I have a ibook that powers up but has no display, is it an easy fix? how much will it cost?

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! 🙂
