I got Cyrus dAD 1 cd player on repair , and it is behaveour is strange.
I replace old laser pick up with new one , to see it is maybe problem with him , but when I put CD in drawer CD starts to spin but player don´t recognise cd.
The only component wich can make any problems electronically is SAA7378GP or maybe ext. crystal oscillator. All voltages forom PS are regular.
As I can see all features works , pick up and focus lenses are moveing
SAA7378 is digital servo processor and cd decoder (CD7).
Anyone got some idea on this problem
?

I'll move you query to Digital so it will get some more attention.
Regarding your problem, could it be the spindle motor? What transport is in there?

It is the CDM12.1 transport.
What safety jumper? I replace only laser pick up , not whole mech.
Spindle motor is OK , he spins disc normally , but there is no track read out, player acts like there is no cd after 30 scounds of read out trying
