Bright Black Screen Issue with OpenFlexure Microscope Software

Hi evryone,
Bright Black screen appears when I try to use the OpenFlexure microscope software. The device powers on, but the screen stays blank, and I can’t proceed.
Has anyone encountered this issue or knows how to fix it? Any advice would be appreciated!Thank you.

@romromillys, which software version are you using? If you could post the name of the image file that you loaded this would help.
Are you using it with a keyboard, mouse and screen?

A photograph of your setup would be very useful.
