Tried to search but couldn't come up with anything useful. I just got an iMac g4 off CL for 80 bucks and the inverter board needs to be replaced. I found that you can take the lcd off by removing the three screws at the bottom to replace the board. But, I can't seem the find the right size bit for my screw driver to fit into the screw holes. Anyone know what size they are? Or the best tool they have found to unscrew them? Thanks all.
