I purchased this TV from best buy a little over two years ago.
Within the last week it has started emitting a buzzing noise. I first noticed it when the TV was off. The noise is not always present.
If the TV is on and making the noise, turning it off will stop it, sometimes only for awhile.
If the TV is off and making the noise, I have to unplug the power cable to stop it.
I've read a few posts on the web saying this is common for aging samsung TVs. Can anyone help with a diagnosis and/or fix?
