iMac 4K 2019 Logic Board schematic

[jpreza]

Hey guys,

Looking for schematics for an iMac 4k 2019 model. For the life of me, I can't figure out why the display will not work. Everything is connected correctly, I don't see any caps or resistors that are damaged. I even swapped the display from another iMac 4k 2019 model to test it, and that display won't work either.

There are 5 diagnostic LEDs and only 4 light up. The last one does not.

Any help with schematics would be awesome!

Thanks! Yes, I do. The board number is 820-01237. There is also a variation of this board 820-01237-A. Either one would work for me!
