Hi I recently got a A1025 Powerbook G4 and the right speaker is not working. I tried resetting the PRAM and NVRAM and neither worked. The right speaker works when I plug in headphones. Here is a picture of the logic board, I do not know what I have to take out to get to the right speaker or if I have to go through the top. I just do not want to take out more than I have to.
