Display Error on 5200CD
I just got an old performa 5200CD. The display worked fine, but now for some reason the display is off (smaller and hangs to the lower left). It's like i need to resize the physical screen like i do on my pc, but i cannot find the controls for it. Like the horizontal and vertical positions. Where are they located? Please help.

You can configure the picture tube position via two paperclip holes on the rear right side of the machine (near the top). They are marked with the 'position up/down' and 'position left/right' symbols. This can help with centering the screen.

Unfortunately, the 5200 models do not have AppleVision support, so you can't change the geometry of the picture tube display via software in the Monitors Control Panel. I believe there are controls to increase the size of the picture up/down and left/right on the inside of the case near the rear, but this is a big pain, because you have to take the entire case apart/off. To take the case apart you need an 18" Torx-12 screw driver (Mac cracker), and a gentle hand with plastic.

where can i buy a torx-12? Also, i push the paper clips into the back of the mac, but the screen just jumps to the left, or down. then i pull the paper clip out, and it goes right back to where it was. Any suggestions why? Or maybe i'm not doing it right.

I bought my 'Mac cracker' at Fry's Electronics, but I'm not sure who has them for sale online. Actually, after looking at my 5215CD, I realized that you don't need the 18" shaft to take apart the 5200 series cases. Don't know why I got that confused. A good hardware store (NOT Home Depot) should have Torx screw driver bits (it's a Torx-12 size on the 5200).

My mistake again with regard to the screen adjustment holes on the back. They're actually adjustable with a small screwdriver. Make sure not to break them off, since they're plastic and it becomes very hard to adjust the screen once they break.

There is also an obscure utility from Apple that can control such things as position and geometry. I don't think I have it here at school, but if you are interested, e-mail me and I will look for it.
