I am new to drone flying. Slow flyers, helicopters, jets and war planes. I bought the DJI Flamewheel F550 RTF Package w/DEVO 7 setup for NAZA V2. Has the SKY-708 7" monitor w/Diversity Receiver and Recorder. Everything works fine, except the monitor. Can't get a picture on the monitor, only snow. Does anyone know a repair shop in San Antonio that I can take it to. Any help would be greatly appreciated.
