iBook G4 Display Issue

[pammyspyce]

I bought my mom an iBook G4 on eBay a few months back. It's been working great until a few days ago. Her screen... I want to say it flickers but that's not right. It's like the display gets a little brighter for a second or two and then goes back to normal. I know this isn't good. I don't have any of the orignial software. Is there a way to run a hardware test still? I'm hoping it's not a huge problem (like the logicboard is failing). Any idea what it could be and how I could fix it?

Thanks!

Is this "flickering" at all related to moving the display? If it is, then it could be a loose or damaged hinge cable, which will weaken from opening and closing the screen a lot.

Yeah, it is related to movement. It flickers while on my lap but it did not flicker while sitting on the desk. I didn't even make that connection.
