Best Fix
To fix a dead backlight issue on your LG Ultragear Monitor, the best course of action is to replace the faulty backlight with a new one. However, before going down that route, it is essential to rule out any other possible causes, such as loose connections or driver issues.
Step-by-Step Instructions
1. Turn off the monitor and unplug it from the power source.
2. Carefully remove the monitor's bezel, which is the plastic frame surrounding the screen. Use a small flathead screwdriver or a plastic pry tool to gently separate the bezel from the monitor.
3. Once the bezel is removed, locate the backlight assembly. It should be a long thin strip located at the top or bottom of the monitor.
4. Check for any loose connections between the backlight assembly and the monitor. Ensure that all cables are firmly plugged in.
5. If the connections are secure, examine the backlight for any physical damage or defects. Replace the backlight if necessary.
6. After replacing the backlight, reassemble the monitor by snapping the bezel back into place.
7. Plug the monitor back into the power source and turn it on. If the backlight was the cause of the issue, your monitor should now function properly.
