Iíve owned and used this for many years as apart of my parents portrait business .

The business is gone but I still have this gem.

In any event I always had issues with the box dropping a color forcing me to power cycle

In the last few years Iíve lost the ability to switch video inputs off RGB

Has anyone fixed one of these?

The inside is a big sandwich of PCBs, looks like a terrible mess to dig into.

Ah well maybe someone has found an easy fix
