Question My monitor suddenly shows just a black screen ?


Jun 17, 2014
I have a Xiaomi Surface 34 monitor which suddenly shows no picture.
When I turn it on there's nothing, then when I plug in the display port /HDMI the backlight lights up and shows just a black screen.
The repair shops refuse to take it in saying xiaomi boards are not available. When I open the back panel there seems to be nothing wrong with the boards and wires.

should I order a T-Con board and replace it or could it be something else entirely?
