problem with my ibook G4 display

Hi,

This is my first post on this forum and I need help.
It appears 2 days ago.
I'm on 10.3.9
G4 1.2
Trouble : stranges pixels (green/ yellow/ bleu) appear on my display especially when I'm using Safari or Firefox. It's look like a "checkerboard" (Damier in French) made in an horizontal line.
I've try to : clean my ram but it still to be there after a restart.
It doesn't seem to be an hardware problem as when I use Capture this manifestations still visible at the same place on the pict.
It can be modify (Clean) when i change colours (million to thousand)as it deseapper. When i move an icone on the strange part of the screen it act as a gum.

As i want to use my computer with millions colors I need help to find a way to solve this problem.
Thanks in advance for your time and your help and excuse me for my bad english
