Hi and welcome,
This is odd as code 2002= badPublicMovieAtom, which is quicktime related as far as I know.
A flashing question mark when you start your Mac, means it can't find the system software it needs to start up.
Try starting in safe mode and running disk verify and repiar. If you are unable to get into safe mode then try the following.
Have you got the original install disks that came with the Mac?
Make sure the Mac is off and insert your Mac OS X installation disc. Be sure to use the disk that came with your Mac.
- Restart the computer, then hold the C key during startup.
- From the Utilities menu, choose Disk Utility. Don't click Continue.
- Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
- Click the First Aid tab.
- Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
- After repairing the disk, try to start up normally.
