Hi Randy and thanks for that.
If you are sure there is power to the treadmill then the problem is going to be the main console. These will fail as many other electronic componemts will if left unplugged for that long. Also when electronic components are plugged in for a long time and the parts in the supplies are warm, when you unplug them there is always the possibility that it wont work. It is actually very common with these as well.
It is best to keep them plugged in all the time even when not in use.
You can replace the console and I will help its actually easy to do if you have a few basic hand tools and follow the instructions I will give.
For one thing before taking any wire clips off the board, take a pic or two so your sre where it goes ;-)
The best place to get that main console is Treadmill Doctor:
