Gutted is the word.

Does anyone know anything about these machines. I can change belts on these players but I don’t have the know how with the rest really, I could learn, but I don’t want to learn the hard way!

switched it on one day and the laser is ‘ticking’ and not finding disc?......

I’ve got one that no longer works. I don’t think the transports are very reliable. I had mine fixed in about 2007 and it broke down again in about 2014. The DAC part no longer works either. I would love to get it fixed but it isn’t very convenient to send things off for repair at the moment.

Yes. 
 

the other thing is, the day it happened, I thought I could smell motor. Took me back to when I was a kid and used to play with motors with batteries that where too powerful for them, and they would burn out. 
 

it supposedly had a new laser put on it last year, but I can’t be certain of this looking at it. I’ve taken the base panel off and the transport pcb to see if I could see any obstruction on the worm gear, but I can’t see anything.

I’m also very dubious of sending things anywhere.

I don’t want to have to eBay it spairs or repair, would break my heart. One of the best pieces of gear I’ve ever owned.

This is such a fabulous CDP. You need to  consult Marrantz or a very competent engineer. 

Bite the bullet with Marrantz if needs be.

There is a chap over on Pink Fish (Mike P) who repairs/upgrades older Phillips/Sony CDPs. I don’t know if he has experience of the CD7 but he’s worth talking to.

I thought about him, in Sheffield too I believe. I’ve contacted him before about the amp he revamped that I have. Can anyone pm me his number?

Tragic, a legendary player and Ken Ishiwata's finest probably. I had a Marantz CD17 mark2 for 16 years. It never misbehaved at all, but it has a different mechanism. I recently sold it to a fellow wammer  after I bought a Chord Qutest so I  just needed a good transport(I bought a Marantz ).

Good luck Craig, not far from you geographically....

Maybe could do worse than spend a couple of pounds on a new motor and swapping the worm gear over if the original is shot...
