Citroen C4 flashing screen

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?


Citroen C4 1.6 HDI 2007.
 
I doubt you need oscilloscope for this repair. More likely you just need to open it and check the connection for the screen.

Using a scope on the external supply will just be a waist of time unless the entire unit is cutting on and off and not just suffering a flickering display. These are designed to handle a pretty wide range for input voltage since its automotive and then it would get better regulation inside. IMO you'd most likely get some fault codes if it was anything power related as well (external or internal).
