Powerbook G4 1.33 12" screen...broken?

Is the GPU the GeForce4 420 Go? This is a bit of shot in the dark, but back when I had my 12" over time I began to get artefacts on screen that are very similar to what you're getting, when doing something even 'relatively' intense (iTunes visualiser, Top Sites etc.), this got worse as time went on & I ended up coming to the conclusion that it's the GPU. It seemed I wasn't alone either as a few other people posted similar experiences with that card.
Dude,
I think your video chip might be shot.. But the best way to test to see if its just the screen and not the chip. Hook up your machine to a monitor. If its NOT exhibiting the same behavior, then the video is fine.. and just your screen is broken.. If not, then the video is bad and this means a whole new logic board is needed
You can't just unsolder the video chip and put a new on in there, though I suppose you can. Best bet is to find either a new machine or get the logic board for it.
Here are some places to start:
www.dvwarehouse.com
www.applecomponents.com
Both are cool and I use them all the time when I need parts.

Yes it seems like a graphics card issue. Sometimes the chip itself is bad and need to be replaced (likely to be pricey) and sometimes it is "just" the solder connection which is bad and it can either be resoldered (cheaper) or reballed (more expensive). Getting a new board is also an option.
Is that supposed to be OS X installation screen?

Not worth it, a replacement Logic board on Ebay is cheaper, that is, if you find one.
Or, even a whole "new" 12' G4.
