    I've scoured the net for an answer to this, but no luck so far. On startup I get the chime and the Powerbook looks like it is starting up, but there is no pinwheel and no progress. I've left it for 1/2 hour and it stayed on the grey screen.

    The optical drive is acting funny as well- I could only boot from Diskwarrior (not Mac OSX 10.4 Install Disc), and when I did, the screen looked like a negative, with severe pixelation (it was not because of my Universal Access settings either).

    I've tried unplugging and removing the battery overnight, resetting PRAM several times, attempting to start in Verbose/Single User/Safe modes (none of which work), running Diskwarrior 4.0, starting from other startup disks (no luck). There is a new HD installed and it is ok according to Diskwarrior. The machine will load in Target Disc mode and Open Firmware mode, but that's it.

    I am at a loss, any suggestions? I'll try just about anything!

    Have you tried inserting your Mac OS X DVD and re installing?

    If that doesn't work, then it could be a dead logic board or bad RAM.

    My CD drive is being fickle and won't load my original OSX 10.4 disc, so I am not able to boot from it. I have another mac, should I try to reinstall 10.4 via Target Disk Mode from the other machine?

    Try

    Does it chime? Try holding down Shift+Cmnd+Opt+P+R until it chimes a total of 3x. Also in answer to your question about target disc mode, yes;
