I'm trying to determine why my new Stargate machine is not working. The marquee lights up, but that's about it. Nothing on the monitor, no sound. I don't have any number showing up on the main board. I only have 2 LEDs lit, the bottom two. I will post a picture of the power supply. What's the next step? I suspect I need to rebuild the PS board, but how do I determine whether it might be the transformer output instead? Or perhaps the connections between the two. I have a multimeter, but I'm not sure exactly how to test it. I am a beginner.
