Every fault below comes from real call-outs across Durban and surrounding areas. Some have a quick check you can try yourself before booking anyone — where that's true, we say so. When a visit is needed, the diagnosis is done with a signal meter, quoted before work starts, and covered by our 12-month workmanship warranty. New to this part? Start with the lnb (low-noise block) component guide.
1. Faulty LNB — no signal on any channelE48-32, E30
What you'll see: Total loss of signal across every channel, with the dish visibly still pointing where it always did and no storm or knock to explain it.
Why it happens: The LNB has failed. It is the only powered component outdoors, exposed to sun, rain and surges year-round, and it is the most common single hardware failure in a satellite installation.
How we fix it: We confirm the LNB is dead by measuring at the cable and, where necessary, substituting a known-good unit, then fit the correct replacement type for your setup and re-seal the connection properly so the same failure does not repeat.

2. Water in the LNB after rainE48-32 (intermittent)
What you'll see: Reception fails during or after rain and returns a day or two later once things dry out. Each cycle it takes longer to come back, until eventually it does not.
Why it happens: Water is entering the LNB housing or the F-connector, usually through a perished weatherproof boot, an unsealed connector, or a cable dressed so that water runs down it into the connection instead of away from it.
How we fix it: We replace the LNB and the affected connector, compression-fit and seal the new one, and dress the cable with a proper drip loop so water is directed away from the entry point. Sealing the cause is what stops this recurring.
3. Extra View needs a Smart LNBE48-32 on the second decoder
What you'll see: Your main decoder works perfectly but a newly added second decoder will not get signal, or the two decoders interfere with each other so that changing channels in one room affects the other.
Why it happens: The existing LNB has too few independent outputs for the number of decoders, or the setup needs a Smart LNB to run multiple decoders down a single cable and the older universal LNB cannot do it.
How we fix it: We assess whether your existing cabling supports the setup you want, then fit a Smart LNB or an appropriate multi-output LNB — usually avoiding a second cable run through the roof entirely.
4. Corroded LNB connectorE48-32 (intermittent)
What you'll see: Signal quality has been slowly deteriorating for months, with increasing pixelation, and the F-connector at the LNB looks green, white-crusted or rusty when inspected.
Why it happens: Galvanic corrosion at the connector, accelerated near the coast by salt air and anywhere by moisture that has been getting in past a failed seal.
How we fix it: We cut back the cable to clean, bright copper, fit a new compression F-connector, seal it properly, and — on coastal installations — specify corrosion-resistant hardware so the repair actually lasts.
Symptom doesn't match any of these?
