Cd player fault quick fix any one?

You can do a few things to see what may happen.

1. Check the spindle height. The platters sometimes slip down the shaft, or the spindle motor bearing drops and the platter gets closer to the lens.
2. check that the spindle motor has not become lazy and "poling". give it a few spins. then try to read a disc again.
3. Clean the laser lens with a cotton wool bud moist with windex glass cleaner. Then "polish the lens with a dry one.
4. the spindle motor top bearing is worn and the payer mistracks as the armature moves about under the changing drive conditions. Makes the player mistrack and skip. More likely to happen at the start of a disc, because the disc is spinning fastest whilst reading the TOC.

A drop of light machine oil from a syringe oiler can help the bearing to spin an not produce the knock. Only a short term fix to give the motor a "lube". Once the oil leaches out of the worn bearing the problem will return. I have run motors immersed in an oil bath to rejuvenate them before... but better to replace it anyway if its suss at all. Good luck, You could bump my profile by giving me a "FixYa" rating for my sharing my "knowhow". Any problems check back with me here.
