Ibook powers up but there is nothing on the screen. Before, it was intermittent like a loose connection but now there is nothing. I've taken the thing apart and have the LCD removed.There is no evidence of a bad connection. I'm trying to find a schematic to locate the power wire coming into the LCD just to see if this is the problem. Any suggestions? It is not the clamshell

Re: ibook powers up but no video
Before disassembling the unit, the recommended way to diagnose a display failure is to use the appropriate adapter to connect the iBook to an external display or TV. If the external display shows an image, the internal display assembly is at fault; otherwise, it could be the graphics processor or logic board. This step may be more difficult now that you have your unit apart.
Two cable sets drive the display. One provides image signal, the other provides power to the backlight. It is common for them to fray where they run through the hinges. Either or both could be the cause of your problem. Another possibility is that your backlight has burned out, as it is nothing but a small fluorescent tube and they fail with age.

The good news: since it's intermittent it's probably a simple loose or dirty electrical connection. In other words, nothing major. The bad news: intermittent problems are very difficult to find, because by Murphy's Law they won't show up when a mechanic's looking for them. Try unplugging and replugging every electrical plug you see under the hood. Sometimes that's enough to restore the connection. Also check your fuse box for a loose fuse, and (though this is unlikely) your battery cables. Good luck.
Hi, Check which video out connector your mac has (there have been a few in the last gew years) and then buy the appropriate adaptor from the apple store. (or ebay) This will give you a standard VGA connector that you can then connect to most monitors with a standard VGA lead.
Sounds like video card or video cable is faulty or loose. Is screen always blank no matter what you try? Were you getting intermittent screen flickering. There is a ribbon cable that runs from base to lid that sometimes get worn or loose from constant open/close of the lid. Try cranking lid to different positions while trying to boot up. You maybe able to find a video card under one of the covers on bottom. push card all the way inward to make sure it is seated correctly.
This is a problem with all iBook G3s. The CPU and graphics processor just aren't fast enough to process video well, especially online videos. In my iBook I have upgraded many of the components, but it still doesn't play videos well.
When watching videos you can try to close all other programs, turn off the wireless internet connection (if you have one), and reduce the screens resolution. Doing this will reduce the amount of information the computer has to process so that it can focus more on processing the video.
It is possible that the connection from the lcd to the video card is loose and making intermittent contact,i think this laptop does not have an integrated video chip so if the card is the problem you can replace it,you will have to dismantle the laptop in order to see if the connection is loose or not,another possiblty is that the cable to the screen is the problem,from the description you gave of the picture on your external monitor it is more than likely that the video card is causing you to have nothing on either screen,hope this helps let us know what happens
You fried your motherboard. It would have taken at least a week if not longer to get all the moisture out of your computer but since you started it while there was still water in it, it fried it. You will have to replace your motherboard.
Hi If you are still faced with this problem..... Possibly the video card has gone in the unit. The original screen on the laptop may have had an blown inverter which would not stop the funcioning of the external display. However for the external disply to stop working would suggest the video card. Before going this far have you checked to see if there is power to the external monitor? Have you tried the monitor on another computer? If the monitor works with another computer you can be certain there is more wrong with your poor old iBook. You will need to take it in to be looked at.
