My recently purchased Sharp LC46SE94U LCD HDTV continues to intermittently display its Channel Information window. It only displays when watching our satelite broadcasts (not during DVD viewing) and shows that we have mono sound even though I have the TV selected for stereo. By default, the TV should register the stereo broadcasts, but it only grudgingly flickers to show stereo reception, then defaults back to mono. I woul appreciate any info on how I can keep the window from popping up on its own and espacially if there is a way to verify if we are indeed getting stereo or mono sound input/output.
