Macintosh II doesn't power with button or keyboard, new batts & caps

Recommended Posts

Hi guys, I have a Macintosh II that I can't get to power via the button on the back or via the keyboard.  I have already replaced both batteries and the capacitors on the logic board.  The system does start up just fine using the white wire from PS-3V battery-ground trick.


This is the version of the logic board with axial caps, not the aluminum radial SMT ones.  The board itself is clean with no visible corrosion.


What else could be the issue here?
