Why Is My Extra View Decoder Showing an Error When the Main Decoder Works?

By the Remtech Installers team · Updated October 2026 · 4 min read

The short answer

Usually the second decoder has lost its link to the main one, has a fault on its own cable run, or is showing a subscription code (E16 or E30) that needs clearing. Power-cycle both decoders, check the connectors and give them a few minutes. If the error returns, an accredited installer should check the link and the cable.

How Extra View works in plain English

Extra View lets more than one decoder run on a single DStv account. One decoder is the primary and the others are secondary. Each decoder needs its own signal path from the LNB, and the secondary ones also depend on their link to the primary.

That is why one decoder can work perfectly while another shows an error. They share an account, but they don’t share every point of failure.

What the error is telling you

What you seeUsually meansWhat to try
E48-32A signal problem on that decoder’s pathCheck its connectors and cable run, then the dish if every decoder fails
E16A subscription or authorisation messageTry DStv’s self-service options, and give the decoder a few minutes after payment
E30The decoder is confirming your serviceWait a few minutes without pressing buttons, then clear it through self-service if it stays
Secondary only shows an access errorThe secondary may have lost its link or authorisationPower-cycle both, then ask an installer to check the link

Code behaviour can differ between models, so confirm the current steps with DStv.

Five-minute checks

  1. Power-cycle both decoders. Switch them off at the wall for about 30 seconds, then switch them on.
  2. Check each smartcard is fully seated.
  3. Check the coax connectors at the decoder and wall point. They should be firm and undamaged.
  4. Check the cable is in the right input. The cable from the LNB should go to the LNB input, not an RF output.
  5. Wait five to ten minutes after start-up. Authorisation can take a few minutes to reach every decoder.

Is it the secondary only, or everything?

  • Only the secondary fails: look at its own cable run, its connectors, and its link or authorisation.
  • Every decoder fails together: the fault is at the dish, the LNB or the main cable. Read our E48-32 guide.
  • Only the primary fails: check its subscription messages and signal path.

Second decoder still not working?

Send us the decoder models and what the screen says. We will tell you the likely cause and quote you for free.

Older Extra View setups used a heartbeat cable and a diplexer to link decoders. Installer guides report that newer Smart LNB setups may not need a physical heartbeat cable. Because the details depend on your decoder models, we check the exact setup on site rather than guess.

Linking and activating a decoder on your account is done through DStv, usually by an accredited installer. If you swapped a decoder or moved house, the link may need to be re-registered.

Storms, surges and load shedding

Power returning after load shedding can trip or confuse decoders, and storms can damage equipment. A surge protector on each decoder, and a full power-cycle after a long outage, solves more problems than people expect.

What to tell your installer

  • The models of the primary and secondary decoders.
  • Serial numbers (photograph the labels).
  • When it started, and whether a move, storm or power cut came first.
  • What you have already tried.

We cover Extra View installations across Gauteng, including Sandton, Midrand and Pretoria East. Most Extra View setups also depend on the right LNB, so see our Smart LNB and Explora page.

Frequently asked questions

DStv charges a separate monthly fee for an extra decoder on your account. Check the current amount with DStv.

It can take a few minutes for authorisation to reach every decoder. If it persists, try DStv’s self-service options or call DStv, and ask your installer to check the link.

Not just by carrying it. It needs a cable run from the LNB to the new room and a signal check. See our Extra View installations.

Only if the LNB is the cause. DStv recommends the Smart LNB for most Extra View installations in single dwellings, but it won’t fix a bad connector or an unlinked decoder.
