I've had a problem with my LG 42CS560 LCD TV for a little while because of a scratching/buzzing sound during gameplay. I'm playing a PS3. The sound doesn't happen when I have the TV muted. Example of what happens in The Last of Us: whenever a loud sound happens in-game the scratching/buzz sound will happen briefly. Jumping to the ground from a ledge, gunshots, voice over in cutscenes etc. It seems to get worse when the volume is higher.
Anyone know what this is?
