Hello. I crashed my phantom 4 and had to replace the shell housing (top and bottom). As I was putting it back together (oh yea I did the repair myself), I hooked up the wires to the motors and I put a battery in and the lights lit up like normal. Red and flashing green. But I hooked up the senor wires and turned it on and all the lights were solid red. I checked all the wires to make sure they were conected. Can any one tell me how to fix this problem?

What does the Sensors section of the app settings show for the compass?
