It's a problem on most sets im sure just not noticeable especially since most use AVR out the box.
As far as the tape how long do you cut when placing? For it to have any effect wouldn't you have to apply almost from one side of the frame to the other? Also is it just over the lower half where the speakers are or all over? imagine like you said it isn't pretty
I just played it by ear -- literally. First thing was the area around the speakers was buzzing -- taped every square inch in that immediate vicinity, then worked outward wherever I heard the vibration coming from. I had no assurance any of it would work since it seemed like part of the resonance was the panel vibrating against internal elements, and that was only going to be stopped if padded from the inside to keep the panel free of, or buffered from, whatever it contacted inside.
The tape square or rectangular dimensions were just based on available space (never covering any vents of screws), some sense of symmetry, and got more spaced out the further from the speakers I got. In the end, I did tape up some places toward the top -- it is a very loose panel after all (meaning you can easily bounce it back and forth just by touching it). Probably 8-10 areas taped up with 6-7 foam pads taped into them.
End result was that the buzzing and vibration almost entirely gone, with very robust sound. Occasionally with a particularly strong resonant frequency, I can still barely detect it. Some soundtracks worse than others for this. INCEPTION had that trigger frequency almost all the way through, but a good test of what is happening on your set would be to put on the closing credits if you have the blu-ray, go to the back of the set, listen and just press various areas with your fingers or a hand-held foam pad -- this should demonstrate where it is vibrating and what would cure it.
As I say, I did this to see if it worked. It did, so there is no cause (if I am not going to consider this a reason to return the set) to remove it or do anything different until such time as I might buy a soundbar. Even then, I might not take the stuff off -- there is no real compelling reason to do so -- I'm only satisfying myself and don't have to even look at what I've done, so the sound improvement works for me, even though generally speaking, it is sad to have to resort to this. My thought is that Samsung is trying to save on materials -- make the sets cheaper, as the price drops, and that would be fair enough I suppose. Plus they had quite a bit more venting in this years versus last (which did not have this panel problem).
I don't know, you could, I suppose, just regard these sets as coming with no usable speakers at all, with aftermarket soundbar a strict necessity, but I've really got no convenient place for all that jazz, plus extra wiring, etc. -- have not gotten around to those considerations, in any event...
