How to fix if samsung monitor display is blank

• Ensure the monitor is turned on by checking the panel light at the bottom. Press and hold the power button for a few seconds if necessary.
• Verify the power cord is securely connected at both ends.

• Check the main socket by connecting any other device like iron or any other appliance.

• If the other appliance works correctly, there might be an issue with the monitor. Contact Samsung customer care for assistance. Otherwise, proceed to step 2.

A loose or faulty cable can cause a blank screen, even when it seems connected. Replace the cable if it's damaged. Refer to the user manual for guidance on choosing the right cable.

• Most monitors automatically detect the source sending a video signal. Manually selecting the source may sometimes be required. Use buttons on the monitor, remote control, or the on-screen menu to change the source.
• To select the correct source, press Home > Menu > Connected Devices > Sources (e.g., HDMI).

* This function may not be supported depending on the model or geographical area.

• Access the Menu/Home option on your monitor or go to Settings (All Settings) > Support (System) > Self Diagnosis (Device Care > Self Diagnosis) > Picture Test > OK. Do not turn off the monitor or change the input source during the test.
• If the self-diagnosis fails and the screen remains blank, contact Samsung customer care for product repair.
• If the self-diagnosis passes, there's no issue with the monitor. Consider replacing the cable or contacting the external device manufacturer's service provider.
