Reverse Camera works with Key at ACC but not with engine running

HI,
I have Pumpkin 7" android 5.1 and installed it in my AUDI A4 (purchased on amazon ref.205-6547017-0089933) i installed the camera in last couple of weeks
.
i have connected the camera to the Cam in RCA connector and the Orange/Black reverse signal detect wire, and the camera is powered by the reverse light.
when i turn the key to ACC and put the gear into reverse the the head unit switches to the reverse camera view (great picture very clear)
but when i have the engine running and put the gear in to reverse the head unit picture changes to some times a green screen & sometimes black screen with orange triangle, also if i try with key to ACC first (see the correct view) then start the car and try again I get a still image of the view i got previously.

i have checked the wiring and there is no short circuit or loose wires.
and assistance you can provide would be great

i have taken a couple of pic's for demonstration if you need any more information to help find the problem let me know

HI ,
thanks for the quick reply,
I thought it had to be a power issue.
I will give this a try at the weekend (weather permitting) 8-)
cheers
