I have a black screen. What do I do?

First check to see if the computer is on. Then see if the power on the monitor is on. Check the power cables to make sure they are all connected properly. If the power cables are connected to a power strip, make sure the power strip is on and plugged into a jack. Test to see if the power strip went bad by plugging it into a different jack. If everything is right and you continue to have a black screen, then please contact us.
