You could also try to adjust the potmeters that set the current strength flowing thru the lens coils. If you make the potmeter's resistance 5-10% lower than what it is currently it will probably be more than enough to read your DVD discs. You have to take apart the PS2, then unscrew the 4 screws on top of the disc drive. Also eject the tray before you unscrew the 4 top screws from the drive. Then take the rails out (the laser head rests on them) and turn the laser head over. You will see 2 small pots in there. Maybe they have a cd / dvd text written below them, maybe not - the thing is one of the adjusts the current for reading cds the other for dvds. If you want to make sure all is good, measure their current values with a multimeter, and write it down. Then subtract 5% first from both of them, adjust, measure and put everything all together. It should work. If not repeat and subtract an other 5%. You should not lower the value by more than 15-20% as that would almost immediately kill the laser.

If you make the resistance of the potentiometer 5-10% lower than what it currently is it will probably be more than enough to read your DVD discs. You have to take apart the PS2 then unscrew the 4 screws on top of the disc drive (fat models only). Take heed of ejecting the tray before unscrewing the 4 top screws off of the drive. Then take the rails out (the laser head rests on them) and turn the laser head over. You will see 2 small pots in there. Maybe they have a cd / dvd text written near them or maybe not - the thing is one of them adjusts the current for reading cd discs the other is for dvd discs. If you want to make sure all is good then measure their current values with a multimeter and take note of it. Then subtract 5% first from both of them, adjust, measure and put everything all together. I think the screw needs to be turned anti-clockwise to lower the value. It should work; but if it does not then repeat and subtract an other 5%. You should not lower the value by more than 15-20% as that would almost immediately kill the laser very .
