Test the repaired system

If possible, test on a known good system first.
Improving the read percentage: If you are not happy with the results, keep adjusting the motor. Repeat until you are happy with the passing read rate, or the motor doesn't spin.
If you see the Insert PlayStation CD-ROM screen, the motor is running slow. Adjust the speed to be faster.
Partially reassemble the system and test it. If it is sufficient, reassemble the system.
To test the read percentage, get a few known good games and see which ones load. A minimum of 5 test games is recommended. Only adjust the laser again after each full test is done.
If the game loads, test play the system for a few minutes to check the stability. Important: Some early revisions have FMV issues - THIS IS EXPECTED.
