Try shining a flashlight at an angle close to the screen and check if you can see any images at all on the screen.
They will be ''very faint'' if they are there so trying this in a darkened room may help to see them.
''If you can see images'' then there's a backlight problem with the display.
It could be a faulty LED that fails as it warms up, but given that the LED lights are usually connected in strips in an LCD display the other strips would stay on and there would be dark areas rather than the whole screen, but it might depend on the circuit design I suppose.
You could try using a [link|https://www.amazon.com.au/s?k=led+backlight+tester|backlight tester] (examples only) and connect it to the LED strips power leads i.e. disconnect the LEDs from the power board and connect the tester directly to each LED strip circuit, to see if it is a strip or strips or the power board. The tester supplies the power for the LEDs and not the power board.

It could be either the LED backlights or the power board, but to test the LEDs individually, without a LED tester to be sure where it is, you would have to disassemble the monitor more than you would need to just replace the power board.

Also if it is a faulty LED (or LEDs) sourcing individual LEDs is not easy as there may be a "brightness" difference between the original LED and the replacement, giving bright spots in the display. A quick search online didn't find any LED strips either, but it was only a quick look. If it is a strip then maybe replace the lot as if one has gone then the others may not be far away from failing either. Perhaps there is a part number on the strip which may make it easier to locate a replacement.
The monitor seems to be a fairly new model and a search online indicates that Acer have a 2 year warranty on monitors but this may be different where you are. If your monitor is still under warranty, get it repaired/replaced that way rather than opening it up to find out what's wrong and voiding the warranty.
