So I just got my hands on a Crystal Castles board for a Cabinet that I am restoring and am trying to work out the kinks with the board. So where it stands right now I am getting random garbage on screen. I am running it on a switcher for testing and am getting clean voltage across the board. Some of the things I already replaced were the 2 filter caps near the edge connectors and the 10MHz crystal. When I got the board the first thing my eyes darted to was the crystal because you could visibly see it rattling and pushing it with your finger you could hear stuff inside it shaking around so i replaced that before ever even powering the board. Now, I am pretty new to using an oscilloscope and I don't have the best one or anything but it's worked in the past so I am trusting its readings. So anyways, when I connect the scope probe all up and test the TP labeled 10MHz I notice that I am only getting around 13khz. So I was just wondering if anyone else has had the same problem or could give me a place to look. I'm not to familiar with clock circuits so hoping to learn a few helpful skills from this repair!
