Schematic : DAOP5EMB6E0 REV:E
I have tried manually flashed the bios, also tried hp bios recovery tools to recover the bios. But no luck. Display is not coming, 3 to 4 times recovery display is coming if I tried to recover by pen drive[win+ B]. But after restarts it goes to dark screen and a light is flashing after a certain time in the display + fan speeds increasing and decreasing. I have tried almost every bios for this motherboard avaiable in the internet.
Any help or guide to proceed?

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,... -
