Hello/ We have strange problem with A3 and Lightbridge 2. Everything was OKAY till now but today we could not connect to Light Bridge 2. A3's led blinks Yellow, and RC Status is FailSafe. We have upgraded and downgraded several times both A3 and Lightbridge 2 firmware but nothing has changed. And several times LED gave Solid RED (Critical error)  and  RED, GREEN, YELLOW Blinking Alternatively (diagnostic test). What are these problems? In the video I have explained problem. Please help us.
