You may have a damaged magnetic encoding on the inside of the Platter. Also may have been damaged by magnetic fields. You may be able to find another platter to test it with. These are beautiful tables but, not simple to repair. Even the pickup head setting is very critical so there are many possibilities, that can cause this. Where are you located?

Mine did the same. Check the distance of the magnetic pickup under the platter. Use a piece of printer paper to adjust it so it is just not touching. It may need a slight angle to the platter. Don't touch the inner platter. Fiddly but keep trying. Turn the platter by hand before switching on to make sure it isn't scraping the platter. Once adjusted tighten the screw and put a dab of paint or silicone on the screw.
Good luck

Kffern is correct, except a piece of printer paper is too close (depending on the quality of paper of course). You want .15-.18mm and you want to be sure the head is parallel to the strip on the platter. Too far away and it spins like crazy-too close and it will either rub or start to spin backwards on stop functions. Any automotive parts shop will have "feeler gauges" for adjusting spark plug gaps on cars-get the ones that are blade style and these thickness are standard on most of them.

You'll know its adjusted properly when you press stop and the platter comes to a stop with little to no additional movement. If you don't have a feeler gauge, take a piece of copier paper and cut it the width of the servo head. Fold the paper over once and use the folded piece of paper as the feeler gauge.

The feeler gauge should fit between the servo head and the platter and you should be able to remove it with a slight friction caused by the head and platter holding the paper. Don't adjust the head so the paper is difficult to remove. It should come out easily but you should feel a slight resistance.

If this does not fix the problem, remove the platter and inspect the inside of the platter where the servo head reads the platter. There should be a coating which is essentially a magnetic coating which holds recorded pulses that the servo head reads. This coating should not be damaged.

The servo can overcome small vertical scratches but any larger gaps will cause the turntable to not be able to lock into the speed pulses. The only way to fix a damaged platter is to find a replacement platter.

Good Luck,
