The second BB only had the 50B850. I felt along the top and back, it wasn't hot by any means. Slightly warm, I'd call it. The screen was also warm, but not hot to the touch. IMO, not a worry whatsoever.
I put my ear up to front and back, and could not detect any buzzing. But, it's tough to detect that sort of thing in a big box store.
All in all, an excellent set!
That's good to hear if you felt along the very top in the back and it wasn't too hot. I can only speak for my Best Buy, not everyone else's, but my Best Buy had their 850 on an end-cap running a Samsung demo, and it had a lot of black and dark scenes in it. So that will help the TV run cooler. Smart idea on Samsung's part. (Stupid idea to hire that sick and sadistic spawn of Satan Ozzy Osbourne to do their commercials if you ask me, but I guess they didn't.) The more whiter and brighter the content, the more heat the plasma will put out. Darker content will not require nearly as much juice.
If you are going to compare different sets in a store to check for relative levels of heat, do understand that a Samsung on an end-cap hooked up to a blu ray or running a dark Samsung demo is not the same set of conditions as other TV's tightly packed against the wall near dozens of other warm TV's with little air circulation behind them, running a different demo with a lot of white content.
So ideally you want to check for heat with TV's in the same area, running the exact same demo, using similar settings (movie mode or torch mode etc.) (ask the store employees or look to see if you can ascertain where the AC is blowing in as well).
Furthermore, like I discovered at my Sears, sometimes these 8 series and other high end TV's are on an end-cap hooked up to a blu ray and it's possible that when the movie ends (after lots of black
credits for 10 or 15 minutes which could help the TV cool down a bit) the blu ray player will just go back to the default menu for the blu ray. That's what happened at my local Sears. They had a blu ray of Remember the Titans, and the not very useful kids they have working there didn't even know this was a plasma, they thought it was a Luxia LED, because they hadn't even put up a price or tag or someone had torn it off, and it was sitting on a pretty dark menu screen, for who knows how long. They probably would have left it there all day long on that static screen had I not taken charge and restarted the movie just to spare the poor Sammy some IR/burn-in in its infancy.
By the way, my local Magnolia is a very high-end store. After all they do have a 103 inch Panny plasma when you first walk-in that must cost tens of thousands of dollars. Even these clowns don't know what they are doing. They always have the Luxia LED on dynamic, and they have their G10 on vivid everytime I go in there and it looks like crap. They had the two new Sammys right next to them on movie mode and one on cell light 6 and the other 7. Hmm...
In their high end section of TV's they had two identical 42 inch G10's hooked up to a blue ray of planet earth, and one of the TV's was calibrated and the other not to demonstrate the merits of such. The blu ray had ended and it was just sitting on a static screen with some credits with bright white lettering, and after fooling around in the store for 30-45 minutes I finally walked over to the front desk and told their useless overpaid employee (not exactly a kid like at Sears) that the blu ray was not playing anymore and their plasmas were just sitting there with a static screen for Lord knows how long.
Furthermore, blu ray movies often have nice thick black bars on the top and the bottom, so you are not going to get as much buzzing and as much heat with thick black bars, because that top and bottom portion of the screen will not be lit up.
So there are a lot of factors that go into how much power, heat, buzzing you will notice in a store, or for that matter your home.
All I can say is that I went into Video Only, they had a whole line of TV's all along several walls, far enough away from the wall so there was equally plenty of air-circulation for each of them, all running the same content, the NBA finals. I felt the LG, the Sammys, the Pannys etc. up and down the row, and the 860 was clearly the hottest of them all. Even noticeably hotter compared to the 5/6 series which have thicker cabinets.
