Solved! Pioneer VSX-325 TV Input Suddenly C1 Rather than H

[qt05]

My Pioneer receiver has been working for the last year. Suddenly the TV input is displaying C1 or 01 instead of H. I reset the receiver and the Samsung smart TV. I made sure that the optic audio cable was properly installed on TV and receiver, and that it wasn't bumped out. There is no "signal select" button on my remote. I can't seem to get it to auto detect. We do not have a sat/cable box. We have multiple HDMI input for Blu ray, a game system, and a computer. The audio input works for each of them. I believe it has something to do with the fact we only use the TV input on the receiver to watch the smart TV apps such as netflix. Please help.

Fixed. It is supposed to be C1 because of the audio optic cable. Just reset TV and Receiver again.
