I'll let you know of some possible reasons for this, but I might need more information to go off of. I'll just list off my thoughts:
1. The chassis is just not getting power: It isn't plugged in, that particular outlet is bad, a surge protector is not working correctly, etc. You mentioned moving the chassis, does it work back in its old location?
2. There are no modules plugged into the controller: I don't have a 1002 to check this, but I know that the 1006 will not power on unless the minimal load is met... meaning it needs to have a module or controller actually in the chassis.
3. Too much power draw from module: If a pin was bent somehow causing a short to ground, that could be a possible problem. Or, a particular module just might have issues by
itself. What do you have in your chassis? Try removing everything but the controller. If it boots up, then you can shut down and insert different modules to isolate the problem.
If none of this helps, let me know and I'll see what else I can find out. Any information you can provide would be great. I hope this gets worked our before Thursday.
