Many owners of older Humax Freesat set top boxes may suddenly discover that BBC HD channels have disappeared or started displaying “No Signal” messages despite other channels continuing to work normally.

The issue has affected a large number of Humax Freesat boxes following changes to BBC HD broadcasting parameters on the Astra satellites at 28.2° East. In most cases, the problem is not caused by dish alignment, bad weather or faulty cabling, but instead by outdated tuning information stored inside older Humax receivers.

Viewers affected by the issue may notice problems with channels such as:

• BBC One HD
• BBC Two HD
• BBC News HD
• CBBC HD
• BBC Scotland HD

Standard definition BBC channels may continue working correctly while only HD services fail.

The problem particularly affects older Humax Freesat models including:

• Humax HDR Foxsat
• Humax Foxsat HD
• Early Freesat HD receivers

These receivers rely on stored transponder information to locate satellite channels. When broadcasters move services to new frequencies or alter transmission settings, older boxes can sometimes fail to update automatically.

In this case, the BBC moved several HD services onto different satellite transponders as part of wider Astra satellite capacity changes and broadcasting upgrades.

As a result, many older Humax receivers will still attempt to search for BBC HD channels using outdated tuning parameters, leading to “No Signal” errors even though the channels remain fully operational.

Fortunately, the issue can usually be resolved without replacing the receiver.

The Main Fix for BBC HD No Signal Errors

For most Humax Freesat users, the solution involves forcing the receiver to reload updated channel information.

Why This Issue Happened

Satellite broadcasters regularly reorganise transponders and frequencies as part of capacity management and service upgrades.

The BBC HD changes formed part of wider adjustments on Astra satellites used for UK television broadcasting.

Newer Freesat receivers generally updated automatically without users noticing any changes, but older Humax boxes have historically been more sensitive to certain transponder updates.

Because these older receivers are now many years old, software support and automatic update systems may no longer work as reliably as they once did.

Do You Need a New Receiver?

In most cases, no.

Many Humax Freesat receivers will continue working perfectly once updated channel data has been reloaded.

However, some very old receivers may occasionally experience further issues as broadcasters continue modernising satellite transmission systems.

Newer Freesat boxes support:

• Improved HD compatibility
• Better channel updates
• DVB-S2 efficiency improvements
• Faster programme guides
• Streaming services and catch-up TV

For viewers still using early Freesat HD hardware, this issue may eventually encourage an upgrade to newer equipment.

A Common Problem for Older Satellite Equipment

This BBC HD issue highlights one of the ongoing challenges with long-running satellite TV systems.

Unlike internet streaming devices that update constantly in the background, older satellite receivers sometimes rely on manual resets and retuning when broadcasters make technical changes behind the scenes.

Fortunately, in most cases, the Humax BBC HD “No Signal” issue can be fixed relatively quickly without any changes to the dish or cabling.

For many viewers, a simple reset and fresh Freesat installation will be enough to restore all missing BBC HD channels.
