Also, because you modify setTime, you need to declare
it as global.

So the function should look like:

def displayCountdown():
    global setTime
    lcd = "{:02d}:{:02d}".format(*divmod(setTime, 60))
    timeString.set(lcd)
    setTime -= 1
    if setTime > 0:
        root.after(1000,displayCountdown)
