The research I've done led me to fell that it could be the Power
Manager, so I reset that too, to no avail. The issue is not likely
with the screen itself, since I've held down the option key to check
to make sure that the Startup Disk was properly set and the screen
would briefly show the startup drive and the arrow button, but then
would go away before I could even move the cursor to respond. Also, in
running the PB in Target Disk Mode, you could see the yellow Target
Disk mode symbol briefly on the screen before the return to gray.
The PB makes noises as though the drive is being accessed, but nothing
happens beyond the gray screen. Are there any recommendations which
might help me to identify and resolve this issue?
Thanks much for any help!

What about starting up from CD or DVD? And do you have a TechTools disc?

I'd take a shot at that. Further, I always stress the importance of a decent
external hard disk ... and now you have an excuse to get one. Make it
bootable, and see if you can boot from it.
- Command+v: Start in verbose mode
- x: Force startup (whatever the heck that is)
- t: FireWire target disk mode
- Option+Command+Shift_Delete: seek a different startup volume (as in
your new external drive)
- r: Force screen reset
- Shift: Safe mode
- Option+Command+p+r: Reset parameter RAM

I'm a strong advocate of having a bootable clone of my regularly booted hard
drive. Such a clone is easily created and maintained by SuperDuper! -- I
recommend paying the $30 so that you can do the so-called "smart backups"
which only take a few minutes to bring the clone into synch with the
regularly booted drive. I hate to think of the times my, er, uh, "sitter" has
been saved because of that clone.

If you can't even boot from the install disks, it's probably hardware
related. If you've zapped the PRAM, try removing RAM and attempt to see
if it boots with one stick and then try the other, if you have more than
1 stick of RAM. If not, try to get some from a local store to try it out.
Could also be a display issue if you were able to do so much via TDM.
Don't forget to ground yourself and turn your computer off and/or unplug
it from the mains before removing RAM, just in case you didn't know.
HTH
Who cares? As long as it works......
Thanks again for all of the suggestions and for your time!

Glad to hear it.
