I turned on the receiver tonight and it was just a black screen and no sound. I hit the info button and the banner was blank with no info, not even the channel number. I hit guide and it was at channel 647-1 FSN Midwest HD. That is where I left it last night and there is a game on it right now. So, I hit channel down to 647 and the channel came in. Then I went back up to channel 647-1 and that channels was there. Everything seems fine at this point.
