I have an Express 48/96 that is outputting some odd data. It will essentially flash dimmers channels on and off at somewhat random intervals. Originally it was used to output directly to a Sensor Classic and we never noticed this, but in recent years we replaced the Express as the primary controller with LightFactory and began using the Express as an input wing of sorts using an ENTTEC dongle.
The problem is that when connected to LightFactory it will trigger random submasters on and off (LightFactory recognizes the DMX output as submaster input- which makes for a nice physical fader wing). I've replaced the optocoupler and communications chips on both port 1 and 2, but no change in the output was noticed.
Are there any other smoking guns with this console? The issue crops up the same in both outputs, so it isn't confined to that part. I thought the optocoupler might be the culprit, but no dice. I'm not sure I want to invest in sending the board in for repairs when I could just buy a cheapy DMX controller to use as a wing, but I'd like to fix the Express if possible since it is a good controller.
Here is a video of the issue-

For the video, I've got the board output going into a DMX Pro and then into a laptop running LightFactory displaying the DMX input window.
