    Hello All, Hoping to get some help with the internal speaker not working. I was testing a logic board that I recently bought as an extra to have on hand.

    Feint moving lines on 5400 when adjusting brightness / contrast

    I just picked up a week ago a Power Mac 5400 AIO system. I’ve been playing around with it some, and it works perfectly except for one thing I’ve noticed. When adjusting brightness and contrast, very feint slow scrolling lines will appear. It only happens when adjusting the monitor controls, and...

    Scratched up AntiGlare screen on a Apple Studio Display?

    I picked up an Apple g4 studio display today. One of those where the entire back is clear and sits on a swirled acrylic stand. Got it home and plugged it into my Powermac g4 and works fine. However that's when I noticed that the front of the screen looks scratched, and becomes quite distracting...
