Linn LK 280 on/off button stuck

New to the Forum, so if this is an old question or I am somehow "out of place" , I apologize. Quick question, I leave on all of my Linn equipment to make sure it is properly warmed. Today I need to turn off the LK280 to wake up one channel which had gone out for unknown reasons, to my surprise the button is stuck, frozen in (the on position) any ideas how to get such a button unstuck?
