Hello

i got A1708, customer said while opening the lid, sometimes it works sometimes not. I tried and most of the time it's black with no apple logo after chemie.... but sometimes it starts, I see apple logo, I see login prompt then it stops.. black screen but Mac still on.

I install motherboard to another A1708, it's working fine.

When I connect external display it works.

The screen looks nice, there's no scratches... customer said Macbook didn't fall.

Could this be related to the little board between screen an motherboard ?

Very likely flexgate issue.
Inspect backlight flex on T-CON.
Be sure that is the problem, before going on to fix it.

You can try the fast solution; confirmed as working.
