[QUOTE="techiesteve, post: 1828131, member: 98520"] I usually disconnect circuitry that isn't essential to the MBA booting up, then attempt to boot from a known good external USB device. Disconnect the camera connector, AP/BT card and SSD. The I/O board and cable wouldn't cause your problem, so no need to swop out. If not booting from an external boot device the logic board has likely failed. It's expensive if fitted by an ARS or AASP. I replace quite a few, most are simply dead though, not with your symptoms.
