Below is a 2012 PN60E8000 with the back off. It takes a sharp eye to notice the difference between this model and the 2013 PN60F8500.

Hint: Look bottom center for 2012 mount for base.

I am wondering if somebody could give me some input on the ARC option.I have Arc output on my AV receiver going into my ARC hdmi on the tv.The problem is: I lose Channel guide and Smart Hub channel jumping(hope I'm describing that right)options.It seems to switch me over to Hdmi 1 (ca/tv?)when trying to use them..Samsung support and Crutchfield support says that's normal,but I have a hard time buying there isn't a work-around.Anybody defeat this problem?

So sad, because the picture is beautiful.

Last day for me to decide whether to exchange for another or just moving over to the LED, F8000 or 65F7100.

Can you hear it while viewing material at normal audio levels or do you have to increase the volume to drown out the buzz?

Agreed, even though they flow down the same line none are alike. Just another human mystery. No one is perfect, therefor their are no perfect products, and there are no two products alike in any industry.

Of course at normal audio levels, when someone is speaking or there is music in the background of the movie, it does drown out the buzz. However, when someone speaks, they typically pause at some point (at the end of sentences perhaps, or the pause as the other person(s) is about to reply, then the buzz is certainly heard.
So, if there is a constant melody throughout the whole movie, the buzz is not as noticeable (yet most background music will be significantly lower than the spoken parts, so the buzz is certainly heard at normal listening levels)....however if the movie does not have a constant melody (which I don't know many movies that have constant sound effects or music), and you have your typical dialogue, then the buzz can be heard ever slightly at voice level, then pronounced during any pause between sentences or responses.

For Samsung to say, "Can buzz be heard at normal listening levels," is not a fair question, too many variables. If watching action scene in Avengers, then no you won't hear buzz, but any dialogue driven show or movie, yes, you will hear buzz many times during.

Also of note, you can't just stand behind the couch and declare, I hear no buzz. For me it is in the seated position on couch in either my seat or my wife's (13 feet from screen)

Standing above the tv, I hear no buzz, just they typical hum of a tv being on...but if I place my ear in front in that upper right corner, then I can hear the buzz.

**I purchased a Monster HDP 2500 High Definition PowerCenter which has power condtitioning supposedly, but no change to buzzing...even when this was the only electronic device in the area plugged in.

I believe the number of buzz cases is not nearly as high as in the past for Samsung, but nonetheless I must have received one of the 5% (or whatever percentage may buzz) that do.

The black bars that I referred to are those fillers to the left and right of 4x3 images when the TV is set for 16x9 display. Not artifacts.

My contrast is currently set at 95. I don't tweak the TV settings. We were very pleased right out of the box. I think that I changed that during break in and never changed it back. Full disclosure here: From reading the posts here I have begun to wonder how much better a professional calibration would make our PN60F8500 look. Have a Darblet 5000 and use Green 70. We think the quality our picture is fantastic -- very realistic!

All plasmas have a buzz, it is inherent to the technology. Samsung is trying to pose that question to try and determine if the buzz is either at normal plasma levels or an actual issue. If you can hear the buzz at your viewing position at normal volume levels and it is annoying to you I would have the unit exchanged if you are able to. If you want a TV that doesn't exhibit any buzzing you will need to change to LCD unfortunately.

Initially our F8500 had a pronounced buzz that could be heard from the bottom right at the seating position, there was a 2' wide by 1' long window at 15' out that was very bad. It has been 2 weeks now and while I can hear a normal plasma buzz if I am close to the F8500 with the volume muted it has gone away otherwise. As it stands the Dish Hopper fan makes more noise than the F8500.

Added: I forgot to mention that elevation does impact the plasma buzz, the higher up you are the more pronounced the buzz will be. If you have a unit that has a more pronounced buzz I would still recommend exchanging it rather than moving. wink.gif

I tend to make an analogy of a modern engine: Totally controlled by electronic brains, when it is first put together and run, it tunes itself. Things like timing, gas flow, tickover etc.
It does so because no two engines are exactly the same. After all the hundreds of pieces are put together to run as one, it will run like no other of it's kind. The stored values in the brain will be pretty much unique.

Think of our PDP TV's as being similar. All the parts, each one having an oh so slightly different tolerance. The phosphor reacting just a tiny bit differently to a certain voltage then the batch a week before for instance. Things like that.

That's why each unit requires individual attention to bring it to a standard that is the same for all.

I have a buzzer here myself, and am exchanging it once the company order in another (special order tv here)

It's a directional type buzz that's coming from the center of the screen. As per Lazyboy's post, I can't hear it if I stand at the TV, but once I'm at ear level, and 12 ft away on the couch,
there it is....

I had a technician from the store come to look at it, who said he couldn't hear anything rolleyes.gif It could be a hearing thing though, as I'm 31 and he'd be perhaps late 50's.

It's especially prominent on black screens, and in normal viewing it can still be heard. You'd have to crank up the volume more than you'd need to (but not by much) to drown it out.

I experimented with putting blankets behind the tv for a few minutes, to see if it was an acoustic issue, but it doesn't seem to help.

I'm particularly disappointed, as I sent back an E6500 for this exact buzzing. The budget LG I had before this didn't buzz at all.

If I wall mounted a good bit higher, I wouldn't hear it, but I like to look at the screen at eye level, not looking up.

If the next one buzzes, that's me done with Samsung and I'll be getting a VT60 (at least there are ways around the fan noise).

I really don't want to have to do that though, as the picture is bright and beautiful.

Note: Plasma displays do buzz sometimes it's somewhat normal for the technology, and the further you are above sea level the more this will be an issue. Some people are more susceptible to this issue as well, you might be one of those people. If you can hear this buzzing during normal viewing content and it's really bothering you may want to consider other display options. cool.gif

Agreed, and something I rarely hear talked about is what happened to your TV between the factory and your home.

My first civilian job was with an American TV manufacturer. Yes, not only were TVs once produced here but they were the best. Every morning and evening I would walk by the QC area and watch the new TVs come off the line. Randomly selected TVs were pulled off the line and run at much higher than normal voltage until they failed then they were fixed and retested until they failed again. So the engineers knew the two most likely components to fail in the TV. Those QC sets were fixed a final time and sold at greatly reduced price to employees. They were the most reliable TVs I have ever owned.

Sorry, taking too long to get to the point. In one corner of the QC area was a shaker table. A boxed TV right of the line was put on the shaker table and shaken for the equivalent of a train ride from coast to coast and back in a box car. It amazed me that any electronic equipment could stand that abuse but all the tested sets were expected to pass.

The point is your TV may have left the factory fine but it received a lot of rough handling before you turned it on for the first time. Some maybe a lot more than others. Samsung seems to pack their TVs really well but they can't control the abuse, both accidental and deliberate, that their TV are exposed to.

If I were to invest in a Samsung 64" 8500F plasma, what issues would I possibly have? I want to know if people are overall very happy
With the Samsung plasma or are the issues pretty bothersome?
I know there is no perfect High end HDTV.

since you can hear the buzz there are only a few options you have.

1. sit off center either direction or

2. mount it high on the wall to where your ears are level w/ the bottom of the panel.

if you cant or won't accommodate to either of those,you'll have to decide if its worth it to you to keep the set.

Not sure is this only happening to my set.. when I stand near to the TV and watch from the top with head bending down about 45 degree.... I cannot see picture at the bottom of the screen I only can see there is faded black color horizontal bar at the bottom of the screen... this is also happening on the reverse side meaning when I look the TV from the bottom to up, I can also see the black faded bar on the top of the screen..... however this is not an issue when viewing on the normal level but I remember my previous Panasonic plasma does not have this issue....

^It's the filter and is perfectly normal. The filter on this TV is actually very very good IMO.

if you cant or won't accommodate to either of those,you'll have to decide if its worth it to you to keep the set.
3. Buy a surround sound system wink.gif

What % of f8500 has the buzzing problem.
I have a Panasonic ZT60 with fan noise,
So I am trying to figure out if exchanging
The ZT60 for a F8500 is something I should
Consider. Love the picture quality of ZT60,
Just like it to be quieter.
How many have a quiet F8500?

Asking % is pointless IMO as you are asking a subset of a subset of the actual purchasing population. Much like with the ZT60 and fan noise you'll be taking a roll of the dice with Samsung and getting one that may or may not buzz. There are no garuntees that you will or will not get one. On top of the set itself there is individual sensitivity and room environment that adds to the equation as well.

I know. It's tough to figure out what exactly to do. No perfect high end TV.
Leaning towards keeping my ZT60. Picture is excellent. Just a fan noise problem when playing TV at a low volume.
Buzzing could be just as bad of an issue. A crap shoot! Just a matter of how much the fan noise bothers a person! Exchanging TV could end up having a worse problem.
When looking at high end TVs the ZT60 & F8500 stood out as the best!
