Help with Default to black

[Ian_p]

All, I've read all the threads I can about default settings - but I'm still having issues with an intermittent flash to white when fading between cues. Worse if the fade is more than a second.

FLX S24, V8 software, using playback 0 in a theatrical cue stack. 

All conventional dimmer lanterns are on page 1 and 3 - no issue with these.

All LED fixtures are on page 2 for convenience. I select all by holding first channel button and pressing the last and then I can see RGBW on the inbuilt screen - moved these to 0, press 'Record', 'Home', 'Default'. 

Only it doesn't seem to work. Still getting the flash - but only sometimes not every fade which baffles me. Do I need to set default fixture by fixture...?

Is there a way to look at the config of a fixture and see what the defaults are? At present  I seems I can only overwrite the default - without seeing its present state.

Any assistance would be gratefully received!

Cheers

Ian
