Any chance it’s not a dead GPU?

Oh no! Can you get into the boot options etc, pre MorphOS booting? I have a G5 Tower, and will assume these are the same for a PowerBook:

- Hold down Option during boot chime to get to the boot selector or
- Command + Option + O + F to get top Open firmware

If either of these appear it's more likely to be software related.

If it's the graphic chip having an issue it won't display anything no matter what. You should have a DVI port on the side where you can connect an external monitor. That can help you test if it's the graphic chip or the LCD itself.

If it's the chip, it can still be repaired but it's a tedious work. It will require to take the whole logic board out and reflow the chip.

Ended up leaving a hairdryer blowing hot air inside it.
The only change was a melted function key

That’s really sad…
