Try restarting, if still not picture, then try hitting function key + F5 at the same time. Some laptops have a little icon the key that looks like a monitor as well.

If not try hooking up your laptop to a regular computer monitor and see if you can get a picture and fix the problem that way.

SOURCE: My powerbook G4 laptop screen will not come on it

You can open the computer up and see if the ribbon cable is connected firmly. Most likely the back light went out.

SOURCE: Powerbook won't start up

If you have the original install CD or the OSX CD, boot to CD. To do that you must insert CD, restart PowerBook and hold letter "C" on keyboard while computer is starting, then take the first steps towards installing the OS, when you get to the bar on the top go to Tool>Utilities>Disk Utilities then select the drive a do a disk repair. That may fix the problem and bring your system back to booting normally.

SOURCE: powerbook g4 going to white screen only!!

Do you have any external harddrive attached to it? If so, remove it before restarting. Try to start it up in safe mode by holding the Shift button down at startup: http://support.apple.com/kb/HT1455

Reset button on a powerbook g4


The Powerbook G4 power button functions like a reset button if you hold the power button in for a few seconds until the computer powers down.
  1. Hold the power button in for a few seconds (until you see the screen turn off/go black and hear the fans & hard drive stop spinning).
  2. Press the power button again to turn your computer on.
  3. If you have more trouble, you may need to boot in Safe Mode or "perform a Safe Boot":
    Press and hold down the "Shift" key immediately after you hear the start-up tone. Release the "Shift" key when the gray Apple icon appears on the screen.

When I power up my PowerBook G4, I hear the startup chime but the screen stays black, nothing happens!! Is my screen turned off or something?


It seems likely that the PMU (Power Management Unit) has failed and needs to be reset. There are comprehensive instructions on how to do this at the apple support site. Apple Support: PMU reset

Hi, I have a PowerBook G4 17" laptop and the monitor has gone dim, to where it appears black. I can barely see images on the screen, but the backlight is not working. Could this be a video inverter...


Yes, this does sound like it's an inverter issue.
The only way to get this part is straight from Apple or from a Authorized Service Provider who get there parts straight from Apple.

My screen flickers and goes out sporadically.


Bad video graphics chip on logic board. Probably made by Nvidia. Repair logic board or replace the logic board.

An area on the display it's not working. PowerBook G4


I'm sorry to say that you will have to replace the screen soon. That vertical black and white lines that appear is the early warning signs that your screen will soon go blurry, or have a partial screen, or have it just stop working. This happens from the many times the screen was lifted open and closed and the ribbon cables just need to be replaced. And since the ribbon cables can't be simply unplugged and then replaced, you will just need to get a new replacement screen.
