Controller signal weak at Phantom 3 SE
I have bay it as a repair object with Gimbal live is one life.
Change ribbon cable and a broken arm and now looks ok al engine run and green light from gimbal motherboard diode.
But then start to connect RC and drone only weak signal in field for WI-fi and controller signal.

No.
I should open it and take a look but it was drone that flight in a tree and damage gimbal for erlier owner RC looking new outside.
I recognize from another P3 that camera has not the mowe then power button On eventually ribbon cable or mother board have same problems and that block to connect good signal and take of.

Should I take away ribbon cable at mother board and test?

I have take away 2.4 GHz antenna and put new outside Antenna P3 std and that solve problem with weak signal but I think it better Antenna at P3se both in RC and Drone because of longer Range original.

From looking at the picture you posted, next to the red banner that says controller signal weak, the remote controller icon shows no connection at all between the remote controller and your tablet. When I have seen this before, it has been one of two things.
#1. A bad USB board in the remote controller.
#2. A bad USB cable.
If you used a cheap aftermarket ribbon cable to repair the camera, that could be an issue. Also, make sure the cable from the OFDM is not damaged or not connected properly.
