    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!
