You need to re-adjust the mechanism. There should be an adjustment pot or two on the circuit board next to, or attached underneath, the CDM mechanism.
You'll need the service manual to achieve this properly. Perhaps someone else here has the manual you need.

This is a symptom of NO CLOCK.
Recheck all your soldering. Look for bad joints and solder bridges [shorts].
Which caps did you change ??Also did you change any cap values.??
Check voltages at power supply.

need service manual for philips cd471 or cdm4/11,I think,this problem is in motor drivers,motors socket has 4 contacts ,in socket is +--+ voltage about 6v,motor get two voltages and stay,no turn ,but it has voltages,one to left,second to right.help me!
I agree with the "No Clock" diagnosis.
It means that the master clock signal that controls everything in the CD player has been somehow disrupted and it not being received by the CDM.
