Hi all,
My monitor no longer works. There is one component that burned.
The monitor is an Asus VE276Q.
Can you identify this component ?
The reference is something like LT2124 631006 if i see it right !
Thanks

I'm guessing it's a 100V, 3A Schottky rectifier (B3100B ??).
Similar to ...

Page 14 of the datasheet for the MP3389 shows a B180 diode:

Thank you very much. You are great !
I found two components :
One is a SMC case with a 200pF capacitance while the other one is a SMB with 105pF capacitance.
Here are the links :

What do you think should i try ?

I would use whichever diode has the correct dimensions. Check the output for short to ground.
