I'm not exactly sure what you are asking now. All the white/clear iBook G3s and all G4s have identical display data (LVDS) connectors on their logic boards.
The LCDs vary however, sometimes the same model of iBook can have more than one make and model of LCD panel. Some of these have the same connecters on the LCD end, but some are different. I don't think I have seen more than two or three variants though. Bottom line is, if you have a cable that connects to the LCD, it will connect to and work with any iBook logic board later than a clamshell.
If you lift the whole top half from one iBook and connect it to another, it will be fine (though there is more variation with the connectors and lengths of inverter and antenna cables, and only some have reed switches in the lid).

I'm rambling now, but basically, if the cable fits in the back of the LCD, you are good to go.

It does fit, because i ordered the G4 LCD cable first, the narrow connector. I originally had a wide connector which is why i couldn't plug it to my G3 screen. I also ordered a G3 LCD cable just in case the G4 one doesn't work. So since it fits the LCD panel connector, you think it should work?

It should. The only other variant is the length. The 12" cables are too short for 14"ers.

Ok i tried plugging the new G4 LVDS cable, everything fits on both, the motherboard and on the G3 screen as well. The problem is, the monitor won't turn on. I also tried external monitor and they won't get a signal either. What do you think is wrong here? My DVI worked fine before, but since i took out the old broken screen out, i haven't had a successfull output since.

Well to be sure, disconnect the LCD and try the external again. If it works, then you have fried the LCD after all. If you still get no video, squeeze the GPU while you reboot. If it comes back on your board has failed with the classic iBook problem.

None of the above work. The computer does turn on and my monitor turns on just as soon as the computer is powered on when connected via VGA, but doesn't go further than that in it's signal.

Nevermind, i fixed it at last! I was pressing on the wrong chip when trying if it was the GPU. I kept pressing the top part of the heat sink, but the chip in in the lower part. That brought the screen to life! ;D

I've 2 G4 iBooks in my possession as of today. One logic board died, the other LCD died. I can't swap the LCDs because theres a 2 wire difference on the LCD power harness. Is there anything I can do about this? -I posted in another thread, but later found this one matches the subject. Thank you
