Hi everyone,
I desperately need some help with adjusting tracking and focus gain.
I am stuck with procedure number 3, see attachment. Every time I follow this procedure in the correct order, the motor stops spinning and I cannot figure out what I am doing wrong?
Thank you in advance,
best regards

Hello anyone,
I have found another method. I performed the procedure according to www.ralph-toman.de (cd player repair).
I managed to set focus gain, tracking gain and focus offset correctly. But still, I am not really sure I have set the tracking offset correct. I wonder if I have the correct focus error measering point.
Because one cd is still skipping in the first 3 minutes.
I will try more cd's...and keep you posted...
Best regards

I've observed that vintage CD players (pre-1990) often skip more than machines made from 1995 up to the current time.
For example, machines that can play multiple types of disc (DVD,CD) often spin a CD at 2 or 3 times the speed of vintage CD-only machines. I believe this gives them a chance to re-read bad spots multiple times. Unfortunately this capability does not exist in pre-1990 machines.
When I run across a vintage CD player which is skipping on a specific track I usually find that the disc has a significant smudge or scratch in that area. Plastic polish of the type used to remove haze from car headlight lenses is pretty effective on discs. I have succeeded at "repairing" several scratched CD's to the point where the older machines will play them.
However I have learned that some pre-1990 CD players are simply unable to play burned discs (CD-R).

Thank you EB, for your explanation and tip!
I think you're right.
When I play a second hand cd on my Onkyo DX-7211 player, it skips several times. I noticed there are scratches on that cd.
I will look for headlight polish and see if i can "repair" that cd.
Newly bought cd's play perfectly.
The Onkyo cd player is based on a Sony drive unit.
Do you know if there is a difference between Sony or Philips drive units based players pre 1990 build?
Best regards
