1. Reset the power to the sign. This can be done by turning off the breaker, waiting 15 seconds, and then turning on the breaker.  If this corrects the problem, continue to monitor the sign for the next couple of days to make sure it is not a reoccuring issue.

2. If after the power reset the sign stays blank, use the Ping Program on your CD to try to communicate with the sign. If you do not have this program or lost your CD, you can call Datatronic Control, Inc directly and we can email you over the program. The program will inform you if a certian component cannot establish a ping. If the ping to the sign computer fails, you will need to physically check the sign computer. It is possible that the Reciever Card’s Power Supply on the Master face has failed.
