The fact that you hear a chime indicates that the CPU (and some
memory?) is okay, since I believe it takes the CPU to make the chime.
Try holding down
when rebooting. (The command key is the one with the apple) This resets
the PRAM. If that does not work: You may have a damaged the monitor or
the video card. Try restarting while holding down
which places you in OpenFirmware, after doing system checks. You won't
see anything if your video is dead, but after some time (30 sec), type
"reset-all" and press enter. This should restart the machine, and you
should hear a chime, which will indicate that it *is* just the video
that is dead.
If this is the case, and you determine that you've damaged the on-board
video by trying another monitor, then the computer is still useable.
You can use another video card, or use it headless via serial console.
