Grey Screen Boot, Open Firmware

본문:

Hello,

A few years ago my powerbook g4's logic board fried and I kept it in a drawer until a few days ago when I bought a used 1.5Ghz Logic Board and replaced it. Now the computer will boot but I only get a grey screen. I've searched a lot around and the best I could find was this: http://hintsforums.macworld.com/showthread.php?t=77999

that guy has my same problem. It seem though that everything is working fine but I'm not getting anything on the display (except for grey). I can get into Open-Firmware but I'm typing blindly. Does anyone know why this happens and how to fix it?

I have tried

- Reset PRAM, NVRAM

- Won't seem to boot off a CD (with c held down)

기기:

PowerBook G4 Aluminum 12" 1-1.5 GHz
