Question about Apple 15" PowerBook G4 Aluminum 1.67 GHz LCD Display (p/n 1002587) (661-3749 1002587) Mac Notebook
Have a powerbook G4 15" whose screen looks to be inverted. I have a backlight keyboard. A 3year old got a hold of a key and pulled it off, I promptly replace it back on to the keyboard. Any insight into getting the display back to the aqua blue. Thanks.
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."

This solution is for Mac OS X go to system preferences then to the control panel Universal Access under seeing tab there is a DISPLAY Area it is probably showing up white on black change it to black on white.
Hope this helps.

A flickering screen may be caused by the computer detecting incorrect display settings as it starts or returns from sleep.
It can also come from changes to the screen resolution settings caused by a new program or update installation.
Verify screen resolution before assuming the issue is hardware related.
Next to the display screen behind the plastic screen bezel is a small component called the inverter, which supplies power to the screen backlight.
The flickering indicates the power is not reaching the backlight.
To fix the issue, replace the inverter.
The wires and cables traveling from the display around the hinges and into the motherboard tend to wear at the hinge area.
Over time, the opening and closing of the screen causes this wear.
The solution is to disassemble the plastic casing of the laptop, reorganize the cables so they have no interference from hinges, or replace the cables and connectors with new ones made specifically for the computer make and model experiencing the issue.
hope this helps
