Just got this TV New Years Day. First thing I noticed with it was a buzzing sound which I guess turned out to be the backlight. I figured out if I turn the backlight setting below 87 it starts to buzz but above 87, it's fine. I figured it was no big deal and everything was fine. Now however I might have a different problem. If the volume is down low, you can a hear a low static sound from the speakers. It's there watching TV and it's even there when I play my PS3 which is hooked up via a HDMI cable. The sound doesn't increase when I turn up the volume and during normal TV watching you may not even notice it. It also stops when I mute the TV. Just wondering if I should set up an appointment to have the TV looked at or not?
