First check that the sled movement is absolutely free - that there is no

grease on the slides that has gone 'sticky'.

Could also be a gear with a missing tooth - I had a Sony Discman which
had that problem, about 20 minutes into a disc it would get stuck at one
spot and just keep repeating. The missing gear tooth was on the drive
which moved the optical pickup from the centre to the edge during play.

Quite so, I'd forgotton that one, but you will of course pick up that
problem when checking the sled for freedom of movement. Another fairly
common one that can cause the same problem, is a split in the nylon pinion
on the shaft of the sled motor. If you push the sled manually down the
slides, you can feel it go bump-bump-bump as the gears rotate. Nothing can
be done about that one, except to replace the pinion from a scrap deck.
