Poor man. I bought a phantom 2 vision plus when they first come out. Bad move. My wifi is not working on the drone. Black screen on phone, and wifi will not connect to drone. Says no internet connection.problem Is the little wifi receiver box on the drone itself on top.See if you’re drone gets hot in that area while just sitting on the bench left on. You prob try……. look underneath the drone near the landing gear and you may find a button that puts the drone in receiving mode so it can communicate with a new controller. I will put a link that I watched. https://youtu.be/dfY_VElgEXg Hope it helps.
Wife has same one and same problem. Took to the shop to get fixed but the battery for it would have to be ordered in. Was a totally dead battery. $120. Or there about. Really not worth fixing because you can now buy better ones for close to price new.
