bloke77, I doubt any of us will be able to help you with this. I think it best to go back where you bought it from.
I have made many mistakes in the past and just swallowed the loss and chalked it up to learning and experience. I would get a new turntable if I were you.
My guess is that the attractive field that keeps the platter centered is probably generated by an electro magnet which has stopped working for whatever reason. Permanent magnets are more expensive but they don't quit. You would have to take the table apart to figure it out. Since it is probably a total loss it cold not hurt to try. Maybe you will find a blown fuse or something easy to fix.
