Hi,
Can the sounds of an active hard drive be heard at some point (indicating a normal startup)?
There is a problem with the graphics processing unit (GPU) and its ball grid array (BGA) on some iBook computers, leading to similar symptoms. Reflowing (resoldering) the BGA is a work for specialists, and is going to be expensive. A web search will return a number of more or less realistic alternative attempts to solve the issue. Outside pressure applied to the affected area has sometimes been used for troubleshooting, or even as a temporary "solution".
It is of course possible that the iBook in question has a completely different fault, such as a broken display cable.

With a correct vintage video display adapter and a VGA external display
you may be able to further diagnose the issue, be it a failed component
to the internal display or a main graphics processor. The adapter can
help troubleshoot the depth of this symptom, if you can locate one.
Good luck & happy computing! 🙂
