear of panel if within a few inches.
Hardly any from front even if close up.
Unit is placed in a large built in wall bookshelf space with 12" depth behind it.


I am sensitive to hearing plasma buzz. Had a Pioneer Kuro I returned due to it a few years ago.
My replacement Pioneer has tiny buzz in rear of panel.

I am pretty happy with my luck here.
Awesome TV by the way.

I also am having buzzing issues my set was made in July. But it is tolerable only gets louder when really white scenes occur but at volume 8+ on my soundboard I cannot hear it is mostly coming from the front of the set right dead center should I change this set or with time is it going to get better it's not a defect right?
post #128 of 254
I am hearing buzzing strangely on dark grey screens or when white lettering is on the screen. I can understand why white buzzing happens but with grey? Any thoughts?

i hope this is true. mine is a september build and has the directional buzz right dead in the center at 12 feet away. hopefully it lessens over time i have about 120 hours on it so far. my dad says he cant hear it at all but has hearing problems in one ear.
post #130 of 254
My 64F8500 was delivered last week, manufactured in August. My wife and I do not hear any buzz thus far.
post #131 of 254
so im thinking of just exchanging it at bb for another one because i love the picture so much. I tried the ferrite cores and its still buzzing. i hear mounting it fixes the problem but i cant do that here.
post #132 of 254
My brand new Panasonic S60 (got it today) definitely buzzes, but after a while I can tune it out just like one would tune out any background noise. It's not super loud but it is loud enough to notice if you are looking for it.
post #133 of 254
Yep got a new 60 yesterday, and it's definitely buzzy. Very loud if you put your head right behind it particularly in the top/bottom/left/right corners, and it'll definitely catch my ear in a "what's that buzz?" kind of way periodically as I move the angle of my head from ~9 feet away.

I'm going to try to put a couple little pieces of sound-absorbing foam behind it, see if that fixes it. It's definitely louder that I'd expect out of a $3K TV.

sounds like a good idea let us know how it goes i might try that.

Since the new batch of sets came in Tuesday, & I went in to test another, I arranged to dump this angry beehive set for another from the dealers, in the next day or 2

I put an SPL meter up to that set & here are the differences

My beehive set: 1" from screen 80db; at 36" 64db; at 11-12ft 41db

Replacement set there also has a buzz, but: 1" from screen 64db; at 36" 51db; beyond that it drops off to below SPL reading capabilities (50db)

I will hear what happens when the replacement set is installed here at home...


UPDATE

Didn't get the exchange set - the owner tested the in-store "replacement" set again in their showroom.
& can hear the buzz from 10-11ft away when program content drops to dialog levels.

He said no point exchanging mine for another beehive

- he has contacted Samsung - they gave him their BS party line & cover story to avoid responsibility for their screw up...
"all plasma's buzz & some people have more sensitive ears than others."

As a result, he has dropped Samsung at the chain of 19 stores he owns...tongue.gif

BTW Really surprised Samsung posted my review on their site http://www.samsung.com/ca/consumer/tv-video/tv/plasma/PN60F8500AFXZC-reviews/consumer-reviews

As I have seen posts in forums that stated they censor negative reviews...

I put a 4' by 2' panel directly behind it and it didn't seem to make much difference. Guess I'll just have to try to get used to it. :-/

FINAL (?) UPDATE

I arranged to dump this angry beehive set for another from the dealers, in the next day or 2

However, as I previously reported, the owner wasn't satisfied with the 2nd in-store set, as a replacement for my buzzer,

I told him at this stage I am willing to try it anyway - so the swap occurred yesterday afternoon.


Well!! - this one is a keeper... biggrin.gif unless the buzzing gets louder, as some have reported

Not only is the buzzing less loud, it is also at a lower frequency,
- so unless I (& the Mrs ) strain to hear it, it is essentially quite.

Nice to watch a show like Real Time without the angry beehive disturbing the show!

Also, when the wife goes to bed & I turn down the volume on the AVR - I now cannot hear the buzzing


This has now jaded me (& my AV store owner friend) concerning Samsung products &
customer (dis)service mad.gif

Can you measure the frequency at all?
post #139 of 254
No oscilloscope available - I would have liked to do so...

But, during the exchange at home we had both sets switched on & the replacement was most definitely of a lower frequency buzz to me, wife & store employee.
as compared to the higher tone of buzz of the original set.

Think bumble bee buzz vs honey bee/mosquito buzz. biggrin.gif
post #140 of 254
You wouldn't need an oscillator, just a measurement microphone and some software. I'm just curious at what frequency these buzzers are, not having a buzzer myself.

yea i tried the sound absorbing foam and found its coming directly from the right side. The buzz is shooting straight out the front and the only way to stop the buzz is to put it right in front of the screen on the right side. I went ahead and exchanged it with bb and this one seems to be less buzzing. its still there but not as bad so now i can move on with my life and enjoy the picture lol

Hi,

 

Has anyone been able to solve the buzzing sound from the 64F8500? I have it and its definitely audible from 3-4 meters away.

 

I have tried varying degrees of covering the panel up but to no avail.

 

Please if someone has a good solution let me know.

 

Also, I just swapped my LED F8000 for the F8500 due to vertical banding however, while the F8500 doesn't have any vertical banding it does seem to be really bad at motion than the F8000. It is a huge difference between the 2 sets when I play games on it. For example when I play GTA5, everytime I pan the camera around, the world seems to lag with all the objects surrounding the central character showing a very very noticeable trail. I have tried using the motion judder cancellation option but that introduces so much artifacts its barely useable (standard doesnt seem to do anything while smooth introduces artifacts). Has anyone else got this problem or is this only for my set?

 

Thanks guys.

post #143 of 254
Got my 60" f8500 today and within 5 min after hooking it up i was on the web looking how to solve this buzzing issue. It is such a direct spot in front of the tv that i can really pick up on it. If i sit about 16" above center its gone, if i sit 16" below the center its gone. Shame it has to be noticeable right at proper viewing height. As long as i am above or below the horizontal axis i cant hear it at all. Mine was manufactured on Aug 17th 2013.
post #144 of 254
figured i'm pitch in another 2cents from my experience

originally I found the buzzing to be less than a non-issue, almost found it offensive to hear ppl say they buzzed. with some care I was able to hear buzzing, and concluded it wasn't enough to worry about, any audio washed it out anyway.

a couple days ago, I was redoing some audio adjustments, and i'd recently made some changes to my room to reduce noise, and while playing no audio content at all I did notice the buzzing again, this time with a periodic 'click' like you hear from a spark. again, not really an issue with audio content or any ambient noise. but, I also noticed that if I turn my head 90* and face one of my ears directly at the screen the buzzing gets like 100x louder. it's extremely obvious. I still find it mostly washes out with even minimal audio content playing, but I can certainly understand if anybody was hearing that while facing the screen, i'd be pissed as well.

I tried a bunch of stuff to see if I could get the loud buzzing without turning my head(plugging one ear, moving around the room, etc) but was unable to. so I really don't know what it matters. all I do know is that when I face the screen, it's near silent, and when I face the side wall it's quite obvious. so I guess there is something that makes it probably a lot more noticeable to some ppl. for what it's worth, I also noticed that while bright scenes sound louder than dark scenes when facing the tv, changing brightness has no affect when facing 90* from the tv. I have a fairly simple understanding of audio and interference(I teach waves in high school physics) and I can't explain these results at all.

were you using dejudder processing on the f8000? I've found the f8500 still has better 'native' motion than lcd's, but for whatever reason, Samsung seems to include WAY better processing on their lcd's than the plasmas. it's totally useless processing on the f8500 imo. I have an older d630, that while it's native motion is pretty terrible, i'm able to match performance with the f8500 by applying just a small amount of dejudder on the d630. I really wish Samsung would have used the same processing for their plasmas. maybe the small increments aren't as affective with plasma? all I know is the the lowest setting on the f8500 is way too much for me(I have it set to 1/10 on the d630) and there is no separate control for blur reduction vs judder reduction. I suspect the blur reduction is what is needed more(I have it set to 5/10 on the d630)

I even had my power filter hooked to the supply for the tv and still the sound. What you are describing above is exactly what im getting but right out of the box. I have had the tv less than 24hours and its going back. The store is more than happy to either give me a exact replacement or swap it for anything else i want. Shame to ditch the plasma and it good PQ reviews but im going to try the F800 instead.

mine hasn't changed, and it's still a non-issue FOR ME. i was just posting that mine does in fact buzz, but it's only perceptable under very precise, and unusual circumstances. just thought it was interesting, and could be evidence of why some ppl get 4 buzzers in a row, and others have never heard any of them buzz. i don't think it's a luck of the draw, i think some ppl just hear differently. i always thought i was pretty sensitive to the electrical buzz as i could always tell when a crt or even older lcd(i don't have new ones) or lights were on because i could hear the buzz. so plasmas were nothing special, the buzz was right in line with all the other electrical buzz i could hear. but when i turned my head, it was a totally different level, one that i could certainly see being annoying if i heard it all the time

When I took mine back yesterday for an exchange the guy knew exactly what I was talking about and said many have been returned for the same reason.
post #149 of 254
Pn60f8500 delivered today, horrible annoying buzzing when sitting in front or putting your ear behind the tv. So disappointed right now, I just returned a 60vt60 (which had no buzz) for this f8500 with buzzing and dings on the stand. I would have never have return the vt but I was having serious issues with glare and brightness levels in a bright room. I actually like the picture on the f8500 better, but this buzzing is driving me crazy much like my temporary tinnitus I had few years back did.

Going to exchange it tomorrow, probably gonna take a few days before the new one gets delivered though. I really hope when it gets here it isn't louder then this one.

RE: " for this f8500 with buzzing and dings on the stand"

Somebody else's return??

One wonders where the huge amount of these B]defective[/B] sets are ending up eh?? ... confused.gif
