Citroen C4 flashing screen

[Amugus]

Hi,


I have an issue with a flickering screen/display. All parameters are flickering. I connected a diagnostic computer, and there are no errors. I ran screen tests, and during the tests, it looks stable and nothing flickers. Can someone guide me on where to look for the problem?

I would always suspect the battery voltage. If possible, put an oscilloscope on the supply voltage.
