Backlight high pitched noise: I've tried plugging the TV into a wall outlet vs. a surge protector.

I'm having the same type of noise problem with a 26" Samsung. It was like that straight out of the box. The backlight was set on 10 (in the Dynamic picture mode) I have to keep the backlight setting at 5 or below and then it's masked by the TV volume. On mute I can still hear it. Very annoying. I'll be contacting Samsung very soon.

I discovered that same hiss when my TV was connected to a DTV converter box, equipped with its own universal remote. I was able to eliminate the hiss by lowering the volume on the TV's remote. I use the converter boxes remote to power on and off the tv as well as change channels and raising and lowering the volume. Note that everytime the tv suffers a power interuption by either being disconnected or power outage, I have to again lower the tv volume (and raise the volume using the converter boxes remote

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.

This has not happened when I used mine. Most of my use has been with TV. Good luck in finding a solution to yours. Extraneous noises are very distracting.

I have a 5 bulb fixture hanging over my kitchen table. A high pitched whine comes from one socket. At first I thought it was the socket. I changed bulbs. Same noise. So it's a bad socket, not a noisy bulb. Changed the socket, noise gone.

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?

Unplug it, wait a minute or two and plug it back in. I had this problem as well and it was happening a lot, so I returned my tv for a LG...great move, no problems since.

That's kind of what I had. But it wasn't a steady buzz - more like a loud 60 Hz humm. I even tried to move it as far from the TV as I could. I was thinking there was some sort of interference, and separation might help. But no. Amazon is great about returns. This is first time I had a problem with a purchase.

Remember, this is to stop grounding faults so when you plug something like your computer sound card into your TV, you don't get that hum. You probably don't need it on most of your tv's.

I just had this problem and found this post after searching for a solution. I plugged my coaxial cable into my surge protector and bingo, problem solved. I am using component cables to connect my cable box to my HDTV. I think I'll exchange my box for an HDMI capable box and hopefully that'll solve my problem without using the surge protector.

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.

I have the same issue with my two-week old 42B450, as well. The plastic bezel makes faint crackling noises as the unit warms up (lasts for about 30 minutes). It is definitely the plastic bezel since I can duplicate the sound by pressing the bezel along the top edge of the TV. Another Amazon post said that they had the same issue and so they returned the TV for replacement and the second one did not make the sounds. Am curious if the Samsung rep mentioned above actually has a fix for the problem.Except for this issue, the TV is excellent in every way.

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

Yeh, I bought mine 10/15/08 and had the same problem.It turned out to be a ground loop between my Receiver and my Samsung TV.I put a two-prong "cheater" on the Samsung power plug and that fixed it.Not the best way, but the hum is gone.

I am sorry but I have not seen the problem you describe with my flat screen. It does not sound normal for the TV. Good luck.

I suggest you call the manufacturer for advice so that you do not damage the TV. Please let us know what advice was given for the good of mankind in case any of us get in the same fix.

Try putting a barrier between the audio or speaker cable to your power cables. Or don't let both cables, run side by side for it will create interference, such as distortion noise. Using a power conditioner helps a lot.
