Mine did that and it was the battery. They do have a shelf life. I replaced it, and it works great now. I got mine at BatteryMart.com and it is this one: 12 Volt 5 Ah F2 Terminal Sealed Lead Acid Battery Part# SLA-HR-1221W-F2. Hope that helps, good luck.

The battery has gone bad. You need to replace the large battery; then it will be fine. Battery lasts about 5 years.

I did not hear 60Hz hum or buzz when using my Fuze+. Many other inexpensive MP3 players (eg Panasonic, Cobe) have very conspicuous electronic noise from the unit processor (aka interrupt noise). I find the SanDisks Sansas better shielded from internal noise than cheapter products, but it is not perfect. AC hum hasn't been one of my complaints. Another idea you could try, if you happen to be in a high-noise area, is to get a length of wire, connect it to a metal coffee can and plug the wire into the ground outlet of a three-pronged outlet. That should create a Faraday cage which should absorb that 60Hz signal. I did not hear 60Hz hum or buzz when using my Fuze+.

Did you ever get an answer? Mine appears to be buzzing all the time too - I agree. Extremely annoying.

Not sure what sound you're experiencing, but it should be very quiet. There is a vague electrical hum if you were to get right up next to it, but that should be it.

I have a slight buzz from mine's as well, really noticeable when the volume is on a lower lever (anything below 15). From what I have read, this is fairly normal since a lot of energy is used to heat the plasma. Also, since I'm only about 7 feet away from my set, that might be part of the reason why I notice it. Did the samsung tech support cost a lot to come out to install the insulating material?

The buzzing is only present when the backlight is less than 10. I believe its the flourescent bulb buzzing similar to when typical flourescent bulbs are used with a dimmer. I haven't found the sound to be any louder than the fan/hard drive in my Tivo so I'm not worried about it.

My wife has a buzzing noise with her stock cable. We swapped it out and the noise disappeared.

I have bought 3 of these lock boxes and I cannot hear it at all, I put these safety boxes in a resturant so it is not really in a quiet environment, but I was having problems with employees messing with my camera system so I put the dvr in one box.

Yes, and it makes a buzzing sound but it's in closet so no big deal for me. I do like the unit. Also very heavy and well constructed. I like the input features.

Nope, more likely than not the buzzing is coming from your output source. Try playing audio from a different source and see what happens.

I am getting the same thing. It is a buzzing/loud humming noise. Anybody know if this is a defect or if something else can be creating this?

I have had the same experience (loud buzz, dropped signal). Very disappointing in a system of this cost. Is Nuforce intending on fixing this or is our only approach - as commented previously - to defeat the bluetooth and direct wire, which defeats the point of the system? With the advent of new bluetooth systems that have entered the market I would suggest that if Nuforce doesn't provide a fix to this problem that they will fail.

I figures out it was the disk drive; where you put CDs/DVDs into. I just put a piece of scotch tape over it, and no more buzzing!

You are supposed to press and HOLD the botton until you hear a buzzing noise

I just bought it & have Windows 7. It works fine except it has a hum that I can't get rid of. I've played with the gain button & the mic volume, but it's still there. Any suggestions?

All of what has already been said, AND, the headphone link is very noisy. Mine is anyway. Buzzes...hums... Same with two different inputs, two different power sources, no matter where it is placed. It's not an enviromentally induced noise...it's the converter.

Hearing such noises should be independent from using the KVM. Unless the extra value length now couples with more sources of noise
