Question about Samsung Televison & Video
Tv hums/buzzes even when tv is muted. Almost sounds like a vibration type noise but nothing I've checked is loose. Also, no sound bars connected to tv

I had the same problem with the same model.
The solution was to replace a capacitor, C622, which is located near
a small blue rectangular plastic component.
This component is a relay that is controlled by C622. I paid $2.39 for
the part, $8.99 for S&H for a total of $11.38. This fixed my problem!

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.

Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck

Testimonial: "Quick response, i will check it out asap"
Had this problem as well. Ran through a laundry list of possible solutions. Finally found that the key is to increase the backlight (Access via [Menu] [Picture] ) to 100% and the noise goes away. If this is bad for the life of the backlight, just pray the backlight burns out inside year 1 while the warranty is still valid!
