Hey, I received an iBook G4 1.2 from a friend who had screen issues with it. After tooling around with it the screen started working again. As i was reinstalling tiger The screen went dim then completely black. I searched the interent for potential problems and came across the cracking on the video chip solders. I took the back off and pressed on the chip to see if the screen would turn on but nothing, I press with quite a bit of force too, So i'm assuming the chips is fine. I also came across a bad inverter will cause the screen to dim but would a bad inverter cause the screen to go completely black? If anyone has any advise please let me know. I appreciate any responses. Thanks.
