But we got one problem. We made a button to start the power behind the cabinet, but Raspberry Pi doesn't start, it seems that is turned on because the LED of Raspberry pi start with Red and Green color, but the monitor doesn't recognizes it, and nothing happen. To Resolve it i have to connect and reconnect the power cord of Raspberry Pi everytime i power the cabinet, Any solution?
Perhaps it comes from the SD card. Did you try to remake it. Are all the partitions visible with linux. I often had this problem. The sd connector of the raspberry pi is not very good.
