Problem is no discs will read now. Once the chip was installed originals and backups wont read. I've done the psx1 and xbox chips this was the first of my ps2 tries. Do I need to adjust the laser? If so how? Also I've noticed with my chip on other website install pics there is a extra wire used as a jumper up by where the cdrom clip down is at. http://www.norcalmods.com/graphix/v9-infinity.jpg
Anyone know what this is for? On the matrix website it dosent have this jumper and the sx wire is located in different place.
Please help been working on this for the last 3 days soldering and re-soldering.
