How to find defective parts after coffee spill?
I'm currently in the process of getting a MacBook Air to work again after a coffee spill.
So far, I've already disassembled it and cleaned the components with special electronics/pcb cleaner. Unfortunately it doesn't want to power on and I don't have any idea which part is causing it yet. Here are two things I've already figured out:
- The MagSafe 2 LED is green when connecting it and changes to orange (charging) after one second.
- The MagSafe 2 LED changes when resetting the SMC, so I guess the keyboard/upper case is still ok.
I already disconnected almost everything from the logic/IO board in order to exclude these parts (SSD, speakers, microphone, AirPort/Bluetooth etc.), yet absolutely nothing happens when I hold the power button. No startup sound, no fan spinning, display remains black.
Is there any way how I could find the defective parts or get it to work at all? Unfortunately I don't have another MBA to exchange parts.
Bu iyi bir soru mu?

So, I put the components in distilled water, brushed them with a soft toothbrush, let them dry a few days and literally soaked them in isopropyl alcohol. Waited another two days, assembled the MBA and it finally powered on. Thanks a lot for your help guys!

@angelorecaman - Angelo, I don't think marcel will respond to your request as his last post was over three years ago.
I would recommend you post a fresh question so others see it and collectively we can help you.
