Video Scope has turned mostly black and white

Not sure how this has happened but my video scope now is all grayscale. When it turns out it starts or color and then within half a second has switched into just greyscale. Any ideas?

Since you are seeing color when you first turn it on, the Video Scope is working as it should. It is likely that the display device you use is changing the display to greyscale.

If you are using a projector with the Video Scope, it could be that there is a 3-D setting that needs to be turned off.

Can you try another display device? Thanks
