i have a new sharp aquos lc-32d62 1080p for the bedroom. when hooked up to the comcast digital box (i haven't upgraded to hd on the set yet, i'm already getting hammered for two other hd sets) the display reads "3 cable analog mono". the guy from sharp said i need to hook it up with audio video (red white yellow) to get stereo. i did and put the tv on input 1. does this make sense? he says playing thru coax only gives mono.
