Jazzman, you last idea sounds like a good one...
"Finally, when I sit at the radar console, and turn it on manually, and don't have it sweeping, when I push the single sweep button, the scope brightens a bit in a single narrow focus and the unit powers off. Just what I'm seeing from the bridge."
This particular detail seems normal. Unless you actually place the 3D console in continious sweep on the console (not the task bar icons) the 3D display remains in focus mode. It's best not to use the 3D console when controlling the radar from the navbar icons. Use the icons when you are not at the 3D console, and don't use the icons when at the console. They conflict with each other to some extent.
