Marantz CD63 II sig need help with fault

dynoPort · 2nd October 2009, 04:58 PM

Hi everyone, I bought this fairly cheaply on ebay because it has a fault.

Disc goes in but does not spin. I've had a look and I first thought a new CDM-12 mechanism was needed but not so sure now as I put a voltage across the drive motor and it spun fine! Could the power supply voltage to the motor be faulty? Doesn't seem likely to me. Or if the laser was faulty would the motor not turn because of it? Before I order a new laser mechanism.... any ideas?

Thanks.

Hi.

With the cover off, the first thing to check is laser output.
If the laser is not working, the disk will not spin.

In the dark, you can just see the laser if you look from the side.
When the sled is put in with no disk, the centre of the laser should move up and down and also red light should be visible.

A working laser is no guarantee however as the output may be weak.

It could very possibly be a duff laser, even if it is new.

There are a lot of Chinese made versions around which are C**P!

Send it back and say it is duff. Demand a refund.

Forum member ROWEMEISTER who is based inDoncaster is probably the best person to contact ... http://www.diyaudio.com/forums/members/fidelity-audio.html

I've read other threads here and a regular culprit seems to be the TDA1301T ?

part ref. XD01 (crystal) seems to have some brown gunge on top of it. This could be glue used to keep the rubber tube around it in place? could it be a sign of overheating - failure?

can you test a crystal?
