IMAC (RETINA 5K, 27-INCH, MID 2015) Doesn't Power Up

[NerdSurgeon]

Hey,

I have the above in for repair and have replaced the power supply but this hasn't resolved the issue. I have LED#1 lit when power cable is connected but no other LEDs come on when power button is pressed. Is there any other options I can try before removing the logic board for diagnosis?

Remove the board first to diagnose, inspect the board especially if somebody else has tried to fix it....
