This is my secondary PS2 so I'll take the risk.Swapping and running burns will kill your laser. My PS2 is on life support with FreeMCBoot.
Its working perfectly, as the laser carriage moves when you press the power sensor. The laser alignment fails because there is no disc and the drive firmware puts the laser in park status. Just put a PS2 disk in there and press the power sensor, it'll get to spinning without any cover. Do not get hurt, as the disk spins really fast.I found out certain slims have different interiors than others and to my luck, my other one's third sensor is right out in the open. However, the drive still won't spin. On top of what's shown in the video, I wedged tape in that sliding mechanism on the cover. What am I doing wrong?
