Do you get anything displayed on the screen if you diconnected the MK4 unit? if YES, then this should be how you troubleshoot. (and would exclude the MK4 from the issue if the scramble could be duplicated...obviously)

As I recall the screen has the video drivers in it....

I had a video issue on my E39- wound up replacing the screen (warranty). Red drivers died, so screen showed distored images.
Keep it as simple as possible...but no simpler.
