Had my Phantom 4 pro for over a year and it has worked perfecty... today took some photos.. and the screen was flickering.. and these are the pictures recorded to the SD card... have I got a shutter issue? A ribbon issue to the camera? Any suggestions appreciated... have come home and over exposed parts of the image Raw and JPG to the SD card have these back vertical lines down them..(not zebras on the mobile screen, these are in the recorded RAW image to the SD)
