Hello, I have two different VCRs with the same problem.
1) The Sharp VCR takes the cassette and when I press play it spins the drum over the tape for 3 seconds and then stops and goes into standby mode. all rubber bands are intact. visually nothing is broken. cassette rewind works in both directions. cassette ejection and cassette ejection works fine.
2) Sony VCR. correctly accepts and ejects the cassette. rubber bands are ok. When I press play the same thing happens. but rewind does not work, although the motor is working and returns the film to its original position when removed.

How can I repair them?
