I recently had the biggest crash in 3 years of flying my Phantom 2 Vision Plus. The landing gear was ripped off. In addition to various cracks and scrapes, The compass cable had a break, and the camera took a big hit. I took the camera and gimbal apart and it seems to be working. I ordered a compass cable from Ebay and changed it. When I turned it on I get three bed blinking lights and a constant beep. Can someone please help.
