How to Troubleshoot LCD Monitor Problems


As it goes with technology, sometimes you'll come across problems with your LCD monitor. Whether you're using it for video games, a work PC or recreation, a malfunctioning LCD monitor can be a distressing and expensive fix. But before you take it in for replacement or repair, try troubleshooting your monitor to see if you can save yourself some stress and money. Many problems can be resolved in a matter of minutes with little to no effort.

  • Check the cables attached to your monitor and make sure they're connected properly. Double-check the power cord and make sure it's in securely. If you have any VGA cables attached to the monitor, make sure they're in tight and that the screws on the cable are attached. Check to make sure the other end of the cables are attached to the device connected to the monitor as well and that the monitor is properly plugged into a working electrical outlet. Many problems are resolved by tightening connections.

  • Make sure your monitor is powered on and set to the appropriate channel. Monitors with multiple inputs have a channel for each input (such as HDMI, VGA, DVI-D and S-Video). Change the channel according to the monitor's user manual and power on the device connected to that input.

  • Move the mouse or press keys on your keyboard if your PC monitor has gone blank. Sometimes monitors go into a sleep mode to save energy if left inactive. Using the device attached to the monitor should wake it back up.

  • Adjust the monitor's display settings according to the user manual. Changing the brightness, tint, contrast and other settings can improve picture quality if you notice strange colors or a dim picture on your monitor.

  • Troubleshoot the device connected to the monitor. Sometimes the problem isn't with the monitor at all, but with the device connected to it. Do this in accordance with the device's user manual.

Tips & Warnings

  • Avoid problems by reading the user manual of any device or LCD monitor before use.
  • If you notice further problems, after these simple fixes, contact the manufacturer of your monitor or visit its support site for brand-specific troubleshooting options.
