A thing that might help you to use it better while it's dying ....
at the browser screen and the PS2 with no disc press triangle and choose "Unit". Press triangle again. Turn "Diagnosis" option on.
That will make the PS2 self adjust for the discs you put on the tray. If it's a USA v1 or V2 it will be even better because it will adjust both laser power and white cog automatically. Other models can adjust only the laser power automatically ....
