One of my F16V3 Controllers has a Differential Expansion Board. One string-port of one of the Differential Receivers is telling the string to stay on solid white all the time even when no signal is provided. It never turns off. When a real signal is sent to the port you can vaguely see it modulating the white but it is still all white. I swapped things around and confirmed it is definitely a ?white signal? coming from the port. The Receiver has worked fine for two years until now. When I powered down the Falcon Controller and the Differential Expansion board the LED string connected to that Receiver port stayed on solid white. Any suggestions as to a fix or further troubleshooting?

It sounds like a stuck string. If you cut power to the string and reconnect it does it work for a while and then get stuck again ... this can happen when a string when all white draws so much current the string becomes unable to read the data signal and thus doesnt see any new instructions. The fix is power injection or a thicker ground wire.

I had tried powering down the receiver box completely but when I plugged it back in the port came back on solid white. At that point I just unplugged that port. Today I plugged the port back in and it is working properly again. Hopefully it continues working. Thanks.
