I thing you are very lucky that your iBook G4 has lasted this long.
This model was /is notorious for having bad solder joints on the graphics chip which would cause the display to throw all sorts of video images, everything except a picture, and would also cause the machine to not boot.
Been struggling for months about how to fix this issue. I own an iBook
G4 (OS X 10.4.1 Tiger) as of 2005 or so that has worked perfectly
since. I also own this MacBook which I am using to write this plea for
assistance, but use the iBook as a computer for all of my quirky gaming
crap. Anyways, it's still a very important device to me. Back to the
I have dropped my iBook G4 off of my bed a couple of times as it slides
off of my lap, but has worked 100% fine after, except for immediatley
following the most recent drop. The first time I dropped it, it fell
about 1 foot onto my hardwood floor. It landed on its side as the
notebook moniter was at a 90 degree angle. This caused a crack in the
upper-right hand corner in the [only] the plastic and the iBook still
worked fine. I dropped it a second time while playing a fullscreen game
in the same scenario off of my bed, and the screen turned blank white.
Let me set this straight: It appears that MOST all of the computer is
working fine (still hear startup noises, battery works, powers up, etc.)
But here's where it goes wrong:
I start up the iBook G4, hear that famous Apple chime, the screen
backlight comes on, and I am left with nothing but a blank whitish
grayish screen! No Apple logo or anything that I can see. No sunburst
loading circle. Nothing but a blank white screen. The volume can still
be adjusted (makes the squishing noises) but the brightness cannot. I am
assuming that something got unconfortably jumbled or disconnected in
the iBook during that last fall. I have heard that it may have something
to do with a LVDS connector cable or something. The backlight DOES
still work, there is just no icons, words, etc. on the screen; just
blank white light.
Due to my cat-like curiosity and strong desire to get this thing fixed, I
attempted part dissassembly without know exactly what I was looking to
fix. I got overwhelemed and will soon be re-assembling the device until
someone can confidently tell me what I need to get in there and do! I
I have suspicion that it is the LVDS cable needing a bump or nudge into a
socket of some sort, but I have no proof to base this on other than
reading about semi-similar problems on the Internet.
However, in related problems, usually their screen is black. Mine is
white. I am not in a financial place to be spending any $$$ on a new
cable, part, etc. but I do believe that this problem is self-fixable for
Issue Overview after drop:
-Notebook powers up + chimes
-Screen light comes on, but stays at a blank white screen
-Sound volume works, brightness does not
