thanks for the insight.. I removed all cd/dvd controller lines and the chip works in PS1 mode. Now, why is it that when I connect the CD/DVD lines it won't work? I kept them as short as possible, no shorts either.. What else can I do?

In the past, when I cross the pads or legs on the cd/dvd controller, on power the PS2 will not show any video or audio. Just check your points again. You've prove that if you desolder those points your PS2 works. To test PS1 backup games, all you need is power, ground, reset, and the SCEX line. If it works then your modchip is good. That's my two cent for you.
