The television, or any device with electricity running through it, is going to make some noise. If the noise is a new addition, and you feel it requires service, feel free to call 800-SAMSUNG.
Some noise, paritcularly if you're next to it with no volume is considered normal, however if it bothers you, then it's a good idea to get it inspected.
When I turned on my tv the otherday I sttod close to is and heard a high pitched noise. It is not noticably from where I sit but if I am about 1/2 foot away and no sound is on I hear it. Anyone else notice this or can you check if you have the same issue as I do.
The souns needs to be off and you should be close to the unit as I said.
Thansk for checking.
