Hello, i have imac 2015 21.5', customer says that sometimes still was able to turn it on. Openeed lcd, when power lead plugged, green light on ligic board shines.
On power button there are 3.4v, when pressed becomes 0v, when released again 3.4v.
Board looks as clean as new. What would you advice to check next? Is there any schematic?

Thank you
