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.

Try using it with an external monitor with a Mini-VGA > VGA adapter. If you get video than the you don't have a graphics card issue. If it is just the inverter, you will still be able to see a very dim/faint image, there just won't be any backlight.
