The problem with the green stripes.Leaf aptus 12

[ranger290]

In advance I apologize for my English.

I am writing through an interpreter.
Green stripes appear at any exposure EXCEPT 1.100.
At a shutter speed of 1.200, a green vignette appears. if you make the shutter speed even shorter then the stripes alternate.
The bands look like an old TV.
also a problem with the photo in case of poor coverage. then part of the screen has a different white balance,.
Thanks for the answer.
