The remote stopped working overnight? IR sensor not responding? Voice remote refusing to pair? We fix every kind of remote-control fault — from a R300 button repair to full Samsung One Remote and LG Magic Remote diagnostics.
Send TV brand and what the remote is doing — we come back with a likely cause and price.
A working television remote is one of those small bits of household technology that you don't think about until it suddenly stops working — and then the entire TV becomes maddeningly difficult to use. The frustration is real, especially on modern Smart TVs where the touchpad and voice features of remotes like the Samsung One Remote and the LG Magic Remote are now essential to navigating Tizen and webOS menus.
The good news is that remote and sensor faults are among the cheapest and quickest repairs in our entire workshop. Most are resolved for under R1,100, the majority complete same-day, and a meaningful percentage — perhaps one in four — turn out to be simple battery, pairing or button-cleaning issues that don't need hardware replacement at all. Our remote bench is set up to triage every kind of fault quickly and tell you straight whether you need a R300 button repair, a R780 IR receiver replacement, or just a fresh set of batteries.
Five small components, working together, every time you press a button.
A conductive rubber dome closes a circuit on the remote's PCB.
A tiny chip translates the press into an IR or Bluetooth data packet.
An IR LED flashes at ~38kHz or a Bluetooth radio sends to the TV.
IR sensor or BT radio on the TV captures the data packet.
The IR control IC decodes the packet and triggers the action.
A fault at any of those five points means the TV doesn't respond. Identifying which one matters — because each fault has a completely different fix and a different price.
Most remote-and-sensor faults fall neatly into one of these tiers.
IR receiver module desolder and replace. Most common faulty-IR repair, completed in under an hour.
IR sensor + main-board IR control IC replacement when both stages have failed (lightning damage cases).
Bluetooth remote pairing service for Samsung One Remote, LG Magic Remote, Hisense Voice and TCL Voice.
Please note that all prices displayed are estimated starting prices only. Final repair costs may vary depending on the TV size, model, fault diagnosis, parts required, labour, and any additional repairs needed after inspection. Replacement universal remotes from R300–R600.
Spilled liquid, dust ingress or worn rubber contacts. Clean, recoat or full rubber pad replacement from R300.
Often a flat battery or failed IR sensor. Phone-camera test: point remote at phone camera and press — you should see the IR LED flash on screen.
Microphone failure, lost pairing or firmware fault. Pairing reset R550, replacement voice remote R780–R1,450.
Almost always a failed IR LED on the remote or a failed IR receiver on the TV. We test both stages and identify which side has failed.
Samsung One Remote and LG Magic Remote occasionally lose pairing after firmware updates. Service-mode re-pair R550.
Has to be very close to the TV to work? Usually a weakening IR LED on the remote — sometimes the IR sensor on the TV is partly obscured by build-up.
Original remote lost or beyond repair. Brand-compatible universal remotes from R300 with full setup included.
SmartThings, LG ThinQ or VIDAA app not controlling the TV. Usually a Wi-Fi or pairing issue we fix in-home.
Remote Specialists
Remote and sensor issues are some of the most rewarding repairs we do — they're the kind of small, fast fix that can transform an unusable TV back into a working one in under an hour, for under R1,100. We don't push customers toward replacing the whole TV for a R780 IR sensor problem, and we don't quote main-board replacements when a pairing reset will solve everything.
Our remote bench stocks OEM IR receiver modules for every major brand sold in South Africa, replacement universal remotes from R300 (with full pre-programming for your TV), brand-matched replacement voice remotes for Samsung One Remote, LG Magic Remote, Hisense VIDAA Voice and TCL Voice, plus the service-mode tools to reset pairing lists on Tizen, webOS, VIDAA and Google TV. Most repairs are completed in a single visit.
Every remote and sensor repair carries our 90-day workmanship and parts warranty. Universal replacement remotes carry the manufacturer's 6 or 12-month warranty. If we can't fix the fault, you don't pay for the diagnostic time.
In-home remote repair available across the major centres — often same day.

A TV that won't respond to the remote almost always has one of four faults: dead or weak batteries (always test these first — they're the cheapest fix), a failed IR receiver on the TV's front panel, a failed IR control IC on the main board, or — on modern Bluetooth/voice remotes — a lost pairing after a firmware update. We diagnose all four for between R300 and R1,550. Phone-camera tip: point your remote at your phone camera and press a button — you should see the IR LED flash on the camera screen. If you see it, the remote is OK and the fault is on the TV.
Yes — the IR receiver module is a discrete component on the front of the TV, usually mounted on a small sub-board behind the bezel or the bottom edge of the screen. It desolders and replaces in under an hour. Total cost in Gauteng is R550–R1,050 including the OEM-grade IR module. It's one of the cheapest and quickest TV repairs we do.
Most Bluetooth remotes pair by holding two specific buttons together for 5–10 seconds with fresh batteries fitted and the TV powered on. Samsung One Remote typically uses Return + Play; LG Magic Remote uses the wheel button + Back; Hisense VIDAA Voice remotes vary by model; TCL Bluetooth remotes use Home + Volume Down on most generations. When the pairing handshake fails repeatedly, the remote's Bluetooth module may have failed or the TV's pairing list needs clearing via service mode (R550).
Voice remotes — Samsung Bixby, LG ThinQ, Hisense VIDAA Voice, Google Assistant on Sony/TCL — depend on both active Bluetooth connectivity and a working microphone in the remote itself. Voice failures are most commonly firmware-related (resolved by a R550 service-mode pairing reset that re-registers the voice service), or a damaged microphone capsule in the remote itself (replacement voice remote: R780–R1,450 depending on brand).
Yes. Stuck or unresponsive buttons on a TV remote are almost always caused by one of three things: spilled liquid (the most common culprit), dust ingress under the rubber dome contacts, or worn conductive coating on the rubber pad. We open the remote, clean the PCB contacts and rubber pad, recoat or replace the conductive surface, and reassemble. Cost from R300.
IR receiver replacement on the TV side typically costs R550–R1,050 including the OEM-grade IR module and labour. If the fault is upstream of the receiver — at the main-board IR control IC level — repair is R900–R1,550. We always diagnose which stage has failed before quoting, so you never pay for a fix you don't need.
For any IR-controlled TV — which covers the vast majority of sets sold in South Africa — yes. A quality universal remote works with any IR TV from R300 upwards. The exception is Bluetooth-only voice remotes on the latest Samsung Frame, Samsung S95-series and LG OLED models, which require either the original remote or a paired smartphone app (SmartThings or LG ThinQ). We supply and program the right type for your TV.
Yes — every remote, IR receiver and sensor repair carries our standard 90-day workmanship and parts warranty. Universal replacement remotes that we supply carry the manufacturer's standard 6 or 12-month warranty. Our no-fix-no-fee policy also applies to the diagnostic time.
It's one of the more frustrating mid-evening household discoveries: the TV remote suddenly stops working. The buttons feel fine, the batteries were changed not long ago, but nothing the remote sends is reaching the television. Or, equally common in the modern Smart TV era — the Bluetooth voice remote that worked yesterday won't pair today, the on-screen cursor on the LG Magic Remote refuses to appear, or the Samsung One Remote's "Hey Bixby" voice button does nothing. The frustration is real because the TV is otherwise perfectly functional; it's just become almost impossible to drive.
At Nathtec TV Repairs we've spent more than a decade resolving exactly these faults for households across Gauteng. Remote and sensor complaints account for around one in eight of the repair tickets that pass through our Johannesburg workshop in any given month — and they're some of the most satisfying fixes we do, because almost every single one is resolvable for under R1,100, most are completed same-day, and a meaningful percentage (probably one in four) turn out to be simple battery or pairing issues that need no real "repair" at all. The trick is having the right diagnostic process and the right OEM parts on hand.
Almost every TV remote sold in South Africa falls into one of two technology categories, and the failure modes are completely different for each. Infrared (IR) remotes use a small LED on the front of the remote that flashes invisible infrared light at around 38kHz, encoding the button press as a series of timed pulses that the TV's IR receiver decodes. They are the older technology but still by far the most common — every entry-level Samsung, LG, Hisense, TCL, Skyworth and Panasonic TV ships with an IR remote. They are line-of-sight only (the remote has to point roughly at the TV) and have an effective range of about 8 metres.
Bluetooth remotes use the same Bluetooth radio that the TV uses for Bluetooth headphones and soundbars. They don't require line-of-sight, they work through furniture, and they support voice input via the microphone in the remote itself. Samsung's One Remote, LG's Magic Remote (with its point-and-click cursor), Hisense's VIDAA Voice remote and TCL's Voice remote are all Bluetooth-based. They pair to the TV the first time they're powered on (or after a service-mode reset), and they remain paired until the pairing list is cleared. They fail in completely different ways from IR remotes.
Before anything else: replace the batteries. This sounds painfully obvious but it's the single most common "fault" we see, particularly with the energy-efficient remotes on modern Smart TVs which can sit on standby for months drawing tiny amounts of current from the cells. Use fresh, name-brand alkaline cells from a reputable seller — and use a matched pair. Mixed old-and-new cells, or two cells from different brands, are a frequent cause of intermittent remote behaviour.
If fresh batteries don't fix it, do the phone-camera test. Point the remote at the rear-facing camera of your smartphone, look at the camera preview on the phone screen, and press any button on the remote. Almost every modern phone camera can see infrared light, so you should see the IR LED on the front of the remote flashing brightly on screen. If you see the flash, the remote is working correctly and the fault is on the TV (most likely the IR receiver). If you see no flash, the remote itself has failed — usually the IR LED, sometimes a battery contact, sometimes a stuck button shorting the circuit. For Bluetooth remotes the camera test doesn't apply; instead, check whether the TV's Bluetooth settings menu shows the remote as paired and connected.
If the camera test shows the remote is transmitting fine but the TV doesn't respond, the fault is almost certainly the IR receiver module on the TV. This is a small discrete component — typically a black plastic encapsulated photodiode with three or four leads — mounted on a small sub-board behind the TV's front bezel or bottom edge. It can fail from age (uncommon), from electrical damage following a power surge or lightning event (the most common cause in South African conditions), or from physical damage if the front bezel has been knocked.
The repair is satisfyingly straightforward. We remove the TV's rear cover, access the IR sub-board, desolder the failed receiver module, fit an OEM-grade replacement, resolder and reassemble. Total time is under an hour for almost every TV. Total cost in our Gauteng workshop is R550–R1,050 including the part. In some cases the fault is one level deeper — on the main-board IR control IC that decodes the signal coming in from the receiver — in which case the repair extends to that IC and costs R900–R1,550. We always diagnose which stage has actually failed before quoting.
Bluetooth remotes introduce a different class of fault entirely. The most common Bluetooth-remote complaint we see is lost pairing — the remote suddenly stops working, fresh batteries don't help, and the TV's Bluetooth settings either don't show the remote at all or show it as "not connected". This usually happens after a Smart TV firmware update has reset some part of the Bluetooth stack, or after the TV has been factory-reset, or after weeks of standby with depleted batteries.
The fix is a service-mode pairing reset. Each brand has its own procedure: Samsung One Remote typically re-pairs by holding the Return and Play buttons together for 5–10 seconds in front of the TV; LG Magic Remote uses the scroll wheel + Back button held for several seconds with fresh batteries; Hisense VIDAA Voice remotes vary by model series; TCL Voice remotes typically use the Home + Volume Down combination. When the standard button-combo procedure fails to re-pair, we use the TV's service mode to clear the existing pairing list, force a fresh pairing handshake, and re-register the voice service for the microphone button. This service costs R550 and is usually completed in-home in under 30 minutes.
Voice remotes — those with a microphone for Bixby, Google Assistant, ThinQ or VIDAA Voice — add yet another failure layer on top of standard Bluetooth pairing. The microphone is a separate small electret or MEMS capsule inside the remote, and it can fail independently of the Bluetooth and IR functions. When the voice button does nothing while the rest of the remote works fine, the most likely cause is microphone failure rather than a pairing issue — and the most cost-effective fix is usually a brand-matched replacement voice remote rather than micro-soldering work on the original.
We stock or source brand-matched replacement voice remotes for the major models — Samsung One Remote (various generations), LG Magic Remote (MR21 / MR22 / MR23), Hisense VIDAA Voice and TCL Voice — typically for R780–R1,450 including pairing. We also supply quality universal remotes from R300 with full pre-programming for your specific TV, which is the right answer for many older or budget sets where the original remote has simply been lost or worn out beyond repair.
The last major category of remote fault is the one that affects every household with children, coffee or remotes that have been used heavily for many years. Stuck buttons, unresponsive presses on specific buttons, or the strange "ghost-press" behaviour where the volume keeps going up by itself are all classic symptoms of physical contamination or wear inside the remote. The rubber dome contacts on the underside of each button have a small conductive carbon coating that wears with use, and dust or sticky residue from spilled drinks can lodge between the rubber and the underlying PCB contacts.
Our remote-disassembly bench cleans every contact, replaces worn conductive coatings (using proper conductive ink rather than the foil-trick from internet tutorials), and replaces complete rubber pads when they're too far gone to recoat. Total cost from R300 for a standard remote clean-and-recoat, more for a full rubber-pad replacement on premium remotes. Most are completed same-day and the customer walks out with a remote that feels new again.
For the great majority of remote and sensor faults, same-day repair is genuinely achievable — IR receiver replacement, Bluetooth pairing reset, button cleaning and universal remote setup are all in-home or workshop repairs that complete within hours. We cover Johannesburg, Sandton, Pretoria, Midrand, Randburg and Soweto for in-home remote service.
