I want to repair the logic board because the backlight does not light

MacBook Air (13 inches, beginning of 2015) MJVE 2 J / A

Liquid crystal is not displayed even when the power is turned on, but it is displayed as external output.

When you replace the normally displayed display with a different display, it will be displayed.

There is a problem with the logic board, but the fuse never burns.

I can not find a suspicious part.

Could you tell me?

@rukiano does this "When you replace the normally displayed display with a different display, it will be displayed." mean you can see your desktop when you replace the display with another display?

Nobody can tell from pictures what’s working and what not, unless it’s burnt or charred. You’ll need to dive into schematics diagrams and test components and lines. Fuse seems ok but is out of center as if already replaced before.

Well....sometimes it's pretty clear (The tantalum capacitor is short-circuited and I would like to replace) how the magic smoke escaped... :>)
