Default CD player skips

Hi

My Denon DCD3560 suddenly has got a strange behaviour.

It sounds like when a turntable plays scratched vinyls, the sound "jumps to the next groove". The display also jumps from let's say 2minutes 37 secs to 2 min 45 secs.
What may be the reason and is there a DIY repair trick for this?

Does this only occour near the end of an ablum? It could be that the disc vibrates more at it's edge and the laser is having trouble tracking it. How old is the machine? It might need the lense cleaning or sometimes the laser assembly replacing.

It is at least 8 years old, got it second hand from someone who had not used it for 3 years before I purchased it. I have had it for one year without problems, just started some days ago.
Happens in the first or middle or last tracks, no pattern.
Lens looks clean and shining, no visible dirt or dust.
I think I will let professionals look at it.

Some 3M laser head cleaning CDs might do the trick. It solves most of my situations like that. I normally let it play for about 4 minutes.

Clean the rod the laserunit slides on and the worm wheel as well and tip it slightly with silicone grease, it worked for me.

Yes! It has some little soft brushes on the playing side. This there are some instructions as the CD plays. The brushes brush the lens as the CD plays particular tracks.

How often is alignment required? I have heard about this before but never sent one in. One of my players is starting to skip on older disks.

I might give this a try myself.
