Hello! I am new here but I am undertaking a DIY Project with my old PowerBook G4 17in. I pretty much dismantled the display from the body. It was all looking good until I went to mount it under my cabinet. I was holding the two seperate pieces ( I know, but I was in a hurry!) and I kept moving them around. Eventually the screen flickered and then went dark. I know the screen is still getting the video feed, and I can remote desktop into it. If I hold a light up to the screen I can see the desktop. Should I look at the inverter board, cables, logic board, or bulb? Thanks!
