Panasonic DVX100a VCR Problem

I'm having trouble with my DVX100a, when I try to play a tape in VCR mode an asterisk appears between "TC" and the actual timecode (ex. TC*00:41:24:17, which I'm guessing is to indicate a timecode break) for just a second, then the asterisk disappears and the timecode runs but I don't get any sound or video, just blue screen. I've tried several tapes and get the same thing, same with fast forwarding or rewinding to different parts of the tapes. When I tried to import into FCP Log&Capture, it gave me an error saying that there was no video.

It was capturing fine last week, but I'm trying to do capturing for a documentary I shot and I need the camera to cooperate. I bought the camera used and so I don't have the manual and don't know all the settings. Help please!
