What’s my issue: I/O Board, I/O Board Flex Cable or Logic Board?
Hi guys,
My MacBook stopped charging one day, and the Apple store said it was due to corrosion around the I/O and/or main logic board and likely there was no hope to fix it. I was told it was probably moisture got drawn in through the fan... to clarify, I’ve never spilt anything on it.
Anyway, I decided to try repair it myself as it’s out of warranty and I got quoted £550+VAT for the repair! I’ve dismantled it completely and carefully cleaned all the components with 99.9% isopropyl alcohol. I did notice some slight corrosion on the underside of the logic board. After drying it out, I’ve reassembled it.
It still won’t work, however I’ve noticed that if I plug in the MagSafe charger (no light shows) and unplug the I/O flex cable, the fan runs and the computer starts up and I get a weird screen (will try upload a photo).
But with the flex cable connected, absolutely nothing.
Long story short, can I determine if the damage is to the logic board, the I/O board or the I/O cable?
Thanks,
Billy
Update (02/18/2018)
I've managed to get my MacBook to turn when plugged in and the I/O cable is not connected. I still get no light on the Magsafe charger, and the computer is running slow with no audio etc, however I can still use it pretty much as normal. As soon as I connect the I/O flex cable, the computer turns off. Likewise when I disconnect the power, it does the same.
Does this sound like an issue with the I/O board itself perhaps?

Es esta una buena pregunta?

OK, not sure it's showing you the Bluetooth mouse or trackpad. Is your keyboard and trackpad not working?

Correct. Presumably this is because the I/O flex cable isn’t connected..?

No, the I/O cable does not effect the onboard USB hub (USB2) for the keyboard & trackpad.
