    Please tell me from which other MacBook model can I get a display to test this MacBook? (suddenly both my displays are faulty from this model! just because they work with boards from 1707 does not mean that they work with native Mac)

    yes I replaced the U9850! Is it worth to change GPU? why not ? This is the same chip as T2! The main thing is to check everything carefully to make sure that it is the GPU! I can’t understand why the Intel graphics don’t work if the AMD fails or vice versa! if some line of U9850 missed 55, then...

    the only damage was on the t-con of two lines! I tried installing it in another case, but that didn’t work either! could the problem be related to PPVOUT_S0_LCDBKLT?!

    I installed the new U9850 and, to my deepest disappointment, the result remained the same! still no picture! We're missing something!
