By Refitec Kenya | TV & Electronics Repair Experts
Does a surge protector protect your TV from damage? Yes. A surge protector absorbs voltage spikes before they reach your TV’s internal components, preventing costly circuit damage or total failure.
What causes TV damage from power surges in Kenya? The most common causes are sudden KPLC power restoration after outages, lightning strikes on power lines, load shedding cycles, and faulty wiring in older buildings.
How much does it cost to repair a TV damaged by a power surge in Kenya? TV power surge repairs at Refitec Kenya typically range from KES 2,500 to KES 18,000 depending on the extent of the damage — far more than the cost of a good surge protector.
Is a surge protector the same as a power strip? No. A basic power strip only adds extra sockets. A surge protector contains a Metal Oxide Varistor (MOV) that actively diverts excess voltage, keeping your TV safe.
What surge protector rating should I get for my TV? Look for a surge protector rated at least 1,000 joules or higher for televisions. The higher the joule rating, the more protection it provides.
The Full Picture: Why Your TV Needs a Surge Protector in Kenya
The Hidden Enemy: Power Surges
Your television is one of the most expensive and frequently used appliances in your home. Yet most Kenyan households leave their TVs completely exposed to one of the most damaging and invisible threats in the electrical environment — power surges.
A power surge is a sudden, brief spike in electrical voltage that travels through your power lines and directly into every appliance plugged into your sockets. These spikes can last as little as a few microseconds, but in that tiny window, they can permanently destroy the delicate circuit boards, capacitors, and power supply units inside your TV.
At Refitec Kenya, we repair TVs every week that have suffered surge-related damage — damage that was entirely preventable with one simple, affordable device.
Why Power Surges Are Especially Common in Kenya
Kenya’s power grid, while steadily improving, presents specific challenges that make surge protection a necessity rather than a luxury.
KPLC Power Restoration Spikes When Kenya Power restores electricity after an outage or load shedding, the sudden return of current often carries a voltage spike. Your TV, if left plugged in, receives that spike in full force. This is the single most common cause of surge-related TV damage we see at Refitec Kenya.
Frequent Load Shedding Cycles Repeated on-off power cycling creates cumulative wear on your TV’s power supply unit. Even if a single surge does not destroy your TV outright, repeated smaller surges degrade internal components over time, leading to early failure.
Lightning and Rainy Season Surges Kenya’s long and short rain seasons bring increased risk of lightning strikes on overhead power lines. A strike does not have to hit your building directly — a nearby strike on a transformer or line can send a devastating surge through the entire neighbourhood’s electrical supply simultaneously.
Ageing Wiring in Older Buildings Many residential and commercial buildings in Nairobi, Mombasa, Kisumu, and other towns still have older wiring that lacks proper earthing (grounding). Poor earthing means voltage spikes have nowhere safe to dissipate, so they travel straight into your appliances.
What a Power Surge Actually Does to Your TV
Understanding the internal damage helps explain why repair bills can be so high. Modern televisions — whether LED, OLED, Smart TVs, or QLED — contain highly sensitive electronic components that operate within precise voltage ranges.
When a surge occurs, the excess voltage first hits the TV’s power supply board. This board is responsible for converting the wall current into the various lower voltages that power the screen, processor, and other components. A strong surge can instantly burn out the capacitors and diodes on this board, causing the TV to go completely dead.
If the surge partially bypasses the power supply, it can reach the main board — the brain of your TV — damaging the processor or memory chips. It can also reach the T-Con board, which controls image processing, resulting in symptoms like a black screen, vertical lines, or a backlight that turns on but shows no picture.
In severe cases involving Smart TVs, the Wi-Fi module, USB ports, and HDMI input chips can all be fried, requiring either multiple board replacements or, in the worst scenarios, a full TV replacement.
How a Surge Protector Works: Step by Step
Step 1 — Normal Operation Under normal conditions, your mains voltage in Kenya should be approximately 240V AC. Your surge protector allows this normal voltage to pass through freely to your TV without any interference.
Step 2 — A Surge Is Detected When a voltage spike occurs — say the voltage jumps from 240V to 500V or higher in a fraction of a second — the surge protector’s internal Metal Oxide Varistor (MOV) detects the abnormal voltage.
Step 3 — Excess Voltage Is Diverted The MOV becomes conductive when voltage exceeds its threshold, instantly creating a low-resistance path that redirects the excess voltage away from your TV and channels it safely to the earth wire in your socket.
Step 4 — Normal Voltage Resumes Once the spike has passed and voltage returns to the normal 240V range, the MOV returns to its non-conductive state and power flows normally to your TV — all of this happening in nanoseconds, completely invisibly to you.
Step 5 — Protection Accumulates Over Time Each surge the MOV absorbs uses up a small portion of its joule capacity. This is why surge protectors have a joule rating — it represents the total cumulative energy the device can absorb over its lifetime. A 1,000-joule protector can absorb far more surges before its protection degrades compared to a 200-joule unit.
How to Choose the Right Surge Protector for Your TV
Not all surge protectors are equal, and buying the cheapest option at a supermarket may give you false confidence. Here is what to look for.
Joule Rating: For a standard LED or Smart TV, look for a minimum of 1,000 joules. For larger, high-end TVs such as 55-inch and above OLEDs or QLEDs, aim for 2,000 joules or more.
Response Time: Look for a response time of 1 nanosecond or less. The faster it reacts, the more of the surge it blocks before any voltage reaches your TV.
Clamping Voltage: This is the voltage level at which the surge protector activates. Look for a clamping voltage of 400V or below.
UL or CE Certification: Buy a surge protector that is UL-listed or carries a CE certification. Be wary of uncertified generic products that may have no genuine MOV inside.
Indicator Light: A good surge protector has an indicator light that confirms its protection is still active. If the light goes out, the MOV is exhausted and the device needs replacing.
Number of Sockets: Look for a unit with at least 4 to 6 sockets to accommodate your TV, decoder, gaming console, sound system, and router through one protected unit.
Proper Usage: Getting the Most Out of Your Surge Protector
Always plug your surge protector directly into a wall socket rather than daisy-chaining it through another power strip or extension cord. Daisy-chaining reduces effectiveness and can create fire hazards.
Make sure your wall socket is properly earthed. A surge protector can only divert excess voltage safely if there is a functioning earth wire in your socket. If your sockets lack earth connections, have a qualified electrician fix this first.
Unplug your TV and surge protector during prolonged outages or when a major storm is approaching. A surge protector handles typical grid surges well, but an extreme lightning strike close to your home can overwhelm even a high-quality protector.
Replace your surge protector every 2 to 3 years, or immediately after a major power event such as a direct lightning strike nearby.
Do not overload your surge protector by plugging in high-wattage appliances such as kettles, microwaves, or irons. These draw far more current than a surge protector is designed for.
The Cost Comparison: Surge Protector vs. TV Repair
A quality surge protector in Kenya retails for between KES 800 and KES 3,500. Compare that to what Refitec Kenya commonly sees for surge-related TV repairs: a blown power supply board replacement runs KES 3,500 to KES 7,000; a damaged main board replacement costs KES 5,000 to KES 12,000; and full multi-board repair on a high-end Smart TV can reach KES 15,000 to KES 18,000. In the worst cases, a full TV replacement runs KES 35,000 or more. One quality surge protector costs far less over five years than a single major repair job.
When to Bring Your TV to Refitec Kenya
If your TV has already experienced a power surge, common signs include the TV going completely dead, the standby light no longer coming on, a distorted screen with lines, or the TV repeatedly switching itself off and on. Gradual damage can also show up as unresponsive HDMI ports, sluggish Smart TV performance, or unexplained audio issues.
At Refitec Kenya, our technicians perform thorough diagnostics to identify every component affected by a surge, not just the obvious one. We repair all major TV brands including Samsung, LG, Sony, Hisense, TCL, Skyworth, Vitron, Vision, and more — and we back every repair with a warranty.
Final Word from Refitec Kenya
A surge protector is not a luxury — it is the most cost-effective TV insurance you can buy in Kenya today. Given the realities of our power grid, it is a matter of when, not if, your home experiences a voltage spike. Spend KES 1,500 on a quality surge protector now, and avoid spending KES 10,000 or more on a repair later.
