My C61K seems to be locked on 480P output even though under resolutions it says that my TV supports 720P, 1080i, and 1080P. I know this because my TV tells me the input resolution. I've unplugged it and rebooted, to no avail. Any suggestions?
Press and hold exit button down for 10 seconds. Banner should come up saying HD channels are back. Probably accidentally sat on the remote and deactivated HD. Had the same thing happen to me.
Actually I was just getting ready to update my post. I solved the video skipping problem by tightening my wall connection for the coax cable near the hs17. I guess it being loose was causing the problem.
