Re: ibook g4 - screen will not appear
Try adjusting the monitor brightness (F2). If you have an extra monitor, try connecting the mini VGA to see if it outputs a signal extenally. The videocard is onboard the logicboard....so, that is one way to process of eliminate.
Also, if you start the machine after the apple chime, hold down the OPTION key. This will prompt you as to which bootable volume to boot from. What this does though, is gives the monitor a signal before the operating system loads.....this usually eliminates the issue being software, but very seldom is no display a software issue.....

Option 1: If you restart the computer and just after it restarts if you hold down
the eject key on the keyboard it should eject the disc, if not I would
check to see if there is a tiny hole on the disc drive that you can
stick a paper clip in - not sure if the ibook will have it but worth
1. Restart the computer.
2. Immediately after the startup sound, press and hold the key
Note: The Command key has the Apple icon on it.
3. Release the keys when you see a white screen that says "Welcome to
4. At the prompt, type: eject cd
5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the
action is complete.
6. Type: mac-boot

You might want to look on eBay for a replacement keyboard. I'm not sure how difficult it would be to unplug the old keyboard and plug in the new. Opening the iBooks is a challenge, but maybe the keyboard can be plugged in through the hole in the top. Not sure.
That screen will most likely be compatible - I work on these for a living. The G3 laptop screens are usually not compatible with the G4 laptops, but all G4 laptop screens are compatible with eachother (provided they are the same size, of course.
The face is probably frowning. The computer cannot find the operating system. Use a utility disk to boot up the computer and then use First Aid or Disk Utility to check the disk. You may have to re-install the operating system. This can be done without losing your files if done correctly. Seek help from an Apple repair facility if you are in doubt about how to do it.
I think the first thing you should do is make all updates. I know that in some versions of the iBook G4, the trackpad does not work after installing OS X 10.4 (Tiger) before you do the updates. Update your OS X first. secondly, does the button work? Does the trackpad show up in the System Preferences menu? (under keyboard and mouse). It's very unlikely that the trackpad came unhooked unless someone has opened up your computer. If they have, there is a really good chance that they didn't plug it back in, because it's a hassle and easy to forget.
Locate the following
keys on the keyboard: Command, Option, P, and R. You will need to hold
these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values.
The clock settings may be reset to a default date on some models.
Resetting PMU on PowerBook or iBook computers
In some troubleshooting situations, if resetting PRAM does not
resolve an issue, resetting the PMU may be the next appropriate step.
For information on when this is appropriate and for instructions on how
to reset the PMU in your PowerBook computer, see Resetting PowerBook and iBook Power Management Unit (PMU).
Try resetting the PRAM by turning on the iBook then holding option + command + P + R and wait till u hear another chime. If it still freezes, it may indicate an application may be causing it to lock up hold shift after you hear the chime to boot OS X into safe boot.
