Hi, I recently picked up a cheap 20" G5 (a1076) for a project. When I power it on, it will make the chime sound and I can hear fans but absolutely no image is on the screen. I don't even see the screen light up at all (not sure if the back light is supposed to come on during startup). I ordered a capacitor kit for the logic board but since I don't get any image at all I'm doubting that's the issue. Any advice would be appreciated, I'm going to try and connect it to another monitor to see if I get any image there, do I just need that mini-DVI to hdmi cable or is there other things I need to connect it to a different monitor?
