Hello,
I’m trying to troubleshoot the Acer Nitro XV340CK monitor, the issue is monitor turns on backlight lights up but no picture is displayed. At start the restart would help for couple of hours, but now even acer logo is not coming up when turned on. Disassembled the monitor, no physical damage (blown caps or anything) on power supply or main board. Since the backlight turns on it shouldn’t be a power supply issue. What should I look at next on the main board?
