JVC combo deck, DV and VHS, model SR-VS20U
Deck would not load tape.
We had a deck that would malfunction if anyone pressed in on the VHS tape on the right hand side. This would skew the load mechanism to jam. Just instruct the user to press inward with the tape at the center of the tape. The tape would also load properly if it was pushed in from the left. The tape carriage when pushed in from the right would cause the tape carriage to skew a bit. A metal tab along the left hand side would bind and stop the carriage from moving. I applied some special non migrating grease to three points that I found were rubbing along the top of the carriage assembly.
