P4P+ No Downlink

[CG Drone]

P4P+
Crashed Last fall, sent it off for repair to USAS. Bent Landing Gear, and No Downlink Signal. They changed the Landing Gear. With shipping and an extra flat ribbon wire, $360 Later, it worked fine when I got it back.
No more crashes, and flies just fine, but now all of a sudden, it doesn't have the downlink. No video image or battery info, says 'No SD Card', Gimbal doesn't move with the knob (but the gimbal works when holding the drone and move it around).
I don't want to send it off for another big repair bill, when it's probably a minor repair I could do myself.

Any Ideas ?
Thanks,
Chuck

I have the Plus, but have not had your problem. I did lose maps once, and that required a "factory reset" of the Plus controller. After that, all was back to normal.
I'd try a reset before I sent it back.

I would also try a different SD card as a starting point.
