Monitor won't turn on
If there's no indicator light displaying, check the power switch, check the power cord, and test
the outlet. Unfortunately, this basic troubleshooting is the only way to try to fix the issue
yourself. If this doesn't help the monitor turn on, then it will need service.

1. Check for a power switch.
Some older monitors have a power switch on the back, similar to the power switch on the
back of a desktop computer. This must be switched on before the power button on the
front will work.
2. Test the outlet.
Unplug the power cord for the monitor from the outlet and then plug something else in
the same outlet (like a lamp) and make sure it's still working.
3. Plug the power cord back in.
Remove the power cord from the monitor as well, and then plug it back in to both the
outlet you tested and the monitor.
It's pretty rare for power cords to go bad, but if you happen to have a spare one handy,
you can try using a different power cord as well.
Monitor is flickering
A monitor that flickers, flashes, or blinks is never a good thing. Luckily, the most common cause
for this is a connection issue or damaged cables. Follow this guide to determine if a new cable
will fix the flickering, or if you need to examine the monitor's power source or refresh rate
settings, or perform a system update.
1. Confirm the monitor's cable is connected securely and not damaged.
Unplug the monitor's cable from the computer, inspect the pins for damage, and then
reconnect it securely. Do the same at the other end of the cable where it plugs into the
monitor. You can do this while your monitor is turned on, and see if the flickering stops.

Finally, if you happen to have another cable easily available, you can swap it in and check if the monitor still flickers.
