You need to have a tape in place on the reals or it will stop.Hold the tape feeler spring in place and prevent it from moving forward it is located on the left side just remove the SONY stereo tapecoder cover and you see it

There is a cam with solidified grease on a lot of Sony Mechanisms. The deck need to be cleaned of the grease they used that solidifies and then a better grease such as Lubriplate 105 should be applied.
The Idlers need to be reconditioned as well. The Sony units can be labor intensive due to this required work but I do fix them when people want them done. I am in the Chicago area as Skywave Tape Deck Repair
What is probably happening is the take up reel is slipping or it could be a belt that moves the feed reel in reverse when you eject the tape. You might want to first put the VCR into rewind and see if it takes up the tape. If not then the belt is most probably the problem, or the rubber on the take up reel has glazed over and it is slipping.
I have fixed many of these and most all of the time it is that wheel or a bad or streached or glazed belt.
You do not list brand and model but it is typical that the belt replacement is missing the mark in that the reel rotation sensor is not detecting rotation of the reel table and therefore trying to go the other way. The reels have to be turning in play mode. If they do not auto stop or the reverse function thinks the tape is at end.
Any spares shop can make a match but otherwise this is for the round or square belts only You can fit a round belt in place of the square type it does not matter. I had some reel to reel machines and in desperation I went to a Hydraulic cylinder and pump spares shop and got an "o" ring of the correct length and thickness Remember that the new belt must be SLIGHTLY shorter to give grip on the pulleys. I have several units cassette and open reel that I was forced to fit this type and some some are running now over ten years everyday
The Capstan motor is just for the play speed regulation so it has nothing to do with the reel motors. You can have an open safety microswitch or maybe a bad relay. It is really hard to say without looking at the unit but I am sure it is repairable. Is the right dummy plug put in the back? This can stop all transport functions if it is out.
FF and Rewind are functions of the reels, not the capstans. If the reels fail to rotate in response to capstan-driven tape motion the unit will assume a broken tape or end of tape. I think you have a mechanical reel drive system failure. Take it to a shop for evaluation and correction.
The more detailed the description of the problem, the better for diagnosing the root cause. Thanks.
It sounds like you have a couple of problems. I'll address them as you have them numbered above.
1. Decks typically have belts to drive the various 'reel' mechanisms. Therefore, they can slip without breaking anything inside the machine or the tape. Your first symptom leads me in that direction.
2. That it migrated is mysterious, unless Sony is using a common motor to handle both decks' reel duties.
3. This symptom may have something to do with the root cause of both sides jamming...
Do the cassette well doors come off, say, for cleaning? Could they be dislodge? If so, they may have something to do with the jamming problems in # 1 and #2 as the doors play a part in positioning the cassette and holding it in place against the reel motor cogs. How do the doors operate with NO tape inserted?
Does it take excessive force to close the door only WITH a tape? make sure the tape is fully seated before closing the door. The capstans (directly below each reel cog) have to engage through the small holes at the lower edge of the cassette. They should be straight and clean. Any dirt or oxide on them will cause problems as these are what move the tape at the precise speed necessary for good playback or recording.
My hipshot recommendation, otherwise, is to look around inside the cassette wells very carefully for any foreign matter, debris, dust bunnies.
