Applies to: TracVision TV3 with TV-Hub, revision C documentation. Confirm the installed receiver and switching hardware.
Match your symptom
| What you see | What to do next |
|---|---|
| One receiver works | If one onboard receiver works but another lacks channels, compare the same subscribed channel on both. Read TV-Hub’s selected satellite and switching mode before changing cables or the dish. A shared antenna follows a selected satellite; receivers and channel subscriptions still need compatible configuration. |
| Every receiver fails | On the TV-Hub Home page, note the selected satellite, antenna state and Automatic or Manual switching mode. In Automatic mode, also note the master receiver. If the antenna is tracking and one receiver works, investigate the affected receiver and switching configuration first. If all receivers fail while the antenna searches, investigate blockage or footprint coverage instead. |
Work through these checks
Confirm TV3 and TV-Hub
Check the label and the installed TV-Hub. Write down each receiver model and whether only one TV, one satellite’s channels, or every receiver is affected. Compare the TV input with the receiver’s menu: a missing menu is a different problem from an unavailable satellite channel. Photograph the current configuration before making permitted changes.
What the result means: If one onboard receiver works but another lacks channels, compare the same subscribed channel on both. Read TV-Hub’s selected satellite and switching mode before changing cables or the dish. A shared antenna follows a selected satellite; receivers and channel subscriptions still need compatible configuration.
Read the selected satellite
On the TV-Hub Home page, note the selected satellite, antenna state and Automatic or Manual switching mode. In Automatic mode, also note the master receiver. If the antenna is tracking and one receiver works, investigate the affected receiver and switching configuration first. If all receivers fail while the antenna searches, investigate blockage or footprint coverage instead.
What the result means: A master receiver’s channel selection can change the satellite being tracked. Check which receiver currently controls switching and compare whether the missing channel belongs to another satellite. Use the installed system’s documented receiver and switching settings; do not create a new satellite group or change LNB skew just to experiment. Ask the installer if the intended combination requires different switching hardware.
Check the master receiver
A master receiver’s channel selection can change the satellite being tracked. Check which receiver currently controls switching and compare whether the missing channel belongs to another satellite. Use the installed system’s documented receiver and switching settings; do not create a new satellite group or change LNB skew just to experiment. Ask the installer if the intended combination requires different switching hardware.
What the result means: If the desired satellite is already tracked, compare the affected receiver’s service authorization and satellite settings with its own manual. Test a known subscribed channel. Keep subscription faults separate from antenna faults. Do not move powered RF1 wiring between ports to copy a working receiver; preserve the installation and give the technician your comparison results.
Separate authorization from reception
If the desired satellite is already tracked, compare the affected receiver’s service authorization and satellite settings with its own manual. Test a known subscribed channel. Keep subscription faults separate from antenna faults. Do not move powered RF1 wiring between ports to copy a working receiver; preserve the installation and give the technician your comparison results.
What the result means: Stop for red fault indications, repeated power errors, damaged wiring or any work inside the dome. Contact KVH or a qualified marine installer. Three alternating orange TV-Hub lights indicate an update: do not interrupt power; the manual allows up to 40 minutes. Do not change emergency communications equipment to fix entertainment TV.
When to stop and get help
Stop for red fault indications, repeated power errors, damaged wiring or any work inside the dome. Contact KVH or a qualified marine installer. Three alternating orange TV-Hub lights indicate an update: do not interrupt power; the manual allows up to 40 minutes. Do not change emergency communications equipment to fix entertainment TV.
What to tell support
Record receiver models, affected channels, selected satellite, master receiver, switching mode and exact TV-Hub fault.
Common questions
Does Tracking guarantee every channel?
If one onboard receiver works but another lacks channels, compare the same subscribed channel on both. Read TV-Hub’s selected satellite and switching mode before changing cables or the dish. A shared antenna follows a selected satellite; receivers and channel subscriptions still need compatible configuration.
Can I power-cycle during orange lights?
Stop for red fault indications, repeated power errors, damaged wiring or any work inside the dome. Contact KVH or a qualified marine installer. Three alternating orange TV-Hub lights indicate an update: do not interrupt power; the manual allows up to 40 minutes. Do not change emergency communications equipment to fix entertainment TV.
