PS2 DVD Laser Adjustment

[downlo85]

I'm thinking about adjusting my DVD laser cause it's having trouble reading some DVD-R disks, but I don't have an oscilliscope or multimeter or anything like that.

Has anyone adjusted their DVD laser? If so, how much did you turn the DVD potentiometer?

Since I don't have a scope or multimeter I have to adjust via other methods and I'd like to have a rough idea of how much I should be adjusting it.

Thanks!
