Has anyone experienced excessive buzzing noise when using the TV at an altitude of ~6500 ft.?

I am at ~1000 feet and my TV buzzes. I only notice it if I am directly in front of the TV at any distance away. Off axis the buzz nearly dissapears. Regardless, I don't typically notice it when watching anything at normal volume. I don't find it excessive. From what I have read, I understand this buzzing is inherent in plasma technology.

All 60" and 64" models of the f8500 buzz. Well worth it for the phenomenal picture quality

There is a buzz heard when directly in front of TV at any distance. It is NOT inherent in Plasma technology but specific to this model. To me it is extremely annoying. I heard it during normal programming at normal volumes. It is a design flaw in TV that has not been addressed and it is a total deal breaker for me. Your mileage may very but I'm not listening to that high pitched whiny noise on such an expensive television set.

I'm at 2700 feet and it buzzes, but you get used to it and can't hear it over shows.

Unsure of the highest. I live at 7000' and have not had any problems. My understanding is the previous altitude issues with plasmas has all but been eliminated.

Have not had that problem. Our TV is in the basement and isn't used a whole lot though - no issues as of yet. I suppose time will tell...

Not exactly in that condition but yes I have. For example when running a game but just in specific parts of the game like in the menu or something. I think the buzzing comes from the fans but not really sure.

No, thanks goodness, I've not experienced it having a buzzing sound. I know the annoying sound you are talking about because I getthat buzz from a different type fluorescent fixture in my laundry room.

When it is turned off it's completely silent. People complain about a buzzing. There is a SLIGHT buzz you can hear if the tv has no volume. Any volume drowns it out.

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.

The only noise you should hear is the drive spinning, I wouldn't classify that as a buzzing noise. There really shouldn't be any noticeable noise at all!! I've had for over two years and have used in some rough environments, no issues at all!

It sounds more like the signal source is the problem. If it was within the TV circuitry, all channels would be affected. ihave had no trouble with my TV and it stays at the top of the technical world.

Thank you! I had Samsung tech support come out - they put in insulating material and that reduced buzzing by oh 80%. I'm happy now.

No, the buzzing sound is always on, unless you are on mute. I had mine for a couple of months now and it seems to have gotten worse

I bought a 50" 8UK Pannasonic tv a few years back. It had the same problem. So I exchanged it for another one. It also buzzed, but less so, so I kept it. Today, 3(?) years later, it still buzzes - especially on white or bright scenes. I'm seriously considering one of the 42" Panasonic plasmas for my bedroom, but am leaning to an LCD because I really don't want any buzzing/background noise in that smaller room.

i have the same "buzzing" sound coming from the vent on the left rear side. not sure if its normal but im going to set up service call to confirm. *update* ive been tweaking the settings and the buzzing seems to go way down if you put the contrast on about 50%, thus throwing the picture quality off. ive decided im going to send this tv back and replace it with the samsung lcd.

I've had my PN50C550 for several weeks now and had no buzzing at all. I've been very happy with this TV.

I have a buzzing issue. Try it for two weeks and ended up sending it back. LOVE PQ of this TV though.

I have the same problem too. I just bought this LED 55 in for 2 months and it is making horrible buzzing sound. With the backlight setting to 10, the sound is very obvious, and it will get louder as I watch TV longer, like more than 1 hour.I bought service warranty with Frys, the technician came in and tried to replace the power supply because he thought it was the problem. Turn out the problem was not caused by the power supply but the TV itself he said.I just opened a ticket against Samsung, the Engineer will come over next week to take a look.
