Ok, I've run the console in test mode as per your instructions. All appears as it should and all faders register as they should with the exception of fader #14! When I slide this fader up and down the virtual front panel responds as it should but channel 26 also displays a value. when channel 14 is 100% channel 26 flickers between 42 & 44%!
Since I last contacted you I have experienced a further, far more serious issue with the console. When operating the console for the current production the first 6 cues performed as they should, but then the next cue did not respond although the screen did show the correct operation. On pressing the Master Playback button a few times again, still the console did not respond and then after about 40 seconds or so it progressed through all of the cues. It then behaved correctly for the rest of the production.
When rebooting the console after the production, it did exactly the same thing but when I re booted the following day it behaved impeccably.
However I have lost confidence in the console and reprogrammed the production on my old Jester console which had no problems. Fortunately there were only a small number of lighting cues in the production.
I feel I cannot use the FLX S48 console again now until this is resolved.
Where do we go from here?
