I noticed this issue last spring, and this past weekend, switched things around to confirm.
I am not seeing red on my Geneve. Has anyone ever observed a specific color missing to know the likely cause? I pulled up John Strain's schematic from the 9938 to the video port, but have not started testing anything with an ohm meter to see if there is a break in connection yet as I have to find my ohm meter.
Any thoughts on a likely failure? I do not know if the video lines run on a layer below the surface, or if they are visible.
Any thoughts appreciated.
