We have inspected your PS4 system. There are problems with the mechanism and timing assembly in the Blu Ray drive. The sensors in the drive are completely misaligned and the drive gearing and components need to be correctly placed and adjusted for proper operation. In addition our technician found the motor controller circuitry electronics to have damage to the critical components to the married integrated circuit set. This is an unusual problem and most likely the result of previous repair attempts as the issues does not normally occur separately or along with the specific issues detected with the drive mechanicals.
