My newly acquired Tandy CM-5 monitor has an apparent permanent bright red background when video signal is applied, on multiple systems.
Any idea where to begin investigating this?
The connector itself seems undamaged. All apps and games seem to suffer from the problem, so I'm pretty sure it's an issue with the monitor or cable itself. Tapping on the monitor case and wiggling the display connector on either end doesn't change anything.
