My Macbook air just boots to a white screen no apple logo and when i try to reinstall os
none of the Boot key commands work. Maybe it overheated and needs a reflow?

Got it Diagnosed turns out the lvds cable had some broken wires where the hinge on this machine was broken with the bad lvds cable CONNECTED TO THE LOGIC BOARD i was getting a white screen with no apple logo and the macbook air would not display anything other than a white screen even with trying to boot to a usb holding option.
THE FIX:
i disconnected the lvds cable from the logic board because even when i tried to use an external monitor nothing would happen with it still connected ( wires being broken must have grounded the video signal or broken a feedback loop?) as soon as i disconnected the lvds cable from the logic board and tried an external monitor again i got a BLINKING FLASHING FOLDER ON THE EXTERNAL MONITOR SUCCESS!!!
i was even able to boot to a usb (in order to do this on a macbook air you must disconnect the hard drive cable from the logic board)
I HOPE THIS HELPS SOMEONE

Most likely a bad hard drive. Try booting from the original system installation disk or an external USB source.

there is no hard drive in the mac at the moment i want to make sure this machine will work i tried booting from usb but when i hold option nothing happens it just stays at the white screen like there is no video but a backlight
Make sure the external drive has a system that will work on this machine.
it does it has el capitan works on my other macs
What is your EXACT model?
