Hi guys
I try to solve a problem with my Teac CD player
There is some noise in the sound (permanent, no change, comes from speakers) I tried to record - Video
In addition, the spindle motor is not always able to start. Sometimes I have to help him with hand to start rotate
I replaced several capacitors who were with high ESR
Any assumptions will be evaluated.

Which model is your player?
If the spindle motor is a permanent magnet DC motor utilising brushes, then the commutator may be dirty and there are ways to clean the carbon or metal deposits out.

The model is PD H570
I had access to the brushes and tried with contact cleaner spray but without success ;//

I'll give your thread a nudge.
What do you mean by 'some noise in the sound'?
Do you mean something other than the speeded up warbling sound I hear on the video?
Or those random 'thumps'?

Spindle Motor.
Or, Low O/P from the Laser causing errors in the decoding.
But my money is on the Spindle Motor.

Its speed is normal, has a "thumps/pops/crack" sound several times per second. I think it is well heard in the video.
What checks can i make more?

If the noise has gradually developed and is getting worse, it may well be the spindle motor.
Noises which repeat at a regular rate can be caused by worn bearings, necessitating replacement of the spindle motor.
A loose spindle is another possible cause.
If the cause is not mechanical then adjustment of laser focus and tracking would be next on the list of of possible cures.
