update: i tried to manually apply pressure (like shimming) to the chip while turning on the machine, but it had no effect: nothing on the screen, but the computer was booting nicel…

Some people say the iBook G4 has the "video chip coming loose from the PC board" issue. There is also a pin that comes unsoldered on a voltage regulator chip. The latter is fixable…
