Test and replace a computer monitor fuse: Lay the monitor on a padded surface and remove the housing screws (some may be under pop-out tabs). Slide the rear housing off. Locate the line fuse typically near the power cord entrance. Remove the fuse from its holder and test it with a multimeter.
Does a monitor have a fuse?
If you encounter the situation where your monitor will not power on, then one potential reason is a blown fuse. The fuse is present to protect your monitor from being damaged in case of a power surge occurring etc.
Why is there no power going to my monitor?
Test the power outlet being used by plugging in another electrical device and verify that there is power. Ensure that the power cable is fully inserted at both ends. Swap with a known-good power cable, if one is available. Verify the exact location of the power light on the monitor by using the monitor’s User Guide.
Why has my monitor stopped working?
Check the power cable If the power cord is removable from the back of the monitor, try replacing it with another power cable. If you still cannot turn on the monitor after trying another wall outlet and cable, the monitor is broken and should be replaced.
