I need to quickly turn the power on and off to my monitor (using a power bar) several times in order for it to stay on. Once it’s on it’s fine. Is there a part that I can replace to continue using this great monitor? Thanks.

I’m suspecting the backlight LED driver circuit needs repairs (main logic board). To verify turn on the display and rest a flashlight on the display at a sharp angle do you see a faint image of your desktop and the icons? If not that then the power switch is failing.
