I've been moving my battlestation back into my Cave this weekend after it was vacated by a "visitor". Unfortunately in my rush I plugged my SEQv4 into a 7.5v supply which I use to power the majority of my kit. Every light came on with no display. After realising my error and going back to the proper 5v supply I have the same result. Every LED on the CS lights up, no display or response otherwise. Have I fried my Disco board?
