Marantz CC67 CD Player won't spin disk

Original Burnedfingers · 26th August 2009, 10:49 AM

Marantz 5 disk CD player won't spin disks. You can load it and it doesn't see the disks. Display says no disk. Any ideas?

How does it recognize a disc? Shouldn't it start turning the CD and if it can read something like the TOC it considers it a valid disc? So if it doesn't turn the disc, it never recognizes it.
I have a similar problem here with a Technics SL-PJ26A that I gotta look into. I suppose it's a mechanical fault. The first thing I'm gonny try is to look that the spindle motor isn't burned out.

Does the lens perform a focus search routine and move up and down 3 or more times when the tray is closed ?
If no you might have problems.
If yes, have you cleaned the lens.
Is the turntable free.
Has it failed of it's own accord or were you working or modding it ?
What is the optical unit in these.

And after that it's proper fault finding time. Measure ALL rails and make sure no safety resistors etc are open circuit.

Ok,

It failed on its own without help from me.

The lens moves up and down as I can hear it.

The turntable moves freely without a problem.

I changed the motor thinking it might be the problem. I had a known good

motor of the same part number.

I don't know what optical unit it has in it but will try to find out.

The laser assy is a CDM 12.1/15

I had one in a junk unit so I used it in the cc67 player and it works now.

thanks

So was the laser unit bad?

Good to here it's fixed.
If you are feeling really brave,
Stripdown/Clean of CDM12.4

I assume it had a problem of some sort. The motor that I put in worked when taken off the unit and having voltage applied to it. It would not work however on that particular sled. After I replaced the laser/motor sled everything worked as it should.

Thanks. As I don't have a spare unit, I'll try cleaning the heck out of that thing. I'll report back.
