Either the right or the left hand half of the faders on the Eos Standard Fader Wing 40 are unresponsive. Their displays only show the ETC logo and do not display fader information. The LED indicators on the fader bump buttons may show the same indications as the LEDs on the working side of the wing. However, under Detected Modules in the Maintenance tab of the settings in the console shell, the console displays two fader wings, and firmware for both halves of the wing can be successfully updated.

If the above conditions are true, please contact ETC Technical Services or an ETC Authorized Service Center for assistance.
