Encountering the DirecTV 775 or Cannot Detect SWM error can disrupt your entertainment experience. This guide will walk you through troubleshooting steps to diagnose and resolve this issue, ensuring you can get back to enjoying your favorite programs.

Understanding the Error

The DirecTV 775 or Cannot Detect SWM error indicates that your receiver is unable to establish communication with the Low-Noise Block downconverter (LNB) on your Trav'ler Pro antenna. This disruption in communication prevents the receiver from accessing satellite signals, resulting in a loss of TV service.

Troubleshooting Steps

1. Initiate a Search:
   

1. Even if your antenna appears to be locked onto a signal, initiate a search through the interface box. This action helps rule out potential issues with the LNB or sheath cable.
   
2. If the antenna does not lock on signal see our article on troubleshooting that issue. Troubleshooting: Winegard Trav'ler Pro No Signal Lock
   
3. If the error persists after the antenna successfully locks onto a signal, proceed to the next step.
   

1. Check the Power Inserter:

   • Locate the SWM power inserter.
   • Unplug it from the power outlet and then plug it back in.
   • Observe if the light on the power inserter illuminates.
   • If the light remains off:
     • Disconnect the coax cable from the "PWR to SWM" port on the power inserter.
     • Unplug the power inserter and plug it back in.
     • Check if the light illuminates now.
     • If the light still doesn't turn on, the power inserter likely needs replacement.

2. Check the Splitter:

   • If the power inserter's light is on, verify if the splitter is positioned between the power inserter and the antenna in the coax line.
   • If it is, remove the splitter from the coax line.
   • Check if the error message disappears.
   • If removing the splitter doesn't resolve the issue, proceed to the next step.

3. Run an External Coax Cable:

   • Run a separate coax cable directly from the 'C' port at the base of the Trav'ler antenna to the "PWR to SWM" port on the power inserter.
   • Observe if the error message is cleared.
   • If the error persists, move on to the next step.

4. Bypass the Turret:

   • Power off the interface box.
   • Disconnect the cable connected to the 'C' port at the base and the red sheath cable connected to the bottom port on the turret.
   • Use a coax coupler/barrel connector to join these two cables together.
   • Check if the error is resolved.
   • If the error remains, continue to the next step.

5. Test the Power Inserter:

   • Reconnect the splitter.
   • Connect the antenna to the splitter, then connect the splitter to the power inserter.
   • Connect the receiver to an available port on the splitter (not the power inserter).
   • Check if the error message is cleared.
   • If the error continues, proceed to the next step.

6. Contact DirecTV:

   • If none of the previous steps resolve the issue, the problem might lie with the receiver itself.
   • Reach out to DirecTV to explore the possibility of obtaining a replacement receiver.
