I had tried some cheap one from frys and one with similar price range, they have humming noise too. Looks like this is 60HZ coming from power source, 120HZ, 60 hz AC current. These cheap one does not have good isolation and it will be problem with audio devices like radio. Will not work with my sharper image wireless headphone. Good that I read this comment before opening it, it is going back to walmart

I've never experienced that with mine in 3 years of use. I'd suggest unplugging it, waiting a minute and plugging it back in. If the beeping continues, I'd follow Bob W's advice and contact the seller. Good luck!

yeh the problem i'm having and i think the original poster is having is more of electronic beeping type noises rather than static, the static is probably just something to do with your hookup to the tv if it's fine on your computer and camera... but when i play back a video on my camera or computer i hear an annoying faint beeping sounding in the background

It sounds like a low humming. My son uses it every night, all night since I purchased it and still works great, almost a year now since he's had it

I notice zero AC hum or any whine. I would use this again. I will pass on stay clear of tranmittion over AC wiring S/R units---I think Black Box was the one I used. It has a delay and gets hot.good luck

I just started to notice that mine also makes the little humming sound. Kinda annoying

No, It's not normal. It's probably 60 (Hz) hum. Try reversing you AC plug, that should fix the problem 90% of the time. If that doesn't work try grounding the case.

I don't hear any noise or hum from any fan. The only thing that i didn't like is that when unplugged or the power goes out for any length of time there is a loud alarm until the power comes back on. Kinda annoying! but that is the only problem i have with it. Otherwise it is a great backup battery for my TV and cable box.

The only noise I hear is when you turn it on. Sometimes you will hear it interchange and sometimes you don't. If it has set off for a while it will make a loud click and hum but it goes away in a couple seconds. Other than that it does not make any sound that is noticeable.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

A hum that you can hear is normal. If it is loud, something is wrong. If it is noisy without a load connected, I would replace it. Are you sure you have not overloaded it?

i've never noticed a hum. The red LED is a bit distracting, but I just turn it away from my line of sight. Seems to work just fine overall.Note: I am not an audiophile and don't hear frequencies much above 10 kHz. Sometimes other people hear things that I don't. FYI.

Yes - mine squeals (ordered October 2014), I'm pretty sure it's an inductor or similar on the inside. Only occurs when a device is plugged in (so when the DC/DC inside is actually under load).

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

Oh no I'm sorry to hear you are having issues but I did not experience any issues. I literally just took it out of the box and plugged it in to the unit and it worked, no beeping or draining (so far!).

mine doesn't hum. I wish I could help. Maybe it is the model. I had one, that i loved, and one day, it just quit working. They didn't make that model anymore, and I had to cut the plug, and send it to them, and then they sent me the most similiar model. But I really loved my old one. It was beautiful. This one works great, but is not as aesthetically pleasing to the eye. :-(

Yes, mine makes a buzzing noise when it is charging. It is not very loud, at least in my garage, but I can hear it pretty clearly when I put my ear against the box.
