Digital clock stuck on auto. Was flashing intermittently for a while when I turned it back on after turning off power when went away. Tried all combinations of buttons ie 1 & 2 together, 2 & 3 together and pressing plus minus etc., to re-set. Can't get clock to set time. Stuck firmly on 0.00 auto. Aaaargh !Can you help?
