I am getting this error on my ipad.
Camera Sensor Error
Hardware Malfunction Contact DJI Support for repairs.

No video is displayed on my ipad. It also flashes red at the top saying No Image Transmission Signal.

Is this a hardware issue or do I need to rebind the transmitter. This was just working last week after I perform the latest update.

Also the light above the SD card slot is blining red three times with and without the card in there.

I would reset the drone

Have the drone been involved in crash or hard landing before? If not, please try to refresh the current firmware to see whether it is the misinformation.

No Signal Resolved

I live in Brazil, in the city of São Paulo and my friend has a Phantom 4 Pro that was without transmission of image, appearing in the display "No Signal", he changed and flat cable of the gimbal and No Sign disappeared and the image transmission returned to this is the solution and I believe that several colleagues have the same problem, so exchange your flat cable and solve this problem.
