Q: Old Powerbook Ti (M8859LL/A) Display Wonkiness
Howdy all.
At a recent estate sale, I picked up a box labeled "random electronics" on the cheap and, to my surprise, I found an old PowerBook G4 Ti buried at the bottom of it. Other than being dusty from being packed away, it seemed in decent condition. After a bit of TLC, and a fresh install of retail Tiger, it runs great, but it has this strange bit of display wonkiness.
It's hard to describe, so I'll drop some images here at the bottom for viewing. I've dealt with image persistence on various LCD screens I've had to support and fix in the past, but this seems more nefarious than simple image persistence. Indeed, trying to "white out" the image has yielded no results. The effect is too static for me to suspect the GPU as it displays on screen just fine. I haven't tried hooking it up to an external display yet just to be sure, however.
I'd love to hear some opinions on what this may be. Even if it can't be fixed, it's still useable and it's a nice little machine to have while just lounging around the house.
Here's links to two images:
Image 1: While looking at it as if using it with medium backlight.
Image 2: Looking at it from an elevated position, on a slight angle.
Thanks in advance!
