Hi guys, I am fairly new to the Mavic air, having only used cheap drones in the past, I am getting all red lights after powering on and no connection to my phone, I bought this 2nd hand and it worked fine for the 1st week, It has not been crashed and only flown over some fields as I wanted to get used to it. should i send for repair or can anyone advise a newbie. 
Thanks in advance
