Topic: UFX Screen Malfunction
NB: I searched and couldn't find a comprehensive answer/solution in any thread.
I have been dealing with built-in screen reliability issues with my Fireface UFX (serial 23429444, latest firmware v357 and latest USB driver v3.01) since purchase in late August 2012. At first, it would randomly flash to blank white at startup and thereafter until rebooting the unit, which would generally fix the problem until shutting down the unit. Later, this fix became temporary such that after rebooting the unit, the screen would stay error free for a while (anywhere from ~10 minutes to several hours) but would eventually start flashing to blank white. This was its behavior until just recently when I replaced my late 2011 MacBook Pro running Mac OS 10.10.5 with a late 2015 iMac running 10.12.4. Now, it starts flashing to white almost immediately upon startup and a reboot does not fix the problem.
The unit is plugged directly into one of the USB 3.0 ports on the back of the iMac, not through a hub or to a port on a Thunderbolt expansion chassis. I have updated to the latest USB driver for macOS Sierra. I have reflashed the latest firmware. None of this has done anything to fix or improve the issues with the screen. All other functions seem to work just fine, whether accessed through the hardware or through TotalMix, though admittedly I have not tested absolutely everything.
What should I do?
