Hi, am sorry to hear it. There are possibilities that unwanted Potential or Static energy might have got stacked up in the unit. Kindly try Power On Self Test by following the below steps.
1) Turn Off the monitor and unplug all the cables from the monitor .
2) Press and hold the Power Button of the Monitor for 30 seconds approximately and then release the button.
3) Plug the cables back in and check.
