Question by TYL3R: I got a new TV LCD for xmas and I hear a buzz come from the back vent?
Its the LG 42LK450 and I use it mostly to play games like final fantasy XIII-2 but when the screen gets brighter the buzz will get a little more noticeable and I can hear it more and when the screen gets less brighter it will be less noticeable? Are all TV’s meant to do that I never owned A HDTV before
