CD Player is slightly skipping

We have just picked up a rather special Marantz Layla MR2020 for my daughter. The CD on occasion skips. It plays discs and advances tracks fine.

I was going to open it up and lubricate and replace the laser mechanism. Not sure which one it is, so will find out when I have it open.

Is there anything else that could be causing this issue?

Thanks, George
 
Theres a great thread over on Audio Karma with Dr Audio* where he goes through several steps for troubleshooting.

But off the top of my (less knowledgeable) head, cleaning the laser lens and cleaning and lubing the sled rails both do a lot of good for any CD player.

Also try several discs, as older ones can lose reflectivity and be harder to read.
