I recently upgraded my Digital Cable service (with Time Warner) to include 4 HD channels. This meant that I got a new Cable Box, the Scientific Atlanta 3100HD. Since getting that box, I've noticed that there is a yellowish tint on almost all of the people's skin when watching TV. It only does this on digital and analog cable channels, not HD channels. I have an Avia-Calibrated Sony WEGA 36" HD-ready set. The input is through S-Video, going through my Onkyo receiver and back to the TV to the "Video 1" input on my TV. This does not happen on any other video sources, DVD, PS2, XBox, GameCube, or HD. Does anyone know if this is a known problem with the Scientific Atlanta cable boxes? Or if the problem could be caused by something else? I'd love to find out, 'cause it's really bugging me.
