Bachmann EZ command (kaput)

[errolflynn737]

Does anyone know how to reset the EZ command system?  Mine stopped working.  It will power up, but won't control locos.  I'm an experienced modeler and I've tried everything.  I have good, clean track....clean wheels....everything was working until it stopped.  I don't need a lot of suggestions, just a knowledgable answer or if I should send it into Bachmann.  Lifetime warranty, I hope.
Thanks
John
