I received a Diamond Audio board, D5 1200.1 board. It was missing some surface mount transistors, and might be missing some other parts, I am not sure. I have compared pics of my board to other working boards and it looks the same. When the fuses are removed, there is 13.8 volts throughout the board, but when the fuses are reinserted, the voltage drops to 0.55 or so and there is a buzz from the baord. The protect lights do not come on either. I need a good pic of the board, or some help on where to start troubleshooting. Heard of this before???
