Solid grey screen after replacing LCD
This is partially addressed in a different post. That post was under a different subject so I decided to start a new thread.
I have an iBook G4 which only shows a grey screen when turned on. It sounds like it's booting up and I can even put it to sleep with command-option-eject.
It was working fine until I replaced the LCD due to minor issues with the original LCD. I have replaced the original LCD-same problem.
I have reseated the display cable on the LCD and on the motherboard.
NOTE: I don't have a VGA adapter to test with an external monitor. I will be ordering one if necessary.
Any suggestions what the problem could be?
You need to test the ibook with an external monitor to find out if the LVDS (video) cable or the logic board is the culprit. If you don't have the mini VGA to VGA adapter and you're located near an Apple store, bring the iBook in and ask a genius to connect it to a monitor. To check if the problem is software related just boot the ibook with an external source like the installation disk or a OSX firewire external drive or from another compatible Mac using the firewire target mode.
I have the same problem on a g4 2004 model APPLE .I am going to reinstall the lcd and have already reinstalled the logic board.(which has tested fine .A new osx was installed and ibook is talking all the way thru set up.Is it the lvds cable or another problem with the lcd screen?
Although this is a quiete old post, it seem sthat the problem remains challenging...
I have the same problem with my sisters's iBook G4 (14 inch, 2005 model). Grey screen after start, extrnal video works fine. I also changed the display, no effect.
Does anybody got a solution in the meantime?
