A failing LNB
The most common DStv fault by a wide margin. It sits on the dish arm, exposed to everything, and it degrades. Cheap to replace.

DStv repairs Randburg
No signal in Randburg? Pixelating channels, an error code on the screen, or a picture that dies the moment it rains? The fault is almost always outdoors — and it is almost always cheap.
The most common Randburg DStv fault we find is not dramatic at all: it is a connector at the LNB that was never properly weatherproofed, has slowly filled with water over several seasons, and has corroded to the point where signal quality has collapsed.
It presents as gradual decline. Channels disappearing one at a time. Breaking up in rain that never used to bother it. People live with it for months before they call anyone, and it is one of the cheapest things we fix.
So we test the whole chain in Randburg — signal at the LNB, signal at the wall point, cable integrity, connector condition and dish alignment — before anybody looks at the box under your television. It finds the fault faster and it is considerably cheaper for you.

What we find
In rough order of how often they turn out to be the cause.
01
The most common DStv fault by a wide margin. It sits on the dish arm, exposed to everything, and it degrades. Cheap to replace.
02
The connector at the dish end is outdoors permanently. Unsealed, it fills with water and the copper corrodes.
03
Wind, hail, a ladder, or a bracket that has slowly worked loose. Two degrees is all it takes.
04
The classic Randburg fault. Water in an unsealed LNB connector, degrading quietly over several seasons.
05
Highveld sun cracks the sheath, water gets in, and signal quality collapses. Rodents like coax too.
06
They do happen — power supplies, Explora hard drives, software. But they are a long way down this list, and we prove the signal chain first.
Error codes
DStv error codes are genuinely informative, if you know how to read them.
E48-32No usable signal from the dish. Signal-path fault, not a decoder fault
E16Often a subscription or smartcard issue — sometimes a signal too weak to decode
E30Partial signal loss. Some channels work, others do not. Classic degrading LNB
Pixelation and blockingSignal quality too low to reconstruct the picture cleanly
Rain fadeNormal in a downpour. In light rain, your installation has no margin left
Channels vanishing one by oneThe weakest transponders fail first. Your LNB is fading
Our process
01
Write down exactly what the screen says. It narrows things down enormously before we arrive.
02
Signal strength and signal quality — two different readings, two different meanings.
03
LNB, connector, cable, alignment or decoder. In that order, because that is the order of likelihood.
04
Including the weak transponders that fail first. Then we tell you how to stop it happening again.
FAQ
What people in Randburg ask us most often.
WhatsApp us the error code on the screen and a photo of your dish. We can usually narrow a DStv fault down before a technician is even dispatched.
WhatsApp 063 866 0971Yes. We repair DStv installations across Randburg and the surrounding suburbs — Ferndale, Cresta, Northcliff, Blairgowrie and nearby. Dish, LNB, cabling, connectors, decoder faults and signal problems.
Almost certainly not. ‘No signal’ means the decoder is working perfectly and receiving nothing from the dish. The fault is outdoors — the LNB, a corroded connector, damaged cable, or a dish knocked out of alignment. We test the chain from the dish inwards.
It means the decoder is not receiving a usable signal from the dish. It is a signal-path error, not a decoder fault, and it points at the LNB, the connectors, the cable or the alignment.
Rain fade — heavy rain absorbing the satellite signal. Every installation suffers it in a real Highveld downpour. But if yours breaks up in light rain, the installation has no margin left, usually because the alignment is marginal or the LNB is degrading. Both are inexpensive to fix.
The classic Randburg fault. Water in an unsealed LNB connector, degrading quietly over several seasons. It is one of the first things we check on a Randburg callout.
It depends what we find, but the good news is that the most common causes — a failed LNB, a corroded connector, a dish out of alignment — are all among the cheaper jobs we do. We quote a fixed price after the diagnosis.
Often, yes — particularly if you phone in the morning and you are in Randburg or nearby. We will give you an honest answer about timing rather than promising a slot we cannot keep.
