MacBook Air A1466 no picture

[rtstorm]

Hello, i got this MAcBook Air A1466 (820-00165A) that was spilled by the whiskey :-)

After that the laptop worked but it wont charged the battery. When i disassemby then it wont boot at all (fan spin, cpu and M.2 SSD get hot), no picture. I check board under microscope but there was no sign of water damage.

I found schematics and boardview but dont know where to start? Did mess something up when i open it.

No backlight? No image? No chime? Activity LED of USB drive not blinking? PRAM reset not working?

And one question also, if I replace the whole board will it work with the old M.2 SSD? Is it ok just to swap with the same motherboard, do I need to do some reinstall or something?

Measure voltage on PPVCC_S0_CPU and PLT_RESET_L.

If the SSD has High Sierra (or newer) installed, the filesystem will be APFS (rather than HFS+), so the board requires a firmware update to boot from it. If the board doesn't have the update it'll not show up in boot menu. Easiest way to apply firmware update is to reinstall High Sierra (or newer) on the SSD.
