Hi I did some repairs on this board and I have it running but the WiFi is not working apparently it had a issue with WiFi before it totally died. The connector looks like it was scrapped maybe burned before and I did continuity on connector all pins. All have continuity to there external pins. I also checked continuity from
L3404 pin 1 to j3404 pins 22,24,26,28,30,29 all have continuity.
L3404 has 3.3 on both pins 1 and 2
3.3v is getting to pin 22,24,26,28,30,29
so even though the connector doesn?t look great it still is conducting. I?ve change both WiFi airport and cable of known working units.

Check L3401/73/74 and their continuity with J3401.
Also compare diode mode to ground with similar board.
No hardware detected on System Report?
