I just broke the display of a friend ibook G4, i've found other ibook that doesn't work for the replacement but i don't know how. I was wondering if anybody have a link to a site that can show it to me with pictures.
Perhaps I'm being dumb, but I don't see instructions for swapping the LCDs there. Not listed in the contents anyway. Like Mord says, its not hard. Four hex screws in the side of the display to start with. Then use something thinnish made of plastic (metal will scratch) to pop the back off the display. The LCD and its aluminium shield are held in by screws which attach the LCD to the frame. Two on either side. You may find that the shield is also held by one or two long screws down near the hinge (I might be thinking of the G3s there). Anyway, remove the shield carefully, watch the tape as it can pull on the LVDS cable and damage it. Then you can disconnect the cable, disconnect the backlight cable from the inverter board (this runs along the bottom, below the LCD), and remove the LCD.
Things will only get fun if you are unlucky enough to get a slightly different panel with a different LVDS connector. Then you will need to swap the cable too. Might be easier to just swap the whole top half in that case.
