Marantz CD6002 problems

Aledh · 8th February 2011, 09:06 PM

Hi guys. New here and hoping to get some answers to a problem I'm having with my Marantz CD6002.

I had an issue where, on inserting a disc, 'TOC reading' would appear on the display but nothing would happen, until a while later I would get an 'Error' message.

I opened the unit up and nothing was happening atall. Although different from the usual no disc error, I suspected the mechanism was at fault, so replaced the whole unit with a KSM213CCM mechanism with a brand new one off ebay. I removed the solder blob from the pickup and on the first try everything was fine.

However, after this, when inserting a disc, the CD tries to spin, but refuses to, and I get the same 'TOC reading' and then 'Error' displays. However, unlike before, if I nudge the CD by hand, it will spin, read the TOC and play, pause, skip etc perfectly fine.

Has anyone any suggestions as I dont fancy having to remove the case and nudge the CD everytime I want to listen to one!!

Any answers greatly appreciated!!

Assuming the new platter motor is not marginal(worth a try to give it a shot of silicone spray lubricant, in any case), you probably don't have a solid +8V power supply to the TA2125 chip(pins 23,14 & 2). Check for 8V dc & then check it has less than 0.5V ac ripple. If not, you likely have electrolytic caps going south in the supply.

Cheers fella. I'm ok with this sort of thing but not marvellous, so will have a go. Wouldn't know where I could get a wiring diagram for the CD6002 would you? Would help me out alot.

I downloaded it from FSM Download Directory | Service Manual and Repair Manuals, which is a very worthwile, very small cost weekly/monthly subscriber fee.
