Picked up an SCD 777ES from a friend last year for 400, originally supposed to be 200 because he said it wasn't working. Tried it out, worked fine, hence the higher tag, with a 30 day return. Issue returned yesterday. Very slow read time and maybe a minute playing track one, never any deeper. Kept working it for day trying to "loosen" it up. Fortunately found this thread. Easily pulled the lid, then 5 screws holding a black cover revealing the plastic gears. Definitely seemed tight. Easily pulled the floppy washers and the 2 larger white gears. Rolled some fine sandpaper to open them up slightly. A little lube, all moved much smoother. Q tip and alcohol on lens while there. Up and running nicely in under an hour. Swapped in my Oppo 83SE for a listen while repairing, but glad to have the Sony back. Might try to track down those brass upgraded gears. Thanks for the good read and direction to look.
