TV Screen Replacement in Nairobi — A Complete Guide (by Refitec)

Contact: Refitec — 0704843613 • refitec.co.ke

Replacing a TV screen is one of the most important and delicate services a repair shop can offer. In Nairobi, households and businesses rely on clear, large-format displays for entertainment, news, sports, and presentations — so when the screen cracks, blacks out, or develops permanent lines and dead pixels, the impact is immediate and tangible. This long-form guide explains how Refitec approaches TV screen replacement in Nairobi: how we diagnose problems, when replacement is necessary (vs repair), what types of screens and technologies are involved, how we source parts, the restoration process, quality and warranty considerations, maintenance tips, and what owners of popular TV brands and models should expect. Each brand and model family is discussed in its own paragraph to help you identify likely issues and sensible replacement options.

Why screens fail — common causes

TV screens may fail for many reasons. Physical impact is the most obvious — accidental knocks, falls, or something heavy striking the panel will crack the glass or damage the internal layers. Thermal stress can cause delamination or black spots: when a screen experiences repeated heating and cooling cycles, the adhesive layers between the glass, polarizers, and panel can separate. Power surges and faulty power supplies may damage the display driver electronics, manifesting as lines, flicker, or complete black screens despite the TV powering on. Manufacturing defects, though less common on modern sets, still occur and sometimes show up after months or years as dead zones or color inconsistencies. Liquid spills and moisture ingress, especially in humid environments or homes with children, are another frequent cause. Finally, age-related failure of backlights (for LCD/LED TVs) or degradation of organic materials (in older plasma or some OLED panels) can cause dimming, color shifts, or patchy illumination.

When to replace the screen vs repair other components

Not every visual issue requires a full screen replacement. Many issues are located in the power board, T-con (timing controller) board, mainboard, or the backlight assembly. If the TV has power and the panel is intact but shows vertical/horizontal lines, color faults, or intermittent blackout, the issue can often be resolved by repairing or replacing logic boards, T-con, or backlight strips. However, when the glass is cracked, or the LCD matrix itself is physically damaged, or the OLED substrate has burn marks, replacement of the entire panel assembly is necessary. Another clear indicator for replacement is widespread dead pixels or permanently black sections that persist across inputs and remain after soft resets — these are symptoms of panel failure. Refitec always starts with a thorough diagnostic: we test inputs, measure voltages, examine the T-con output, and isolate whether the problem originates in the electronics or the panel itself before recommending replacement.

Types of screen technologies — what changes in replacement

Understanding screen technology helps you appreciate the difference between replacing a backlight, replacing a T-con, and replacing an entire panel.

• LCD / LED-LCD (Twisted Nematic, IPS, VA): Most flat-screen TVs in Nairobi are LCDs with LED backlighting. Replacement often involves the panel assembly (LCD + front glass + polarizers) if the matrix is cracked. Backlight-only repairs are possible when brightness failure is caused by worn LED strips or inverter issues (in older CCFL backlights). T-con or mainboard faults are cheaper fixes when the panel is physically intact.
• QLED / Quantum Dot-enhanced LCD: Fundamentally LCDs with quantum-dot color enhancement; panel replacement is similar to LCD/LED.
• OLED: Organic Light Emitting Diode panels emit their own light per pixel. Because each pixel is an organic diode, severe burn-in or substrate damage can necessitate full panel replacement. OLED panels are more expensive and fragile; sourcing genuine OEM OLED panels is critical for color and lifespan.
• Plasma (legacy): Rare now, but plasma panel repairs are often impractical due to scarcity of parts; replacement is usually not cost-effective.
• MicroLED and MiniLED: Newer, premium technologies. MiniLED uses many small LEDs as the backlight — backlight repair is more complex but sometimes possible; MicroLED is modular and typically beyond local repair scope for replacement.

Refitec’s technicians apply industry-standard ESD-safe handling procedures when removing/replacing panels and protect the delicate flex cables and connectors that sit between the T-con and the panel.

Sourcing parts in Nairobi: OEM vs aftermarket

A critical part of screen replacement is where the replacement panel comes from. Original Equipment Manufacturer (OEM) panels — the exact panel model that came with the TV from the factory — ensure the best match in color reproduction, bezel fit, connectors, and long-term reliability. However, OEM panels for certain models can be expensive or lead time–dependent, especially for older or imported models.

Aftermarket and refurbished panels are more economical and sometimes provide a viable option when OEM panels are unavailable. The tradeoffs include potential color calibration differences, mismatched backlight characteristics, and possibly shorter lifespans. Refitec prioritizes OEM panels where possible; when OEM is not available we supply high-quality aftermarket panels tested for compatibility and reliability. For older models where parts are scarce, a refurbished panel from a donor TV can be an acceptable solution.

In Nairobi, logistics matter: we source parts from authorized distributors, regional parts houses in Kenya and East Africa, and vetted international suppliers. We inspect each incoming panel for mechanical and electrical integrity before installation and run calibration post-install to match factory color profiles as closely as possible.

The diagnostic and replacement workflow used by Refitec

1. Initial remote triage: You call or message (0704843613 / refitec.co.ke) and give symptoms and photos. Many simple fixes can be identified quickly (e.g., cracked glass visible in a photo).
2. In-person inspection and testing: A technician performs a hands-on diagnostic: power checks, board testing, T-con output, and panel inspection. We disconnect unnecessary inputs and test the panel with known-good boards when possible to isolate the fault.
3. Quote and options: We present clear options — repair (board, backlight), OEM panel replacement, aftermarket/refurbished panel — plus transparent cost factors. We explain risks and warranty differences.
4. Order and procurement: If a replacement panel is required, we order the correct part and keep you updated (note: we do not provide fixed lead-time estimates in writing; we will tell you when parts arrive).
5. Replacement and calibration: The panel replacement is performed in an ESD-safe environment. We test connections, secure the panel, reinstall the board assemblies, and run calibration and burn-in routines to ensure stable color and brightness.
6. Final testing and handover: We perform multi-hour stress tests (video loops, color bars) and test the TV through its common inputs (HDMI, USB, aux) before returning it to you. Documentation of the replaced part and any warranty details is supplied.

Cost factors to expect (what drives the price)

Several factors influence the cost of a screen replacement:

• Screen size and technology: Larger screens and OLED/QLED panels command higher prices than smaller LCDs. Ultra-thin high-end panels cost more to source and fit.
• Brand and model rarity: Mainstream models (e.g., recent Samsung, LG, Sony) often have readily available OEM parts; niche or older models require special sourcing and cost more.
• New OEM vs aftermarket/refurbished: OEM panels increase the parts bill; refurbished donor panels reduce cost but bring more uncertainty.
• Labor complexity: Curved panels, ultra-thin bezels, or designs requiring disassembly of many components can increase labor time and cost.
• Warranty and testing: Replacement with an OEM panel usually includes a better parts warranty; extended calibration and burn-in testing may be included or billed separately.

Refitec provides itemized quotes so you can see parts and labor broken out clearly and make an informed decision.

Quality assurance and warranty

Replacing a screen is only useful if the result is reliable. Refitec stands behind installations with a warranty on both parts (as provided by the panel supplier) and workmanship. We perform post-replacement calibration, check for stuck or dead pixels against industry standards, and stress-test the unit. If an issue arises related to the replacement within the warranty period, we will repair or replace per warranty terms. Note: warranty terms differ for OEM vs aftermarket parts — we document these differences before work begins.

Safety, transport, and logistics in Nairobi

Moving and handling large TVs requires care. When you bring a TV to our workshop or when we perform on-site service, we advise clearing a safe workspace, having a second person to help lift, and removing stands or wall mounts before transport if possible. If the TV is wall-mounted, our technicians can safely take it down and remount after replacement. For on-site replacements, we check the wall bracket for load integrity — a loose bracket can risk damage to a new panel.

Refitec follows safe transport practices: cushioned crates, foam padding, and secure vehicle transport to avoid additional damage during transit. We also take care to protect your floors and furnishings during the service visit.

Maintenance and care after replacement

After a screen replacement, owners should take a few simple precautions to protect their investment:

• Keep liquids away from the TV and avoid placing drinks on top of low stands.
• Avoid prolonged static high-contrast images that can lead to burn-in on OLED screens (for example: leave a moving screensaver on when streaming is paused).
• Use a surge protector to reduce the risk of power-surge related damage.
• Dust the TV with a microfiber cloth; avoid ammonia-based cleaners or paper towels which can scratch polarizers.
• For wall-mounted sets, ensure the bracket is properly rated for the TV’s weight and that ventilation space is maintained behind the TV.

Refitec provides aftercare advice specific to your new panel and can schedule performance checks if needed.

Brand-specific considerations (each brand/model discussed separately)

Samsung — Crystal UHD, QLED, The Frame, and older LED models

Samsung is among the most common brands in Nairobi. Their panel lineup ranges from entry-level Crystal UHD and standard LED-LCDs to higher-end QLED and The Frame models. QLED models use quantum dots to enhance color but remain LCD-based; replacement panels for QLEDs must match the original QLED panel family to maintain color fidelity. The Frame models have custom bezels and mounting systems; replacing a Frame panel requires attention to bezel fit and the magnetic trim. Samsung’s replacement parts are generally available from regional distributors for common sizes; Refitec keeps a stock of frequently used Samsung panels and T-con boards. For Samsung sets that display vertical lines or have sections of the image missing but no physical cracks, Refitec first inspects the T-con and LVDS flex cables — loose or damaged flex cables cause symptoms that mimic panel failure.

LG — OLED (C/B series), NanoCell, and standard LEDs

LG is the leading manufacturer of OLED panels used in many premium sets globally. LG OLEDs (C-series, B-series, G-series) are prized for deep blacks and wide viewing angles. Replacing an OLED panel is costlier than replacing an LCD panel because the panel itself is expensive and fragile. LG’s NanoCell and LED ranges are LCDs with different color technologies and backlight designs. For LG panels with image retention or burn-in, we advise owners on software-level remedies (pixel shift, brightness adjustments) for minor cases, but permanent burn-in often requires panel replacement. Refitec sources LG OLED panels from authorized channels to ensure proper color balance and longevity.

Sony — BRAVIA series (X, A, KD models)

Sony’s BRAVIA TVs are known for advanced processing (Motionflow, X-Reality) and proprietary panel pairings. Sony often uses panels produced by other manufacturers but tuned to Sony’s specifications. Replacement for Sony sets must match both the physical connector layout and the TV’s firmware expectations. Sony panels for popular sizes and model lines are usually available but may carry a premium. When customers report black areas or flicker on a Sony BRAVIA, Refitec technicians first test firmware, HDMI input behavior, and the mainboard before committing to panel replacement.

Hisense — ULED, entry-level LCDs

Hisense offers value-focused TVs under “ULED” branding and conventional LCD models. Hisense panels are more variable in sourcing; many are OEM-sourced from regional suppliers. Replacement panels are often available as direct-fit aftermarket units. Because Hisense models are common in Nairobi, Refitec maintains a relationship with suppliers who stock compatible parts, which can speed up repairs while keeping costs reasonable.

TCL — 6-Series, Roku TV models

TCL’s collaboration with Roku has made their TVs popular in the Kenyan market. TCL’s panel sourcing varies by region and model; some use panels that are shared with other brands. For TCL TVs displaying lines or dead pixels, technicians verify the firmware and external devices first — software-level HDMI handshake issues sometimes look like panel faults. When a panel replacement is required, Refitec sources compatible panels and ensures the TV’s firmware and calibration are correctly applied post-replacement.

Panasonic — Viera (legacy), LED models

Panasonic’s Viera line includes older plasma models and modern LCD/LED sets. Plasma panels are now effectively obsolete and often not practical to replace due to part scarcity. For modern Panasonic LED sets with cracked glass or dark patches, Refitec evaluates OEM replacement availability; when not available, we discuss the economics of replacement vs purchasing a new set.

Philips — Ambilight models and standard LED ranges

Philips sets with Ambilight have additional wiring and LED modules along the bezel that provide ambient lighting. When replacing a Philips panel, it’s important to ensure Ambilight modules and their control boards are compatible and connected properly. For non-Ambilight Philips TVs, panel replacement follows standard procedures. Refitec tests Ambilight functionality after replacement to ensure the full user experience is restored.

Sharp and other niche brands

Sharp TVs and other niche brands have loyal followings; panel replacement depends on model age and availability. Sharp’s older LCD modules can sometimes be sourced from regional distributors. Refitec advises customers on the viability of replacement versus replacement of the entire TV when parts are scarce or very expensive.

Vizio, RCA, and imported budget brands

These brands are less common in Nairobi but do appear in some households. Panels for these sets may be hard to source locally. Refitec evaluates whether a high-quality aftermarket aftermarket panel or a donor panel is the sensible option and documents the expected tradeoffs.

Specific model-family notes (examples)

• Samsung QLED (Q60/Q70/Q80 and above): These are high-performance LCDs; replacement panels from Samsung or authorized suppliers preserve HDR tone mapping and color volume. QLED panels require correct firmware pairing for optimal HDR performance — Refitec ensures this during the rebuild.
• LG OLED (C-series, B-series): OLED replacement panels are expensive and delicate. We recommend OEM panels to avoid color shifts and lifespan variations. If burn-in is present, we discuss long-term expectations even after replacement — e.g., brightness settings and content habits that minimize recurrence.
• Sony X90J / X95K: These often use full-array local dimming LED backlights with advanced processing. Replacing the panel means carefully recalibrating local dimming circuits and verifying the mainboard communicates correctly with the panel.
• TCL 6-Series / Roku-branded models: Frequent in budget-conscious households. Replacement panels often come from shared factories — compatibility is usually straightforward, but calibration post-install is important for satisfying picture quality.
• Hisense ULED / U7 Series: ULED models can require careful tuning of the quantum-dot or local-dimming behavior — Refitec performs color checks after replacement to match expected color temperature and gamma.

On-site vs workshop replacement — choosing the right approach

Small-to-medium TVs are often safer to handle in a workshop setting where technicians have the right tools, lifts, and clean benches. However, for large-screen TVs (65” and up) or in cases where the TV is mounted in a fixed position (e.g., corporate boardroom), on-site replacement is often necessary. On-site replacements require more preparation: secure mounts, floor protection, and sometimes an assistant from the customer to help with removal. Refitec performs on-site replacements when necessary and documents safety checks before and after installation.

Environmental responsibility and end-of-life panels

Old panels and damaged glass must be disposed of responsibly. LCD panels contain polarizers and adhesives; OLED panels contain organic materials and electronics. Refitec follows local recycling and disposal best practices where possible, segregating electronic waste, and partnering with certified recyclers for responsible handling. When a replacement is not economic, we’ll advise you whether recycling or trade-in options are available.

Troubleshooting common symptoms (before assuming panel replacement)

• Black screen but power LED on: Check for backlight failure, T-con issues, or mainboard HDMI handshake. A quick test is to shine a bright torch across the screen — if faint image is visible, backlight or inverter is the issue, not the panel.
• Lines across the screen: Often caused by T-con failure, loose LVDS cables, or panel matrix failure. Re-seating cables and testing with a known-good board can isolate the cause.
• Dead pixels / stuck pixels: Small numbers of dead pixels may be acceptable per manufacturer tolerances. Extensive clusters typically require panel replacement.
• Color tint or imbalance: Could be a failed color filter, aging backlight (in LED-LCD), or calibration issue. A professional calibration may resolve some issues without panel replacement.
• Burn-in (OLED): Persistent ghost images or permanent brightness reduction in parts of the screen indicate burn-in. Replacement is the straightforward remedy, followed by user guidance on preventing recurrence.

How Refitec handles warranty claims and second opinions

If your TV is under manufacturer warranty, we recommend contacting the manufacturer first — many warranties require authorized service centers for panel replacement eligibility. Refitec can assist by providing diagnostic reports and coordinating with manufacturer-appointed technicians when required. If you have an out-of-warranty TV or you need a second opinion, Refitec offers a transparent diagnostic report that details what was done and why replacement is recommended, so you can compare options.

Real-world examples and case studies (typical scenarios we handle)

• Cracked panel from accidental impact: A 55” Samsung Crystal UHD dropped from a stand. The glass was shattered and the LCD matrix compromised. Refitec sourced an OEM Samsung panel, replaced it, recalibrated color and gamma, and tested all inputs. The TV regained factory-like picture quality.
• Vertical lines after power surge: A Sony BRAVIA displayed vertical lines after a lightning event. The T-con board was damaged; replacing the T-con restored the image without replacing the panel.
• Burn-in on OLED: A family’s LG C-series with news tickers showed image retention in the lower third of the screen after years of static logos. The OLED panel required replacement. Post-replacement, Refitec advised on brightness settings and automated pixel-shift features to reduce risk going forward.
• Backlight failure on an older LED TV: A Panasonic LED set became dim. The panel and LCD were intact; Refitec replaced backlight LED strips and power driver components, restoring brightness at a fraction of the cost of full panel replacement.

These case studies reflect typical paths from diagnosis to resolution, emphasizing that not every symptom requires a full screen swap.

Questions to ask your repair provider (and to which Refitec gladly responds)

• Will you source an OEM panel or provide an aftermarket/refurbished unit?
• Can you show proof of part authenticity and provide a part number?
• What is the warranty on parts and workmanship?
• Do you perform calibration after replacement?
• How will the TV be protected during transport and installation?
• Can you provide a diagnostic report in writing before you proceed?

Refitec’s customer service team answers these questions transparently and supplies documentation with every repair.

How to prepare before calling for screen replacement

• Note the TV brand, model number, and serial number (usually on the back label).
• Take clear photos of the screen (from front and back) showing visible damage.
• Note when the issue began and any events (power surge, drop) that preceded it.
• Disconnect peripherals and backup any settings or Smart TV app accounts if possible.

Providing this information speeds up remote triage and helps us bring the right parts and tools if we visit your home or office.

Final thoughts: value, longevity, and making the decision

Replacing a TV screen restores the full viewing experience — picture fidelity, color accuracy, and brightness. For high-end TVs (OLED, premium QLED, large-screen Sony/ LG panels), replacement is often a sensible investment if the appliance is otherwise in good condition and suits your needs. For older, lower-cost sets, the economics sometimes favor purchasing a new TV rather than sourcing rare panels. Refitec helps customers weigh the factors — cost, part availability, expected remaining lifespan — and provides a fair recommendation.

Refitec’s approach to screen replacement in Nairobi centers on expertise, transparency, and customer service: accurate diagnostics, responsible sourcing of parts, meticulous installation, and thorough testing. Whether you have a cracked Samsung Crystal UHD, an OLED with burn-in, or a business display needing urgent attention, Refitec aims to restore your screen to peak performance while explaining every option in plain language.
