Hello,
I am an avid fixer, whether it is caused by my own ignorance in damaging my equipment lol or fixing someone else’s tech. I love to restore something back to a usable condition. I was Electronics technician with the Navy for a while and I am also trained as a solder technician. I have replaced SMT chips on logic boards to get them back to life, like the 12” MacBook they released only to have it work for two weeks and die. The power controller kept dying in it. I have foxed phones, computers and iPads but I love to come here because there are more than just resources to diagnose your problem. There is a commmunity of people trying to fix their gear who can help. I appreciate what I have learned here and hope I will be able to provide assistance to someone in the future

Hi I'm Dan. I have an iMac Pro 27 A1862. Looking for schematic for power supply. Suddenly lost power. Changed the power supply, it's possible the new power supply I received may not be providing full power. I need a pin out on the power supply to test voltage. Has anyone experienced this issue. I would appreciate any information. Thank you.
