SL1S shows no sign of life.

The printer shows nothing on the screen and no fans turn on. I have 1 red led on the power board. I’ve checked the following:

1) Replaced external power brick with one from prusa

2) measured 24V on the light green connector on the power board and on the other end near main board.

3) I measure no voltage on daughter board for the power button. 
4) I pulled the fuse and looks fine but still can read 24 V from light green connector with fuse removed.

What can I do to confirm if this is a main board issue or something else?

Just found a second fuse on main board. Maybe that’s it? I’ll run and grab a 3amp fuse
