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
?
