The problem used to be the order you turn everything on. First the RC, Second the battery, Third the WiFi extender - and be sure the darn thing is fully charged!
In late 2016, DJI put in a firmware upgrade for the P2V, which, for all of us who upgraded thereafter, we could connect OK but got the dreaded "black screen." DJI finally realized the problem and that they had to fix it. By submitting the proper documentation showing that you owned the P2V before the upgrade, DJI said it would fix the problem for free. I did that, DJI accepted my documentation and sent me a shipping label, then received the message only a few days after I sent it that DJI had fixed the problem, but it would cost me $138. It seemed that they fixed some things* in addition to the black screen problem. I grumbled, but went ahead and paid the $138, because my P2V lacks the geofencing that prevents my P3P from flying near an airport,and I need to fly near a Class C airport with, of course, notification to the airport's ATC.
The upshot is that my P2V now flies as good as new for all that DJI did to it.
* One of the things I was charged for was a new upper shell. I was puzzled about that, because that would seem to have nothing to do with a black screen, and because as far as I knew, the shell was perfectly fine. Oh, and one other thing: From the day I first obtained my P2V four years ago or so, something rattled loosely inside it. The rattle didn't seem to affect flight at all, but nothing rattles in the repaired P2V now. Maybe fixing that rattle cost me additional $$$. DJI, understandably, couldn't return the P2V fixing just one problem and leaving me with others.
can connect to drone and such just get no information from it
