Are you sure it's not just a coincidence? If you just bought it maybe you didn't notice it before now?

I wouldn't know what to do either, except try manually cleaning the lens with a fine brush and looking through a magnifier. Also perhaps lubing the bearings if they're accessible.

Your pickup is probably tired.

There are some adjustments that might improve things. But most require the use of a 'scope.

Please, don't tweak around various adjustments, because you might loose reference.

A new pickup should get you up and running. Its a KSS210A SONY type pickup. not very expensive.

Let me know how things turn out...
