Thanks, Kynan. Not sure if I want to disassemble too much on  
diagnosis yet, depending upon how difficult that is (I do have the  
disassembly docs).

To provide a little more detail, When I press the power button, it  
does spin up the disk and ring the chime every time. Then it goes no  
further, disk spinning, display blank and no disk head activity. I  
don't see any damage in the hinge wiring and the broken hinge didn't  
seem to affect or stress the wiring (it only had just cracked on one  
part; no misalignment). Jiggling the wiring while it was on and  
working didn't seem to affect anything.

Since the external display is also affected when it freezes up and  
scrambles the screen, I was starting to discount the display or  
display wiring. However, perhaps the glueing and clamping operation  
affected the wiring inside the display. If that's the case, I can  
probably just run it headless as a server or with an external display.
