When i try to film or watch a tape i previously shot, I get a self diagnosis code C:31:40:00. I opened the door and took out the tape and let it sit for an hour. No change unfortunately. Anything else I can try? I did get it to work for a while by blowing warm air into the cassette holder with a hair dryer. It's also chewing up my tapes. It's like its' trying ti get started but it can't quite make it.
