    MacBook Air A1466 820 - 00165 -A Restart one time, No Display.

    NO Green Light neither Orange light. Due to fungus the R5100 was bad. SMC_RESET_L pin is okay of the resistor but the PP3V42_G3H track gone. So I have to connect by jumper wire with the 100K.

    After that the adapter light is on, first green to orange. Motherboard fan starts to spin. All the power supply voltage is there. But No Display. And I also noticed that after 20 to 30 seconds the MB restarts and gradually FAN Speed increasing. BUt NO Display.

    But interesting part is that after replacing the R5100 the display have come two/three times. So I have tried ME clean, changing the BIN file with known good bios file. NO luck. Symptoms are same.

    Any further guide is appreciated. If there is any thing you want to know please tell me.

    First thing to check is condition around the SMC, it's often where I start on most jobs that have corrosion. Reflow, reball or replace.
