No display on my ED323QUR

Hi. The display on my monitor model ED323QUR went blank recently while I was using it. It just faded to black over a couple of seconds. The back light is still working, and it powers on/off from the button. There is no OSD, nor boot up logo. The graphics card is working just fine as other monitors are still OK.

As the monitor is out of warranty I did open it up and check the internals. The PSU is showing a good 12v, and there is no sign of blown caps. I managed to source a replacement controller card from a monitor with a cracked screen but it gave the same result.

Any ideas what else I can check to fix this monitor? It was a good monitor when working, and I can't really afford to replace it right now.

    Try to check with the different power cord and check.
    Unplug all wires and the back of the monitor including the power cable and press and hold the power button for 30 seconds and reconnect and check

    Yes, I've tried multiple power cables, no change back light comes on, no image.

    The monitor has been completely unplugged for a couple days now, so I did the 30 second thing, plugged it back in and no change, back light comes on, no display.
