Trouble shooting a blank computer screen
Why do I have a blank computer screen even though it’s turned on? If your computer monitor displays a black screen with no picture when you turn on your computer, the following steps may help you troubleshoot or repair the problem.
The main culprits of a blank computer screen on Windows 10 are a malfunctioning screen, a bad video card or a bad connection. Other causes include a corrupted system file, which manifests with a blinking prompt and a blank screen, a faulty display adapter, or your computerjust crashed due to a motherboard failure.
There may be an issue with the connection between the computer and the screen. First, check to see if the monitor is plugged into a power point and that the connection between the monitor and computer hard drive is secure. If the problem is on a laptop, then you may need to get a professional to fix it as some of the internal wires may be worn. Call us at 800.960.9030.

Monitor is not on
It may seem obvious, but first, make sure the monitor is turned on. If you don’t see a power LED (blue, green, or orange light) on the monitor’s front or bottom, press the power button again. If no light comes on after several attempts, proceed to the next section.
Computer is asleep
If you stepped away from the computer for a bit and returned to a black screen, the computer is likely asleep. Try moving your mouse, clicking the mouse buttons, or pressing any key (e.g., spacebar) to wake it up. If none of those actions work, press the power button.
Loose or improper connections
The following steps help you ensure the monitor is connected correctly to the computer.
Try a different cable
If your monitor is getting power, but you still don’t see an image, the data cable may be the issue. Try using a different DVI, HDMI, or DisplayPort cable with your monitor.
Turn up the brightness and contrast
If you’re able to view your monitor’s settings menu even though the screen is blank, you likely need to turn up the brightness and contrast.
