On every drive the spindle motor spins up so the laser can read the TOC. The PS3 is no different. Cleaning the Laser is not a cure for no spindle motor rotation. These type of faults are easy to identify on any deck (are you sure you repair systems or is it just a hobby?) But can have a complex cause.Disconnect the motor and connect a bench PSU to it or hook a battery across it to see if it spins...
