Hello everyone, I have an LG 23MP48HQ-P with a mainboard EAX65543134. After a power flicker, the monitor only shows the "No Signal" message but goes to a black screen with a brief flash when an HDMI/VGA cable is plugged in. I cannot enter the OSD menu. All main voltages (18V, 5V, 3.3V) are stable under load. I made a backup of the firmware, but it was *after* the fault occurred, so my backup is likely corrupted. I flashed it back with no change in behavior. I can only find the firmware for the 24M38H model online. Could someone please share a working firmware dump for the 23MP48HQ-P?...
