Just wondering what that could mean- It is on my PowerBook 150- It shows up sometimes and disappears and reappears while using the laptop....

Anyone have any idea?

Thanks

delamination of the screen cable to the screen or bad caps. Many threads on this. I think someone even posted a repair they made with the list of capacitors.

Is there any chance it could be to do with a slightly dodgy power adaptor?

Nah, I doubt it. One of my 160s had this issue and it wound up being bad caps.

Dam.....

Oh well looks like eventually it will need cap replacement :/

COF IC is bad, replace panel.

What is a COF IC, and where can I get a replacement?

COF = chip on film. Not entirely sure about that old of a panel, but the newer stuff the chip is epoxied/part of the film ribbon going to the panel and there is no replacement.
