you need to get a multimeater and measure the coils
then tell us how many ohms it is at, there are 2 coils, one for dvd and one for cd
i guess ure cd is orite if its working, but the dvd one may be broken
If the dvd one isnt broken then its somthing in ure ps2, if it is then u need another laser .... but there may be somthing wrong wiv ure ps2 to make em blow up
BTW, have u cheked the fuses on the mobo, and have u knocked off any capacitors / resistors ??
P.S. search the forum for how to measure coils, and the fuse diagrams
Edit. aha ure lucky i still have a v4 fuse diagram (make sure its this mobo tho - gh-012 - as the pic sez)
