A few months ago my PS2 Slim broke and I thought the laser burnt out so I just let it sit in my closet cause I did not want to buy a new one. I decided to spend the entire day today researching stuff about it and eventually took apart my ps2.
The problem was that when I turn it on and close the lid the laser arm will move to drive to read a disc but then make this horrible grinding noise. After I opened it up I noticed that the grinding noised was caused by that plastic thing that sits on top of the worm gear (golden screw on the right side that guides the laser arm up and down). What is happening is it moves down towards the spindle and the worm gear or w/e its called would spin super fast and the teeth of the plastic from the laser would grind against the grooves of the worm gear.
Normally, what I think is supposed to happen is the laser arm moves toward and backward from the spindle and for what ever reason it is getting stuck once it moves to the spindle and it cannot go backwards.
Do you know anyway to fix this?
