Emax

get a continuity tester with bell ring test the contacts on the back of the master switch

push the master switch button if it rings the switch is good

if not the switch is bad 

did you put the contact spring back in the correct way

  check for cold solder joints on the back as the pads copper plate is week
  and can crack

  is it a light green board or dark green

  the light green boards are the worst

  It sounds like two different problems.

  The masterbutton can be dirty (bad/dirty pad). Maybe a cleaning of the
  underneathside of masterbutton with some alcohol will work. As long with the
  contacts on the printboard.

  What do you mean with the emax is not being lit? The screen is not lit or
  the LED's don't light up?

  Frank
