Hi, This is really frustrating, my macbook air early 2015, is working fine one day and next day it flickers and I tried to reset smc but later on it, it was shut down completely. After showing to Apple store, due to moisture logic board replacement was suggested at almost 80% more expense which is lot on this dummy. So I shown it to some local apple experts, one has told me that main ic is damaged and somehow it took him 3 months to finally atleast start my laptop but at the cost of wifi, audio, battery, camera and Keyboard lights. I ran macbook diagnostic and also clicked the picture as attached.
Can someone suggest or help me please
PFM006 is a SMC error. I don’t see this condition would effect your WiFi, Audio, Battery, Camera or keyboard backlights. This sounds more like something more major happened to your system. Did you have a liquid spill at some point? At this point I would need to see some pics, you stated you had posted them they are not visible. Review this guide: Adding images to an existing question If you hadn’t please take the logic board fully out and take detailed (focused) pics of both sides. Update (07/13/2020) Sadly the logic board did get wet and does have a bit of corrosion damage. You’ll need to clean it with a soft toothbrush and 85% or better isopropyl alcohol. Compare with the guides images for the areas that need cleaning.
