Macbook Air A2681 M2 2022- No Backlight After Liquid Spill

[Jmandersma]

Hello, I'm a novice when it comes to board repairs, and in identifying where is the first place I must start testing for any particular readings or issues.
I've got a macbook A2681 M2 2022, which have had a liquid spill, it comes on but there's no backlight, when a light is shine on the screen I am able to see an image, and it also works with an external monitor.
The connector on the motherboard (I think JP600), where the LCD is connected, has a burnt pin in it.
Is the burnt pin the issue on the connector or is it something else why the backlight isn't working?

First of all, welcome to the forum!.

Is that pin 57?
You must replace the connector and probably video flex is also damaged.

Thank you very much for the welcome.
I think it's pin 57, based on where the burnt is located.

Then do what I said.
Finally, check diode mode to ground on backlight output; w/ and w/o LCD connected.

Any ideas where these connectors can be purchased, if there are no access to donor boards?

Get the connector code from schematic, then search with that code on Internet.
Also check on older models (M1, T2) schematics...
