I purchased a used SR12 rack for cheap (like, super cheap..), and it has a CEM Classic in it. The CEM appears to be failed -- when I power the rack, the phase lights come on and the LCD lights but never displays any data. The fan at the top of the unit comes on full speed, and that's where it sits -- never outputs anything to the LCD.
Two questions.. first -- this IS likely a failure mode, and not some odd configuration problem, yes? And second, is it worthwhile to contact ETC? Do they repair CEMs, or should I be looking on the used market for a replacement instead?
Thanks for your help.. This is my first forray into the world of Sensor racks :-)
