Failure of LED Backlights
My monitor's screen still shows a faint image when viewed at an angle or with a bright flashlight, but the display remains completely dark during normal use, indicating the LED backlight has failed while the LCD panel itself is still functional. I have already tried reseating the video cables, testing the monitor on another computer, and adjusting the brightness settings in the monitor's OSD menu, but none of these steps have restored the backlight, so I'm hoping someone here can suggest a potential fix or confirm whether this is a known issue with this particular model.

Since you've already tested with another computer and reseated cables, the issue is most likely with the backlight assembly itself.
The exact location and values of fuses, test points, and components vary greatly by model. Searching for your monitor's exact model number online can provide a schematic that is invaluable for this repair.
