Hi mon2! Thanks for the input. Apple only mentioned the TouchID which I replaced as well.

I've also thought that the LAS might be the issue so I disconnected it - under the assumption it behaves the same as on an MacBook Air and defaults to „open“. Should be like this shouldn't it? Backlight remains off.

backlight cabeling has been reset twice - so it should be ok.

Hi there. I am currently trying to figure out if I am undergoing the sunk cost fallacy.

I’ve bought a very cheap MacBook Pro 14 A2442 off eBay. I did some checking and the symptoms were pointing towards a NAND failure.

After some consideration I got an original logic board from Apple as an replacement. However after installing I have no backlight.

I can see the Apple logo if I point a flashlight at it but the MacBook seems to be going to recovery mode.

anybody have an idea of what’s up here? Is the board dead on arrival or is my screen...

I am from Germany. I sometimes feel the sudden urge to get some broken Apple products off eBay and try to fix them.

I have read here quite a bit and finally I’ve created an account
