Hi,
Any ideas on what to do.

My Drone Crashed and i replace all the damage part but since then turning control on, plug the samsung tab, dji opens automatically, plug the battery on phantom, started it, controller shows green and wrote Ready to Go(GPR), gimbal moves, all nicely but no Single GPS.

But, No signal in on screen. there is clear image but nothing function i connected in dji assistant to my PC to update the firmware, after completion the same problem.


What could be an issue?

Thanks for ur advise

I'm not the expert you are looking for,but did you check all the antenna connections, even the ones in the legs? I'm talking in general terms. It seems to be a break down in transmission of the P4p. If not the antennas, then maybe the module before the antennas.   

Just a small point, but are you starting it up outside? you won't receive any GPS satellites inside.

Thanks for ur response, all seems connected ok, if i put off the P4P it reflected on the screen that Aircraft is disconnected. when i put on the P4P it will show Green and Ready to Go but nothing will work even it will not show battery percentage, no sign of sensor, no Frequency showing, no Altitude and distance counting all show zeros
