I got a Cobra main board and a 7" LCD display yesterday. I managed to run theLED on/off program on the Cobra board. When I connect the LCD display to the cobra borad using the cable provides (of couse, power disconnected), it has stoped working the cobra board. When I disconnected LCD display, it worked again.
I used the 6V 2 A power supply, cobra board works fine without the LCD display. Can you help me please?
