My TBC 1000 seems to be having an issue. Once in a while it seems to lose sync entirely and will ruin the video signal. Intermittently while playing back tapes, the screen will flicker with some horizontal lines across like a poorly connected cable and sometimes it doesn't recover from this. Instead of a clear picture it will just turn really dark, and the picture will scan across the screen like H-sync knob is off. Not sure if I'm explaining it correctly. I'll try and grab a clip of it happening later.
Turning it off and back on will immediately restore the sync, and it will usually work fine for that tape, even restarted from the beginning. The problem isn't isolated to specific tapes or parts of video. Once it's been reset, I can play that same section, and even if it flickers it will move past it and continue to work.
I bought this equipment some time ago, and it's been sitting on a shelf powered up for a bit every few months. I keep all the equipment on a surge suppressor that I used to switch off power to it when I'm not using it, and that's plugged into a decent UPS. I haven't used it much in the past two years, but I don't remember it having this problem before.
This sound like any type of familiar failure, just bad tape, or something I can correct?
