Windows 10 laptop start up screen black

Question

I went camping for a week when I returned my start up screen was black instead of having a picture on it. In addition various apps are also reversed instead of black lettering on a white back ground it is white lettering on a black background.There is also a purple border around the screen. Tried resetting defaults, removing battery for a few mins then reinstalling, they did not help. Any help would be appreciated.

Try this from the Windows Support website:

If you get to a login screen and then your screen goes black or blank, try the following actions:

Action 1: Try a Windows Key sequence to wake the screen.

If you have a keyboard connected, press the Windows logo key+Ctrl+Shift+B. If you’re in tablet mode, press the volume-up and volume-down buttons simultaneously three times within 2 seconds.

Sounds like you've somehow enabled color filter, which is typically used for those with vision contrast issues.  Check WIN ease of access setting? I'm on my smartphone, and not good at touch typing, unable to give more details.

Screen is not completely black or blank, everything works only background is black and lettering is white.

If your screen looks like below, then high contrast is enabled. You should disable it as the keyboard switch combo can accidentally be pressed? Which is likely what happened in your case?
