LED Generic Wash Fixtures - issues when shutting down system and turning back on

I patched in 10 LED Generic 4 channel wash fixtures. I'm using a receiver and transmitter (one receiver for every 5 fixtures) and plugging into another universe. 

Everything was working great for the wash lights on the first day I patched everything in. Then I turned off the board and turned it back on today and now the lights aren't communicating with the board. 

Any ideas on what could potentially be the issue? Is there a specific order to turn everything on? Or something else that could be happening? 

Thanks!
