I had the same problem. I unplugged the cable converter, waited a few seconds, then plugged it back in. When the box rebooted, the popping noise was gone!

SOURCE: Cracking noise SAMSUNG LCD TV

I wouldn't recommend doing anything yourself because you can easily make the problem worse. I would recommend calling samsung because it's been under a year and see if they cover the problem. If you open the tv, that could void the warranty so I would try samsung before doing anything to it.

SOURCE: my lcd tv makes a humming noise

Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

I had the same problem with my dell tv. It's the exact same one you have. It kept making noise at first, and then the sound just went out. I changed the speaker wires to a slightly stronger, thicker wire and now it works great!! I hope this works for you.

Why won't my NEC Versa P7300 microphone work?


Right-click on the little speaker in your tray (lower-right), and click "Recording devices". If it shows your Microphone as "Not plugged in", maybe you should connect the connection, and make sure you have it plugged in the correct place.

Loud noise from speakers when laptop closed/standby


Hi there.
Your microphone is on, and when you close the lid it is closer to the speaker. It needs
a loud noise (like closing the lid faster) and it enters into a feedback loop.
We need to find a way to make the microphone not play back.
Try left clicking on the speaker icon in the bottom right of the screen, and click playback
options. Here mute the microphone, and see if it solves your problem.

Good luck

Popping noise


Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television.
Can you help with this problem?
Thanks,
