Black Screen on Windows 10 Issue Top 7 Ways to Fix Windows 10 Black Screen

The problem is not the fix, the problem is finding out which problem of many possibilities is causing the the black screen.
This requires some troubleshooting.
I assume you are using a PC.
The first step is to turn on the monitor first.
Make sure the power on indicator LED on the monitor comes on.
Then boot the PC. Make sure the CPU fan comes on inside the PC.
(If you are running a laptop and the screen is always black, it is usually the flexible cable joining the screen to the main body has broken. A hardware problem)
Does anything show up on the screen?

If no, check the CPU cooler inside the PC.
If it is plugged up with dust and lint, you may have a burned out CPU that will have to be replaced. (A lack of cooling air causes the CPU to overheat and fail when the safety does not work. A common problem.)

If yes, get a Linux boot CDROM/DVD, boot on the Linux CDROM/DVD, and follow the instructions to run CLAM antivirus under Linux.
When the screen goes black during boot, and stays black, the problem is usually a "Root Kit" virus.
You can not remove these viruses with a normal Windows antivirus program. They are too deeply embedded in the system.

This is the start of the troubleshooting procedure.
You really need somebody "on-site" to troubleshoot a problem that is this complex.

The problem you describe is frequently the result of dirty/corroded battery contacts in the camera. Try removing the batteries and cleaning the inside contacts with a fine wire brush, steel wool, or fine sandpaper. Remove any residue left from the cleaning, then replace the batteries. Hopefully all will be well.

If the cleaning doesn't work you might want to check the Kodak troubleshooting guide at:
