ps2 troubleshoot....

[eatme]

well, i found the troubleshooter guide.. after making some tests with booting procedures i found out that all my ps1 originals/backups play fine and also my ps2 cd base originals/backups... So my problem is dvd only related, which means that i will have to open it and clean lazer (since i cant find my cd cleaner) and if that fails verify for W and R wires to see if they came up loose, then recalibrate.. But i read that re-calibrate is a complex process, but i know i can do it... i dont think that is a bad laser since this particular unit doesnt have that much use.... can u direct me to a how to calibrate the ps2 laser?? tnx in advance...
