Q: How can I get a dead screen on an iBook to work

The procedure is a bit different for different models of iBooks, so use the proper instructions on the linked webpage for the model of iBook you have to try resetting the PMU.

Sep 24, 2012 10:29 PMby Ronda Wilson,Which exact iBook model is it?
You can choose from this list:

Which version of the operating system is it running now?
How much RAM is installed?
What kind of optical drive does it have? (CD-ROM, CD-RW, DVD, Combo, or SuperDrive?)

Sep 25, 2012 7:58 PMby Ronda Wilson,So it is an iBook G3? (The iBook G4 models also have two USB ports.)
There are 13 different models of iBook G3 (Dual USB). Four of these have just a CD-ROM drive (no DVD capability and no CD-RW as standard). Three of them came with 128 MB of RAM soldered to the logic board.
Can you tell which model it is?
Do you know which version of the OS is installed?
Does the iBook start up? You can tell if the Caps Lock light comes on when you press the Caps Lock key.
If it starts up, can you shine a flashlight from behind the display and see anything on it?

Sep 25, 2012 8:51 PMby classiciBookuser19,It just has iBook on the inside cover and it has 128MB with the port soldered on the logic board. I'm not sure what OS it has on it, and it does start up, and the screen lit up today but the view was all scrambled. I didn't think to the flashlight technique. I'll try that when i get it back. The iBook was given to me.

This sounds like the infamous logic board problem:

This program is long-since over, as you can see, but the problem remains for older iBooks.
There is a shim fix which often works for these old iBooks. As suggested long ago by John Sawyer:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.
