Hi I've been running a gecko g540 for almost two years now and just last weekend I couldn't get a red light on it much less green. After a bit of probing around I found the the circuit board ground and my ground wires have no continuity. The green pin tray plastic has a small amount of brown colouration around the ground pin. Has anyone else had this problem? Something obviously burned out between the terminal and the circuit board. Any ideas what the cause would be? I have a surge protector on the setup so I doubt it would be surges. Obviously there was a lot of current in there at some point. Also any ideas on how I could fix the screw terminal so I don't have to solder a wire directly to the gecko?
