Here you go, not easy to find...recently purchased to repair the same. We were 99.99% done without the aid of the schematics - had a shorted tantalum that we found through sub-dividing the logic board regions. Found the shorted tantalum, removed it but board would not power up. Embarrassed to say that the dual mosfet we removed for the 5v rail was not soldered onto the board properly - it just took much more heat and flux to place it back. While we were checking against these schematics, the meter probe shifted the improperly soldered mosfet. So, in a way, the schematics helped

The board worked perfectly after this reflowing of the dual mosfet.

thank you for board view file
but
I have issue with 2019 iMac. all works fine except for speakers crackle during the chime when turning on.. unsure what the issue is, but have diagnosed with known working speakers, cpu swaps, re-casing board and even replacing with known working firmware chip but still have not found out the cause, hoping these schematics will help. if you have any other idea please feel free to say

hello, i would check all the capacitors a resisters around the sound socket under the on the right hand side. sometimes if you remove the socket #with tool you maybe damaged an capacitor
