    Brief Overview of Problem
    While I was in Sao Paulo in February, the display on my iBook went nuts: the top 1/3 is fine, if a little dim, but the bottom 2/3 is just vertical lines. So I went to an Apple repair shop here in Brazil and I was told I need the following part: LCD Panel 661-3097. However, since I am in Brazil, I don't really want to shell out a LOT of money to fix this, so I am attaching photos of my problem to see if you think my problem is something else, something CHEAPER! Or if it is the LCD, where can I get one cheap? I'm on a Brazilian's budget!

    Photos & Descriptions

    This photo shows that the display on my laptop is dimmer than the CRT monitor I'm now using. (NOTE: CRT Display is fine, just refreshing when I took picture)

    This shows the complete LCD screen on my iBook.

    This one shows a detail of the vertical lines on the bottom 2/3 of my screen

    QUESTIONS
    1. Do you think the LCD Display is really my problem, or could it be a relay or video cable or inverter?
    2. If it IS the LCD Display, where can I find a cheap one (less than $300)


    Thanks in advance for any help you can provide!

    System
    iBook G4 (14 in) 933 MHz; Mac OS X (10.3.9); 640 MB RAM, 60 GB Hard Drive

    plug in your CRT to your iBook if you get corruption on your CRT also its your ibook video card. If its only showing up on your LCD, its your iBook LCD. From the looks of it, it sounds like its the LCD. But what i mentioned above is the only way to make sure which it is.

    not really, you could try massaging the LCD screen gently to see if it makes a difference also you can try this: (BE VERY CAREFUL) try twisting your lcd screen to see if it makes it go away, i had a problem with an old dell awhile back where the LCD cable in the laptop itself was being pinched and causing artifacts. However if those tricks dont work your probably going to be needing a new LCD.



    edit: unless you fashion an LCD monitor to your ibook using the mini-vga port :p

    When did you buy it? You're not under warranty still?

    I was going to say, right off the bat, that it's a 'Logic' (mother) board problem. The G3 iBooks were notorious for having problems like this. I had one that needed to be replaced three times for similar issues.

    But if it displays on the CRT just fine, hrmm. Might be the cable, and not the LCD panel.

    If you're still under warranty, I would try sending it to Apple - hopefully they'd replace it for you, no charge.

    I had a problem like this on an old laptop. It turned out to be the cable that was coming loose from the inside of the laptop. So maybe try twisting and contorting it oh-so-gently.

    Thanks for the ideas guys!

    Massaging and contorting didn't work.... :( Oh, and I'm not under warranty, sadly.

    Also, sometimes the bottom 2/3 is completely black (I think after a while the colored lines creep in.)

    You guys have an idea how assured it is the LCD? If it's pretty certain, I'll have my parents buy an LCD right now and bring it down to Brazil to me. If it's still uncertain, I'll wait until I go back to the States in August and take it in to an authorized technician. Any help?? Thanks guys!

    I had the same problem with my iB G3, and it ended up being the Logic Board like crachoar said...

    Mine needed to be repaired after I dropped it, and was $500 to get it fixed --- :eek:

    Good Luck!
