Spindle motor replacement for Sony MDS-JB930

#1 Ungelesener Beitragvon niekosss » Sonntag 3. Dezember 2017, 11:12

I am trying to revive a Sony MDS-JB930. The motor does not spin up most of the times, resulting in read error c13.
I tried to reanimate the spjndle motor with Kontakt 60/WL/61 but it did only work briefly. So, now am I am looking to replace the spindle motor, but I have a hard time to find the motor A-4672-474-A.
Are there any alternatives/other part numbers that can be used?

Ok, is the laser also compatible with the 930? Any suggestion where I can find new parts?

Is actually the spindle motor cause of the problems? Did you check if voltage is applied by the servo circuit while the motor fails to spin? If voltage is present, it may help to operate the motor for some time, maybe with an external power source while disconnected from the electronics. This removes oxide and dirt that may bepresent on the motor commutator or brushes after longer time of storage.
Another cause maybe that the inserted md is not always recognised due to laser problems and therefore the spindle motor voltage is not applied by the servo circuit.

Cheers,
Dirk
