Troubleshooting Brake Controller that Shows No Lights on Display

Sounds like the controller has lost power or ground possibly which is why it's not showing any lights on the display. If the controller is hardwired to your vehicle check the condition of the connections on the white and black wires. If the power and ground connections are good then the issue would be an internal problem on the controller which would require replacing the controller.

The brake controller I recommend as a replacement is the Prodigy P3 part # 90195 because this brake controller senses the amount of braking your tow vehicle is applying and puts a proportional amount of braking on the trailer's brakes. It also has a display that uses full words instead of codes that would have to be deciphered. It's our best selling brake controller because of how well it works, how reliable it is, and how easy it is to use.
