Have you guys done the update yet on your TVs? I don't know if it's a firmware update or software update but it takes about 30 minutes and your set has to be connected to the internet of course.

In post after post, some seem not to want to acknowledge (or realize) that there are 3
distinct buzzes with this set;
1) The front Directional Screen Buzz,
2) Rear Mesh Panel Buzz
3) "Normal" Plasma Buzz - the 3rd has nothing to do with what most
are talking about & the former 2 types can be heard by almost everyone
with normal hearing...
Unfortunately & sadly, the Rear Mesh Panel Buzz seems to be the only fixable one
Any "all plasmas buzz", "it's your too sensitive hearing" and other such ridiculous statements come right out of the mouths of Samsung CSR staff, trying to blow off complaints.
If one scans through the 20,000 plus posts in the 4 or 5 F8500 topics here at AVS, to get educated about their
pertinent issues, one will find this holds true
These issues are even posted on Samsung's own site - & the 60" has the most complaints & 51" the least.
It has even earned its own joke - "the panel buzz lottery" label. However, the last ~6 months seem to favour the 64" as quietest, but 51" has been discontinued.
It has been recently reported (yet to be established as concrete), that a recent firmware update has decreased The front Directional Screen Buzz,
But at the cost of brightness (one of this sets best features)
!!!!! POSSIBLE F8500 PLASMA BUZZ FIX !!!!
After about 4 months of putting up with an annoying audible low buzz on my replacement 60F8500,
& since I had to pull out the TV & component stands to install my Oppo 103D,
a friend came over to help, I decided to take it off the stand & raise the set up
a bit by putting it on the TV stand's built-in Vesa mount assembly.
Well!! after doing that, did it ever start to buzz VERY loud, like a warehouse flourecent
fixture's ballast going bad!! From the top left corner, when facing the rear, from my friend gripping that corner when moving the set.
This was a totally new buzz & from a new area.
!!!! THE FIX !!!!
So I went around the back metal panel, pushing with a finger or squeezing the bevel in/out/towards the panel, on different areas all around the back & I found out by doing that, I could get the buzzes to stop or I could actually create a new buzz or increase or decrease existing buzzes all around the back. I took a Philips screwdriver & loosened or tightened the screws, sometimes squeezing the bevel or metal cover or some combination of the two, or sometimes just backing the screw out then in without touching the set. I had to play around with that in different areas.
Sometimes when I loosened/tightened a screw, it would cause a buzz from an adjacent area. Some screws needed to be tightened more, some had to be backed off a bit.
!!!! THE RESULT !!!!
Any buzzes that are remaining, are so low, they are only heard with ear placed a few inches from set.
for the 1) The Front Directional Screen Buzz, which never changed & is still very annoying from time to time. (But not as bad as my 1st horribly loud set that was exchanged)
The current set got much worse (#1)) when I took of the stand & mounted it ~8" higher on the stand's mount.
I'm not surprised, as Samsung itself since ~2009 have offered a warranty kit with gaskets or plastic washers for their plasmas. (kit no longer supplied)
I came across many instances of this when researching my F8500 purchase - I had hoped I could get a good 60".
Not so... sadly
