No charge, no startup after screen change ##SOLVED##
After I changed my LCD assembly on my MacBook Air A1466 2013 I am not able to either charge it or power on. I first powered it on but the screen resolution was wrong. Seems it tried som 1650 resolution. At least the resolution was too high so I had a black area at the top and bottom. I then did a restart and the display showed correct resolution.
Then I chose a restart but it did not start up. I noticed it was not charging but I had forgot to attach the I/O Board Cable. So I attached it. Still no charge light and it will not power on. I tried different things, reset SMC disconnected cables and connected again. Suddenly the charger lights red. Still no power on. Now there is no light on the charger. Tried again SMC reset, different chargers I know work, cleaned the charger port. Tried to short the start pads on the logic board. Tried to disconnect the battery. Just nothing happens now.
Could this be a faulty I/O board? And why does this happen now since everything was flawless before the LCD change. No problems at all besides the broken LCD that I now have replaced. And the first time I confirmed the LCD was ok.
Thanks for all inputs guys! I took this to an Apple Service Center and they found the I/O board was the problem. They did in fact replace the I/O board for free! That is the benefits of living in Norway. We have a consumer law that covers anything that should last 5 years (like computers) for 5 years from purchase. Of course Apple never mentions that "Sorry this is past your 1 year warranty". Then I mention the consumer law warranty and they fix it. I have used that for anything from phones, shavers, water boilers, etc.
