Repair of Sony CDP-X777ES CD Player Transport
Advice Received
Clean and re-lube everything. Sony used a grease that turns to mortar over time. Gums up EVERYTHING.

Get all the old stuff off the gears and slides, re-apply lithium grease such as Lubrex. On motor shafts a drop of fine machine oil is OK.

Should work fine afterwards.
