Atik 314L mono seems to output inverted ("negative") images

[Astro-Andy]

Hello

 I have an Atik 314L, which until recently has given me good performance. Testing some new equipment, I found the camera "doesn't seem to see" anymore.

It will give me the same grayish appearance as if in a lighted room (or shooting flats). It doesn't darken when I close it off,  brighten when I shine a light on it., nor change with 1, 3, 5, etc. seconds exposure (day & night)

Recently having tested OAG focusing, my thought was maybe it had something to do with this, and had taken a 5-10 sec. long full-dark exposure to "reset it).

I've also used different cables, and different computers, checked the settings in Artemis (also reinstalled drivers, no dice.  Nothing untoward has happened to it.

This testing was under a full moon at 1 second exposure time. During the day, I seem to be able to get inverted pictures (like negatives) at 0.001 seconds.

I have attached a few screenshots. Any advice would be appreciated.

Any advice would be appreciated. Below is a screenshot of how it  looks.
