A few days ago my Echolab Opera just stopped. The switcher has power and displays the SN, the status light on the back where the memory card goes is light up green, inside on the HD it is lite up green. On the back are the letters A B C D. A and D are orange, the others are blank. Any ideas about this? I know Blackmagic bought them out and don't offer support anymore, but I am hoping someone can tell me better than buy a new switcher. Please respond with any help.
