Can someone take a detailed photo of the burned parts on the downside surface of this dell's monitor  PSU Ilpi-395 V.a 491a012f1400h03 ?

New one for just 11 euro:

They seem to be 2R2 resistors, bu when these burn is due a major failure, so check the transistors, diodes, etc.

I have already ordered one from AliExpress thanks.

Yes, I am pretty sure that all neighbor components have burned, I was just trying to recognize some of them until I receive the replaced one.

So it looks like a 3-terminal mosfet with some high voltage on it, and was it 2 source resistors in parallel that got toasted ? Do you know the supply voltage for the mosfet ? The gate drives on a lot of these types of things are all pretty generic, and the same.

Was it a main's powered Dell, so with some internal step-down type converter, or did it have a power pack ? Or was it a mosfet in a latter stage, running the backlight voltage rails ?

Oh nevermind I didn't look at David's post pic with the main's plug.
