The screen, the cable that connects to the screen or something internal has taken a hit. You'll need to get it serviced to find out which. Sorry, but there's not much diagnosis we can do from a distance.
Make sure that the power supply is good. If you have a good power supply, test with bootable Mac OS X install Disc.
Start the computer holding down the option button.
two icons should show up the disc icon and the hard drive icon.
select the install disc.
If everything boots OK then there is a problem with the hard drive.
If you can't boot at all there is other hardware problem(s).
You will then have to take it to a Apple Genius. Make sure you make an appointment first.
Got the same problem with my ibook G4. I have research on how to fix it, and found out that most model of G4 has the same problem. I soon found out the main problem and the solution, it would require some skill in soldering and dis assembling the whole laptop. Go to this site and hope it will help you just it like it helps me a lot!
The blue screen marks the start of the login process. If the Mac freezes there, it usually indicates that some third-party System Preference is hanging the boot process. There are several ways to diagnose the problem. The simplest is to hold down the Shift key after hearing the boot chime. This will disable third-party System Preferences and should allow you to come up to the login screen. Then you can review the third-party preferences and go to the website of each of them to make sure you have the most up-to-date version that is compatible with your level of the Mac OS.
The fact that the "BONG" sound (or better known as the MAC CHIME) does come on and nothing further means that the computer cannot find your hard drive or (sometimes worse) cannot find the operating system. This means that you will have to remove the hard drive... then insert it nice and firmly again. Try now to boot. If nothing happens then your drive has gone faulty and it could mean that you may have lost your data... NOT NECESSARILY though.... What I mean by that is that you may still be able to access the dat when you connect the "faulty" drive to another computer via USB with an external casing and then get your DATA off it.
That means Hardware Error. It is a gray iron curtain with a black dialog box. Most likely bad Ram/Memory, but If warranty, call Apple. Otherwise there should be a diagnostics CD or DVD that came with your recovery Disks. It should tell you what's wrong if it can boot before the Iron Curtain comes down again.
You can try swapping ram with a recent age mac or pc laptop and see if it repeats.
