Pced

Hello MD fans and experts! Trying to live by the motto Repair, Reuse & Recycle I'm trying to restore my old MDS-JE700 deck I purchased in Japan in the 90's. I even have stacks of unrecorded discs. With the deck I had to replace the laser due to the well known issue of nylon fatigue and managed to find a replacement unit in Germany for a hundred AUD. I replaced it and now my discs don't spin. I can see the laser lens bobbing up and down trying to read the disc but since the disc is not spinning it's ejected after a while with a TOC reading error. Loading mechanism works fine and there are no other obvious faults. To test the spindle motor itself I disconnected the motor and tested it separately with a 9V battery and it runs fine. I don't know if my problem is mechanical or electrical. There are lots of micro switches on the SW board. There's also the possibility of some contact issue with one of the flat cables. I've tried to ring them from connector to connector with an ohm meter and couldn't find any broken circuits. The mechanics in this modell is the same as in the 530 and probably a lot of other models. So I'm asking the forum here in the hope that someone is still using MD's for any ideas on what to test next or if anyone can even pinpoint my problem. ATB // Per
