This maybe due to overheating of some Sort.
Try taking it out of where it is where theres a good flow of air.
Then try running a cd.
Try Putting in a Cleaning cd, this maybe a fault with the laser.

this player uses a philips mechanism, spindle motor failure is very common on these mechanisms, yours may be on its way out. take the lid off and insert a cd and if you can hear the laser trying to read the cd without it spinning, it's definately the spindle motor.

First I think you should turn your player on and wait 5 - 40 minutes before before you start liste3ning music.
because electrolytic capasitors may be little broken and those can repair themselves but it takes a while.

Good rule of thumb is that If you don't use every day an old device
then you should give to it every time a soft start . like I mentioned earlier
turn power on and wait.


Second try to play music cd which don't have any scratches and without any copyprotections

Third Disconnect power cable

Then open device and try to clean all dust.

Look for hairs and other difficult to see objects uselly
you find at least one hair inside old cd player.
If hair is around disk spindle it maybe difficult to
remove.

Check that cd-disk makes good contact so remove even tiniest dust and hairs
between cd-player and copact-disk. It may be called spindle or what ever but
still try to clean it with Isopropyl alcohol and remove dust and filth.

Check laserlens and is there some dryed liquid stains if there is try to remove those
with Isopropyl alcohol and swabs. Don't use any force and you can tear a top of swab little longer
(about one inch) and you get swabs which are much easier to use these kind of delicate cleanings.



Lubricate every moving part with lithiumgreese don't make any mess.

This last fix is for most desperate ones.
Connect the power cable and push eject and be carefull because
you can get fatal electric shock.
Disconect power cable. You can use extension cord which have on/off powerswitch.
You can see six tiny trim pots.
First take photo of those pots so you can undo all changes.

Change only one pot and only about 1/8 of turn. Turn power on and test if you make it worst or better.
If you think you fixed the problem that is not the case ... yet.
Then you have to make finall test and play a lot of music cd:s and after that you have fixed the problem.

Make notes which cd:s and what track your player don't play properly and use those
cd:s to testing those trimpot changes.
