no spindle rotation

Hi, I work on technics cd player model slp102, THE PROBLEM IS....... NO SPINDLE ROTATION.... The laser lens work ok, do the focus search, but no spindle rotation. I checked spindle motor , the motor is ok, but no voltage go at pin + . I changed an8377 ic close the spindle, but no effect. I checked the voltage on this ic , it look ok. I have no service manual.... for better check, SO do you have an idea? Thanks .. Richard......... rovni@videotron.ca
