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 sayLeave a comment:
