    This is copied verbatim from my thread on Macfora, because I'm a lazy bastard:

    So today, I came home from school, and started to play some Medal of Honor on my PB*. Since I upgraded to 10.3.8 a day or two ago, I would get some weird graphics problem after a little while. The screen would be covered in weird little blocks, and I could see the outlines of the surfaces on the map. Quitting, putting the PB to sleep, then waking it up would clear it, and I was set to go on my merry way. Today though, I decided to play some Battlefield 1942 after, because I was still ready to shoot some polygons. As soon as I went to pick which battle I wanted, the graphics went wacky again, only this time, it did't go away.

    So now it looks like this.

    for the past few weeks, I noticed that whenever I walked into my room with my shoes on, and either touched my PB or put my iPod in the dock, I would get a static pop. I fear that this may have caused the problem, what with the Firewire port being in close proximity to the video chips on the logic board.

    Here's what I've tried to remedy the problem:
    Booted from external backup
    Reset PRAM (twice)
    Reset PMU (twice)
    Shut down and let it sit.

    Once I track down my hardware test DVD and my Panther CDs, I'll run the test and archive-install to see if I can nail it to hardware or software.


    I really hope I don't have to replace hte logic board, I don't have enough money for it :(


    * 1.25GHz 15", 768MB RAM (256MB from Apple, 512MB self installed, no problems with it since July).

    if it turns out it was the static, it time to get a humidifer in your room.

    If the unit is still under warranty, have it repaired now. It looks like the logic board as you suspected. If it's out of warranty, check around for prices. Apple should charge about $300 USD.

    It looks as though the wires connecting the inverter/screen to the Logic Board are loose. Open it up and try to reseat the connection. I had a similar problem after a minor fall.

    Otherwise, take it to an Apple Store or a Reseller, maybe some software problem, or hardware they can fix.

    ...and void your warrenty while your at it...

    Call up Apple now and tell 'em that its doing funky stuff after 10.3.8.

    You do have AppleCare, right? Its nearly essential to have with a PowerBook/iBook unless you have a place like Best Buy do your warranty. But AppleCare will be able to fix you up (in theory).

    :) Are you from Arizona or something? As a former "Rhodylanduh" now living in "Nawf Kalinuh", when I visit Lil Rhody and people complain about the humidity, all I can do is laugh. Loudly. In their face.

    My suggestion, put something (largish? grounded?) metal in your room (at your desk) to touch and discharge static electricity on before fondling your PB.

    I don't think it's the connection, as I doubt that would show up in a screenshot.
    It is not under warranty. I didn't have the $$ for the extra 2 years when I bought it, nor any time within the first year (they even called me :()
    I looked at logic board prices, and pbparts.com shows $1299 for my model ($300?! I wish!
    Also, I showed the shot to my brother (B.S. in Computer Engineering and he says part or all of the Video RAM is fried. TechTool Pro 4 agrees. :(

    Before you dismiss the cost that Apple would charge, I would suggest that you drop by the nearest Apple store, or if one isn't close, care AppleCare and request a quote....

    And give them $50 that I don't have? HA! I'll just go to the store in Cambridge while I'm on break next week. I also emailed PowerBookResQ to see what they say.

    At least you are honest about it.

    Now this is a strange twist. I went to the BMAC meeting last week, with every intention of handing off my PB to the guys at Tech Superpowers. After the meeting was over, I opened up my PB, and BAM, the pattern went away. A reboot (due to a Kernal Panic :() later, it's still going. If you look closely, you can see "grain" on any brushed metal areas (such as Safari), and transparent parts (Terminal, MenuTunes) show an odd pattern. The weirdest part is, TechToolPro says the Video RAM passes the test :confused:

    Well, I guess I'll wait until after Macworld to get it fixed. Ian from TSp told me it was a depot repair. They just send it to Apple, and $400 later, it's fixed.
