LG 25UM58-P: Monitor doesn't work, burnt component

Tue, 20 Jan 2026 06:42:27 -0700

Hi, bought this monitor used, supposedly working but with no charger. Bought one and... nothing happened. I tore it down and found a burnt component that I wasn't able to identify (from lack of skill and a little too damage). Can anyone please help out? I bought it for about €20 alongside another monitor, so I'm not mad, but if I can try to fix it for a small price, I'm happy to try, and broken for broken...

P.S. First image is mine, a close up of the burnt component. Second one is from the teardown here on ifixit, to locate the component easier.

LG 25UM58-P: Back light comes on but nothing shows on display

The back light comes on but shows nothing on display. I’ve tried different HDMI cables in different ports using different laptops.

It was working fine, then made a pop noise and stopped. When I try to use it, it makes a loud noise of a short while then stops.

LG 25UM58-P: Knob dropped, and doesn't seem broke.

The knob used to control the menu dropped. I don't know how to mount back. Came out some pad that a think is to make contact and the button itself.
