    Can someone please help me find a guide on how to fix the tilt on my iMac G4 screen? It seems to have play in the joint closest to the screen itself which is terribly annoying.

    Thanks. :)

    Mine has a little bit of play in it too - and it was/is a common thing to occur with all iMacs of this design I believe.

    Your local Mac service centre have a special tool that tightens it apparently - I've never taken mine in - as it seemed too much hassle to lug it in to tighten a screw.

    Some ppl actually wedge a small piece of something at the top of the arm to level it - the travel in mine is only slight, so I haven't done that either - but I would love to purchase the tool that does this job - so I'd be interested to hear of anyone who has managed to secure one for their kit.

    Yes, I've had something wedged in mine since I got it but I'd really rather just fix it.

    Nobody makes the right allen key for that? I know it's a weird tri-prong thing but I'd have thought someone would be selling them.

    I can't seem to find anyone selling a tool that will work. Please let me know if you do. :)

    I just bought an iMac G4 for my GF and have the same losse arm-joint problem. How such problems make it all the way through production amazes me.

    That said... anyone know where to buy the three pronged tool to tighten it?

    There is no mention of this three-pronged tool in the Apple service manual.

    The only adjustment specified in the manual involves removing the LCD panel from the neck in order to adjust horizontal display tilt.

    A little bit of play in the neck is normal.

    I'm not complaining about play, I'm complaining that the display sits crooked.

    If the small amount of slop in the neck won't allow you to correct the crookedness, then disassembly of the display is required.

    The slop is the neck is enough to allow me to correct the crookedness with my hands, easily holding the display straight like it should be, but it will not sit straight on its' own for anything.

    I have the same problem on an iMac G4 800 20".

    It has been this way since Day 1, so it's a manufacturing "feature". I asked Apple about repair and they said to send it in, which I never did.

    I would love to hear about a solution even if it requires some disassembly.

    The only thing I've come up with, and I haven't gotten around to actually doing it yet, is to disassemble the screen and straighten it manually.

    In my case, it's not the screen itself that is crooked, rather the slack in the arm that holds the display, but I feel more comfortable taking this route instead of trying to tighten the arm somehow.

    I'll try to post pics when I get around to tackling this issue.

    I know this is an old thread and I'm new here but I was wondering if you fixed the problem? (The unevenness). I just got an iMac G4 from a friend, 20 inch great condition. The only problem is the screen is a little crooked and was hoping to fix this. Thanks.

    I did not. I actually ended up selling the machine to someone who didn't mind the issue. I believe there is a special tool made for tightening the hinge(s) on the arm. I would imagine that is what you need to fix the issue.

    Nope. Look closely at the hinges on the LCD arm in the following picture to get an idea of what kind of tool you would need.

    i know these screws but only with two holes and a bit bigger but for tighten them up you should simply be able to use some snapring pliers

    but the size of the pliers tips should nearly match the size of the holes otherwise you could slip and scratch the chrome
    cheaper then bringing the iMac to the next dealer sollution i would suggest to use the 90degree angle ones as they give more space to turn
