then try applying pressure, squeezing, to the left of the trackpad but on the same level
You may be surprised at the results.
The iBook G4 was notorious for this problem which is caused by broken solder joints on the graphics chip connections to the logicboard.
just got this iBook 12" in the mail been to a mac shop before i bought it where the owner was told the screen had died.
Motherboard was said to be Ok by the repairer
I replaced the screen with a know working one and the screen was dead.
Then after the fiddle of pulling it apart again wondered if i could use the hard drive on another ibook.
The hard drive i put in another iBook which loaded up fine with display.
later i tried again but it was a dead screen?
*Is it that both ibooks have faulty motherboards?
Motherboard determines a display?
Or could it be the display module ?
What else could cause dead screen?
