How to Repair ‘No Signal’ Error on a Monitor
If your company does not have an IT department, you will have to service your computers yourself when an error occurs. If the message “No input signal” is displayed on the monitor, the computer image is not being displayed on the monitor.
There are several possible causes for this error. To troubleshoot it, you need to find the faulty component, whether it is the cables connecting the monitor to the computer, the monitor itself, or even the video card in the computer.
What causes no signals on the monitor?
- A loose HDMI cable can prevent your computer from displaying the output signal (and vice versa).
- There may also be a faulty monitor cable.
- There may also be a power problem that prevents the monitor from working properly.
- The “No Signal on Monitor” error may be an indication that your PC monitor is ignoring your PC’s graphics output.
