Question:

What should I do if my LED TV is making a high-pitched whistling sound, and how can I determine if there's an internal problem?

Answer:

Like all electronics, your LED TV might produce a slight hum, buzz, or whistle during operation or standby. To determine if there's an issue with your TV, follow these steps:

Turn down or mute the volume - This will help you better hear any noises coming from the TV.

Listen for the noise - Pay attention to whether you can still hear the high-pitched whistling sound even with the volume lowered or muted.

Have another person listen for the noise - Ask someone else to listen to the TV as well. If they can also hear the noise, it increases the likelihood that there's an issue with the TV itself.

If the noise doesn't disappear when the volume is muted and another person can also hear the noise, there is likely an internal problem with your TV. In this case, you'll need to have your TV serviced. Contact 1-800-SAMSUNG for further assistance.
