Wouldn't the processor have to be running for the HW test CD to run at all? As well as at least a portion of VRAM be functional for video to be displayed? Is this HW Test CD for the specific model PowerBook in question?

I got my hands on a Hardware Test CD ... (well, found it in my junk pile ! I never used it before !) To all test:
Airport No device found Logic Board No device found Mass Storage No device found Memory No device found Modem No device found Video RAM No device found
Now, I was pretty sure that I needed a new processor daughtercard, but
shouldn't it find some stuff ??
When I click on details, I can see the RAM at 320Mb, the hard drive at
6 gigs ... and the video card, rage 128 at ... 0Mb !!
That's strange ? or the VRAM is also on the daughtercard ?
I also put it in Firewire target mode and can see the hard drive. ran
a test on it, looks good.
Also, before I put in another processor, I want to make sure because I
can smell some burned plastic coming out of the powerbook. Will I fry
another card if I put it like that ? Is there anything I can do to
check so I would not fry the replacement ?
Maybe the application you use on the CD needs a running processor in order
to query the system for installed components? In any case, if you need a new
processor daughtercard, does it mean the current one doesn't work? If so,
how can you run the tests?
If you smell burned plastic, then there is almost certainly something
shorted out. Could be the AC/Sound board or the logicboard. It's hard to
tell. That's the kind of things that only a skilled technician would be able
to diagnose. You could check with PowerBookMedic I think in Toronto. I think
they do troubleshooting for reasonable rates.
