What's most remarkable about this was that we got color out of the TV with only a green input.
This makes me wonder if one or both ends of the connection think that they are dealing with Composite video.
Two times we got a mostly black screen with a deep purple color across the top that turned to black by halfway down the screen.
If this is "walking" up the screen, it suggests some sort of gross ground loop or power supply issue.
