Question about Apple 15" PowerBook G4 Aluminum 1.67 GHz LCD Display (p/n 1002587) (661-3749 1002587) Mac Notebook
Cut the airport off and back on again. After that, delete any wifi profiles you have, and then re-add them. This will clear any corrupt profiles and troubleshoot that. If you can't connect to anything after that, check that the airport card is connected securely. If, after all that, it still isn't working, and other devices are able to connect to the same network, then your airport card is probably no longer working.

SOURCE: lcd is not working
This could be a backlight issue, an inverter issue or a logic board issue. Given that you dropped it, the backlight issue is the most likely because the ccfl bulbs inside the screen are breakable. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, it's a pretty arduous repair that requires 1-2 hours for a trained person. It's feasible to do it yourself if you're tech savy, but you'll most likely have to google for guides that show you exactly how to replace the backlight step by step. Check on ifixit on how to take the screen apart and make sure inverter is still connected properly. If so, you have a backlight issue. I work for Mac Repair NYC and i have to fix this problem a lot, it's so easy to break the lightbulb in the process.

It sounds like the system is corrupted. What I would do is to get your instal disk and boot up holding down the c key on your keyboard. Once you have booted up go to the file menu and run disk utility to verify and repair the hard drive if necessary. Then go to the instal menu and instal a fresh system remembering to preserve the users data so you do not wipe anything. Hopefully this will work.

First, make a magic pass of your hands, like David Copperfield. Then press these four keys: control-option-command-8. Presto!
If no presto (oddly, there's no presto on my system, and I know it's not for lack of mana), visit System Preferences / Universal Access and click the button that says "black on white."
