Flickering display on artisan controller

Hi as seen it is similar i think to thin lines and flifering display on Snap 2 display. However mine is the 7 inch display on the Artisan contoller. Also it seems it is not regognising my rotary tool module. i have plugged module directly into controller, still hgave same result. A friend has taken my module to plug into his snapmaker for further trouble shhoting. has anyone had similar issuues

I have never read about defective displays on the artisan but maybe I missed..
