My cd player got hiccups when playing cd,or don't read the cd online hear clicking sounds.
I have cleaned the laser with IPA ging wellicht for a few days and nog this again.
Solution?
Bad laser?
Is it possible to change the laser by me?
Someone done this before.
Other options?
Regards
DICK

Welcome to the forum! Here's the subject: https://www.radiomuseum.org/r/sony_compact_disc_player_cdp_c.html
Just to clarify:
Do you get skipping back and forward of the music when the CD is playing?
And sometimes the disc does not play at all, and you hear clicking sounds instead?
There are other options to consider before resorting to changing the laser.

Skipping could be due to a mechanical problem: Check all moving parts are free to move and are not misaligned. Inspect tracks and gears for signs of wear, damage, dirt or dried up lubrication. Check drive belts are not slipping. To perform these checks you will likely have to remove the optical deck from the chassis by removing its mounting screws.
A laser failure is the last thing you should assume (unless you bought the machine used and you know the previous owner abused it by cranking up the laser power to try to fix a problem).
You were given good advice to check other mechanical areas (worn out brushes on disc motor, broken teeth on gears, gummed up lubricants, old/worn-out belts, dusty/dirty mechanics, etc.).
Also check for broken flex cables connecting the laser assembly to control board.
Search for thread by Mooly on his Sony CDP.
Not the same model machine but the diagnostic techniques will be helpful.

It's been around a LONG time and contains great stuff.
Good luck!

Common problem with laser diodes getting weaker with age. Some recommended fixes are increasing current to it - there are small potentiometers that you can adjust. It's not always an easy process though, and you can risk burning the diode with too much current. There are videos on YT.
Cleaning the lens helps a few days and then starting the problems again, also cleaning and greasing of the laser track.
I used IPA to clean the lens (recommended bij google) and grease the track with wd40.
I read overhere that wd40 is not a good grease option, so what can i use ?
And can I clean the track with a soft tip or have I use something solvend to remove all the old grease or dirt?
I bought a old player second hand so I have no idea of the maintenance during the years.
It comes from a pub including filled with cd's
The music skips sometimes a few seconds back and starting over again, and now some disc not read and plays no music , but the display gives sometimes the track number or the title of the song. hearing ticking sounds from the unit.
So clean all again ? changing drive belts, (hard to reach them , must remove parts of the laserblok)
Thanks for all the tips and info

You should not apply lubrication where no lubrication was present before. Clean tracks with IPA and cotton buds. Do not apply WD40 anywhere in the mechanism.
If the machine came from a pub when smoking was permitted then no doubt the mechanism is gummed up with the tar contained in cigarette smoke and may be beyond rescue!
Other potential causes are described in miloyd1's link and include a dirty "mirror" that is associated with the lens and a spindle motor (the motor that rotates the CD) that has unwanted play in its bearings or that has dirty brushes and commutator.

Don't even lubricate the track from the laser?
Or can I put there some oil?
Removed ther old grease already
What can I use?
Sewing machine oil or likewise or just cleaning?

Lubricate the track only if it was lubricated before you cleaned it. Some parts of the mechanism may be intended to run dry.
Use a white lithium grease or a silicone-based grease on parts that were previously greased, so as not to damage plastic parts.

Failure to read the TOC (Table of Contents) of the disc can be due to a failing spindle motor.
Here's something that worked for me when my Technics CD player failed to read the TOC:
If the CD spindle motor is a DC motor, its commutator and metal brushes may be dirty and you may clean them as follows:
Disconnect both motor wires completely from the circuit board and power the motor directly for a few seconds in each direction from a 9V battery or DC power supply. This may clean out any contamination from the brushes and commutator.
If this doesn't work then squirt a little contact cleaner into the ventilation holes near the motor connections and repeat the above procedure.

"Cleaning the turning mirror is nearly as important as cleaning the lens (especially for Sony pickups apparently since it is relatively exposed)."
You'll find the above quote under "Troubleshooting Guide" -"General inspection, cleaning and lubrication" in the link: https://www.repairfaq.org/sam/cdfaq.htm#cditrbchr
Here are the edited instructions on how to clean the turning mirror or prism on a Sony pickup:
"First, remove the black protective cover by prying the clips out on either side. Use a cotton bud stick stick to GENTLY lift up on the lens assembly taking care not to damage any of the fine wires. Blow out any dust using an air bulb. There will be just enough room to get a cotton bud, wetted with IPA, in between the lens and mirror. Note: The turning mirror is not silvered so don't expect a normal mirror appearance - it looks just like a piece of glass."

Just put the power on and inserted one cd , its spin's around 30 seconds with clicking sounds and the the display saying no disc.
Is this another problem or becomes the problem more serious?
Is this a sign the laser did not read cd's anymore?

Problems often change and manifest themselves in different ways while you are troubleshooting.
Not reading the disc as you describe may be down to a faulty spindle motor. Attempt to clean the brushes and commutator as instructed above. I would eliminate all possible mechanical causes before suspecting the laser.
Regarding the "burn marks", I can't really comment on those from this distance. However, I suggest you examine the electrical components underneath those areas for any signs of overheating.

Problem for now solved , turning potmeter from the laser a bit anti clockwise.
Plays again now.
Plays again now.
Can i instead a kss 213c laser instead a kss 213b laser? Or geven this problems?
The c type is already adjusted and the b type must be adjusted aftershave installation?
Is it ture after installation to remove a solderpoint
Someone done this before?
Someone changed the laser from this type cd changer?
