RED X error 3

Glad to help you troubleshoot this error message, drparpart.

Since restarting the receiver didn't solve the problem, unplug your Wi-Fi gateway and wait two minutes, then plug it back in and restart. This will temporarily disrupt internet, TV, and Voice service.

If the error message still won't go away, use the Troubleshoot & Resolve Tool for U-verse TV to run diagnostics and find out what's causing this.

1. Press Menu on the U-verse Remote Control.   
2. Scroll down to Help, then press OK.   
3. Select Information.
4. Scroll to Troubleshoot & Resolve, then press OK.   
5. Select the service you want to troubleshoot and allow the interactive diagnostic test to run and complete.   
6. Follow the onscreen instructions to resolve. Other options may include dispatching a technician or speaking to a Customer Care agent.

If you need further assistance, let us know.
