I've NEVER seen anything like this!
PROBLEM:
I start it up my Powerbook and I get screen activity for about 1 second (see videos) and then it goes dim. You can still (barely) see the display.
STEPS TAKEN:

The screen fickers and goes to almost nothing... What is wrong with my PB?

It might be an expensive repair if it is that so a new computer would likely be a better option. The Macbooks and MB Pros are both much faster than the powerbooks.
That would be true if it was not displaying at all, but he mentioned it's displaying, but extremely dim.
Logic board problems can show graphics glitches and can randomly show the display. It also causes external displays to not work and the system usually crashes not long after booting when it gets bad. Usually the display goes off though and not just dim as you say.
The lack of feedback from the buttons suggests that the machine is crashing. A bad display would allow the machine to boot entirely and the keys should still be audible.
It needs to be taken for repair whatever it is. It doesn't seem like a user-repairable problem.
