Looking for Logicboard Schematics to locate F4400 and F8100
Looking for schematics of the logic board of a 2017 27” iMac. Symptoms are black screen at start up and fan at full speed. 4 (rather 3.5) out of 5 diagnostic LEDs are lid but there is 0 signal from the LCD. I am trying to see if i have failed fuses F4400 or F8100 as of the Technician Service Manual. But i cant really exactly make out which components are the right ones. Schematics would help me a lot here.
Thanks!
Can you give us some background on what happened. The more details the better.

Bought the Mac as parts. Looks like the po removed the screen and broke the lvds connector and cable. I suspect when reassembling the connector causes a short. The Mac runs fine with external screen. 4 out of 5 diagnose leds are lid. I tried to measure the fuse today but I am unsure which one is the fuse. Trying to figure out where exactly F4400 and F8100 are and what specifications they have.

Yeah I know f4400 is located close to the connector and f8100 is on the other side of the logic board, but I just don’t know exactly where they are and their specifications
