Examine your cable to determine if it’s damaged. Check the cord for signs of wear, such as fraying. If so, try a different cable. Also try your cable to see if it works on other monitors. If it does not work on another working monitor, your cable is likely faulty.

If the dead pixels still persist in the display, the monitor will need to be serviced or replaced. If your monitor still has a warranty, visit Samsung’s warranty claim site to request a replacement:

Your monitor doesn’t receiving signal from either the HDMI or VGA Cable inputs, or both.

Ensure your cable is either an HDMI cable or a VGA cable, as the Samsung ‘S27E510C 27” Full HD Curved Monitor’ only accepts signals from these two cables. If your cable is Mini HDMI, DVI, or any other cable, you may need to purchase one of the supported cables or an adaptor with an HDMI or VGA head.

Examine your cable to determine if it’s damaged. Check the cord for signs of wear, such as fraying. If the cord is intact, then check the plug of either the HDMI or VGA cable and ensure all the pins are intact, as it only takes one damaged pin to affect the signal. If the cable doesn’t show signs of wear, then test the cable by connecting it to another monitor or display, as it’s possible for the cable to be damaged internally. If the cable displays a signal on another monitor or display, and your drivers are up to date, either the input ports are defective or the motherboard may need to be replaced. Visit the replacement guides for instructions on how to replace these parts.

Inspect both input ports located on the back of the monitor to ensure there isn’t any debris blocking a successful connection. If there is any debris, clean the ports by using a can of compressed air. If you have installed the newest drivers and the monitor still doesn’t display a signal after connecting a cable to either or both of these ports, the input ports or the motherboard may need to be replaced. Visit the replacement guides for instructions on how to replace these parts.

If your Samsung ‘S27510C 27” Full HD Curved Monitor’ is updated with the latest software, your cables are working and supported by the monitor, and the ports on the monitor are clean, then the motherboard might be faulty. Even the introduction of the smallest foreign objects like rust, sand, insects, water, or static electricity can permanently damage a monitor’s motherboard. Visit the replacement guides for instructions on how to replace the motherboard.

Monitor will not power on when it used to

In order to turn your monitor on, the jog button on the rear of the monitor must be pushed in. Press the power button to turn on the monitor. If the monitor does not turn on, press the power button again twice.

Reach around to the rear of the monitor and ensure the cable is securely connected. If the power cord is connected at the back of the monitor then verify that the cord is plugged into the wall outlet. If the cord is not plugged into the outlet, plug the cord into the outlet.

Plug a different device into the outlet to verify the outlet has power. If the monitor is plugged into a surge protector, ensure the toggle switch is turned to the “on” position. Or try plugging the monitor directly into the wall. Refer to the troubleshooting guide for your surge protector for further information. If the outlet does not have power refer to a troubleshooting guide for restoring power to the outlet.

The power cord may be faulty. Similar to previous examples, try using the power cord on another monitor that is known to function properly. If the power cord does not work on the functioning monitor, your cord is faulty and must be replaced.
