I have a MacBook air a1466 (820 000165), after replacing the bios chip, I have green then orange light and, fan spin for a long time but no image, I tried with a flashlight to see if it is a backlight issue.
PPbus_g3h, pp3v42, and pp5v_s4l are present, and 3.3V on u6100 pin 8, also r6115 and r 6130 have been replaced after missing them because of the hot air.since I already know that the MacBook was working fine before u6100 was replaced, can you help me identify the issue?
thanx for your help
