I was adjusting the cables on the lcd while my powerbook was on (Stupid i know, but i was half asleep), and my hand hit the power button on accident and my screwdriver arced the power cable for the lcd. Now there is no sound.

I was wondering if all of the sound components are contained on the power/sound board, and if I could just replace it and regain sound.

Thank you,
Steven Jenkins

PS: I am using it right now so at least the power components aren't fried.
