AW2521HFL, screen issue

Question

I was playing my game one day, and the screen, out of nowhere got dim in one spot on the right side going vertical. I factory reset and reset every setting and nothing worked. Then I looked online on how to hardware reset, and it said to unplug the monitor. Hold the buttons on the side. While holding the button, plug the monitor back into power. Then wait. I did that and the monitor fixed itself. It was no longer dim. It worked for a few more days then it did it again, so I tried the same method except now it like bypasses the reset. It turns on like I never unplugged it. I don't understand how to fix it. I will attach a picture. Pls help

@HelpMePlsSir​ Run a hardware diagnostic as per page 63 of the manual. This will determine if it's a hardware error or not. To me it looks like a hardware failure of some kind.

@Vanadiel​ The white background image is from the self run in diagnostic. If it's a hardware issue, could it be due to old capacitors? Would I be able to simply fix it myself or should I buy a new monitor?

It looks more like a failing LED in the backlight -- not easily repairable, particularly given the low cost of 25' monitors these days.  It would cost more to repair than replace the monitor.

@ejn63​ I agree on that diagnostic as that is what it would look like.
