I have the DLP connected on a 5V 3Amps power supply and shows the default screen when it is not connected with the beaglebone black. In the beginning it worked fine with the beaglebone. Now, out of the blue, it doesn't show anything and the D3 led is blinking, whereas D2 is off. I can connect to the beaglebone but the DLP does not show anything. Any ideas?
