If you are sure that you have fitted the capacitors correctly,there seems to be a problem with the cd decoder?

I think you will need expert help,to establish where the problem is.

Where abouts are you in the UK?

Good evening Nick,

sorry for delay.   I've just got out of work.

I'm normally in Watford but currently on a company project in Germany, returning home every 3 weeks or so.

I have an old BC 9000 dismantled for spares, which I gave-up-on because of  a dodgy cassette-drive.  Perhaps I could rescue the decoder out of the old CD drive ?  ( if I knew where to look )

Is this much of a job to transplant ??

Grateful thanks for reading & answering my post earlier

for now,  kindest regards

The later '9000 and early '9500 shared cd decoder and servo modules,but check that your decoder modules are the same before swapping.Also double check that the thin ribbon cable between the laser assembly  and the servo board is securely seated and locked into the socket on the servo board.Also check for stray cables impeding the travel of the swinging laser arm.

Regards,

Nick

Hello again Nick,

I have meanwhile checked my documentation.  Is Board No. 31  the CD decoder ?  (as in the BC 9500)

If yes, Could you tell me which components to replace or whether I should do the whole board. ??

Looking forward to your advice

Yes,it's in the same position on both sets.Try your spare decoder first,if it's identical.If this overcomes the problem,fine.Oherwise,I'm afraid testing to component level will be required,to locate the culprit.

Regards,

Nick
