The "NO LNB VOLTAGE" error on a Winegard Trav'ler antenna typically indicates a problem with the cable that connects the LNB (Low Noise Block converter) to the antenna's turret. The troubleshooting steps vary slightly depending on the specific Trav'ler model you have.

Troubleshooting Steps

1. Identify the Trav'ler Model: The first step is to identify the specific Trav'ler model you have, as this will dictate the exact troubleshooting steps.

2. DirecTV SWM3 Model:

   • Troubleshooting:
     • Replace the existing cable with a standard RG6 coax cable.
     • If the error persists, the problem lies within the turret, requiring repair or replacement. Submit a support ticket for assistance.

3. DISH 1000 Model:

   • Troubleshooting:
     • Swap the cable connections on the vertical A and C ports. If you have a 2-cable set, you'll also need to swap cables at the LNB.
     • If the error disappears, the original cable is faulty and needs replacement.
     • If the error remains, and you have a 3-cable set, try the third cable on the C port to see if the error clears.
       
     • If the error persists, the turret is likely the issue and will need repair or replacement. Submit a support ticket for assistance
       

4. Shaw Model:

   • Troubleshooting:
     • Swap the cable connections on the vertical A and C ports.
     • If the error persists, try each cable on the C port individually to see if the error clears.
     • If the error is resolved by swapping cables, the original cable is faulty and needs replacement.
     • If the error remains, the turret likely needs repair or replacement. Submit a support ticket for assistance.

Important Notes:

• If your system is under warranty, submit a support ticket for assistance with repairs or replacements.
• If your system is out of warranty, you may need to purchase replacement parts.
• If you are uncomfortable performing these steps yourself, you can seek assistance from a qualified technician or RV dealer.

Remember to prioritize safety when working on your Trav'ler antenna, especially when accessing the roof of your vehicle. If you have any doubts or concerns, it's always best to consult a professional.
