Report "I have a nordictrack elite 2900. We moved and when we plugged it in it wouldn't come on. No display whatsoever. We left it for a while and when we plugged it in again, it would incline on its own but no display. Yesterday, I plugged it in and it worked like a champ. It was in demo mode, but I was able to run on it. Afterward, I took it out of demo mode and unplugged it. Today, it will not display anything but the fan comes on on high. Is there a fix to this? Can I just put it back in demo mode and run? I have tried holding in the stop and placing key on but it doesn't display anything. Thank you for any help you can provide"
