MacBook 820-00923 identify component

[bios2000]

Hi together

Maybe someone can help me: I have a 820-00923 mainboard (as far as I know, no schematics or board view exist...) that has a small water damage right next to the display connector.

Now I would need help to identify the component that was burned away (I attached two images). Can someone help me with it?


Thanks and greetings

Look at the QFN IC next to the burnt area, take note of the part number. Google the part number and 820- ,find a schematic with the same IC and layout.

Nope, the component is not connected to that QFN. One connection goes to the display connector and the other one disappears in an inner layer.
