I have a vision plus with the dreaded black screen issue..my gimbal worked, had telematry, video, pics..but no video feed..i tried installing a second hand wifi modual with no luck..i recently seen a post with a walk through on how to reflash the Nand chip on the wifi modual..unfortunately for me 2 weeks ago i figured i would replace the ribbon cable to see if that would help...bad move..now my gimbal does not work it just beeps...beep beep....beep beep..2 beeps over and over, with a flashing red on tje front of the camera and a flashing red on the rear near the usb... this is the 2nd time i rewired it..the first time  it beeped once over and over with a red flashing light in front with a green on the rear...any help would be great...video link included
