The Gigiri service area — roads & estates we serve
We operate across Gigiri and its immediate environs (useful for on-site calls): Limuru Road (including the Village Market area), UN Avenue / United Nations Complex, Gigiri Drive, and adjacent neighborhoods such as Runda, Nyari, Rosslyn and parts of Muthaiga. We also serve feeder streets and residential compounds around these points. (Local info sources: area listings & Village Market location).
Common TV problems — each explained, diagnosed, and fixed
1) Cracked or physically damaged screen / panel replacement
What you’ll see: spiderweb cracks, black blotches, vertical/horizontal lines, dead pixels, or a completely black screen with audio still playing.
Root causes: impact damage, pressure during transport, manufacturing defects, thermal stress over time which weakens the glass/plastic substrate.
Technical breakdown (diagram-style, text):
- Front glass / protective layer → Polarizer → LCD / OLED panel → Backlight (for LCD) → T-Con board → Mainboard.
- If the front layer is shattered but the panel’s internal layers remain intact you may get partial image; if the LCD glass matrix is damaged you’ll see black blotches where pixels no longer receive correct voltages.
Diagnosis steps: visual inspection, power-on test (listen for sound), straightening test (slow rotation to see lines), measure panel voltages.
Solution: panel replacement — match exact panel model (manufacturer part number), re-seat T-Con connections, and test for uniform backlight and color calibration. We keep common panel SKUs for popular models; otherwise we source quickly.
Notes: panel replacements can be the most expensive repair because panels are high-value assemblies; we recommend replacing with tested OEM or high-quality equivalent to maintain color & HDR performance.
2) Backlight failure (LED strips / CCFL tubes) — common in LCD TVs
What you’ll see: dim screen, very low brightness even at max, parts of screen dark while others visible, or image visible with flashlight (indicating panel still image-forming but no backlight).
Root causes: aged LED strips, failed inverter/driver circuits, power surge, poor ventilation causing heat damage, or failing capacitors on the backlight driver board.
Technical breakdown (diagram-style):
- Power Supply → Backlight Driver/Inverter → LED strips (edge or direct array) → Light Guide Plate (for edge-lit units).
- The power supply provides stable DC → driver converts/stabilizes current and adjusts PWM dimming → LED strips illuminate the panel from behind/edge.
Diagnosis steps: measure DC rails to backlight driver, use LED tester on strips, check for pulse-width modulation (PWM) signal from driver, inspect electrolytic capacitors on driver board.
Solution: replace failed LED strips or CCFL tubes, replace faulty backlight driver/inverter board, or repair caps and MOSFETs on driver. For edge-lit units, often the LED strips come as replaceable rails; for direct-lit arrays, we replace the whole array module. We stock common LED strip types and drivers for major brands.
Maintenance tip: avoid covering vents; keep the TV in a cool, ventilated position. A simple schedule of dusting vents and checking for loose cables every 3–6 months will extend backlight life.
3) Power issues — TV won’t turn on or keeps restarting
What you’ll see: no power, red standby light only, intermittent boot, clicking sound, or immediate shut-off after power-on.
Root causes: failed power supply capacitors, blown fuses, shorted MOSFETs, failing standby circuit, or external power fluctuations. Repeated surges can slowly degrade components until failure.
Technical breakdown (diagram-style):
- Mains AC → EMI filter → Rectifier → Bulk DC (electrolytic caps) → Switch-mode regulators → Standby rail & main rails.
- Standby microcontroller and IR receiver live on low-voltage standby rail; pressing power triggers main power-up sequence. Faulty regulator or low bulk capacitance can prevent stable boot.
Diagnosis steps: measure AC input, check for the presence of standby voltage (often 5 V or 12 V), test main rail voltages, inspect electrolytic capacitors for bulging or leakage.
Solution: replace faulty capacitors and damaged power MOSFETs, repair PCB traces or replace entire PSU board when necessary. Install surge protectors and recommend UPS for high-value units.
Maintenance tip: use a surge-protected power strip and avoid frequent on/off switching.
4) Mainboard failure — no HDMI, apps not loading, or no signal processing
What you’ll see: blank screen with no signal detected, HDMI inputs not recognized, OS/firmware crashes on smart TVs, or loss of remote/IR response.
Root causes: corrupted firmware, failed electrolytic caps on the mainboard, damaged HDMI connectors, or degraded eMMC/NAND storage in smart TV OS modules. Power surges and thermal cycles accelerate failure.
Technical breakdown (diagram-style):
- Inputs (HDMI/USB) → Input processors → Main SoC (system-on-chip) + GPU → eMMC/NAND storage for OS → T-Con + Audio Codec.
Diagnosis steps: test HDMI with known-good cable/console, inspect physical ports, attempt firmware re-flash via USB, check for boot logs or LED error blinks, measure voltages to SoC rails.
Solution: firmware updates or re-flashing (if available), replace mainboard (common when SoC or storage fails), repair or replace HDMI ports. We keep a stock of common mainboards for popular models and can program region-specific firmwares where appropriate.
Pro tip: back up smart-TV settings where possible and follow manufacturer update instructions to avoid corrupted updates.
5) T-Con (Timing Control) board faults — image artifacts, vertical lines, or color blocks
What you’ll see: vertical lines, color bands, image tearing, or partial image. Sound may remain OK.
Root causes: loose LVDS cable between mainboard and T-Con, failing components on T-Con, or panel connector corrosion.
Technical breakdown (diagram-style):
- Mainboard LVDS/EDP output → T-Con board (timing & voltage mapping) → panel’s row/column drivers.
Diagnosis steps: reseat LVDS cable, inspect connectors for corrosion, swap in a known-good T-Con (if available), measure gate and source voltages to panel.
Solution: replace or reflow T-Con board, clean/replace ribbon connectors. T-Con replacements are often lower-cost than full panel swaps.
6) Audio problems — no sound or distorted audio
What you’ll see: screen fine but no audio, distorted speakers, or audio cutting out.
Root causes: faulty audio amplifier, blown speaker, bad firmware settings, or output socket failures.
Diagnosis steps: test optical/ARC and external speakers, measure headphone jack continuity, test internal amp rails.
Solution: repair/replace audio amp IC, replace speakers, or repair audio jacks. For convenience we can add external soundbar integration if internal speaker repair is uneconomical.
7) Smart TV software & app failures — buffering, crashes, or update loops
What you’ll see: stuck on logo, apps crash, slow UI, or failed updates.
Root causes: corrupted firmware, insufficient storage in the TV’s flash memory, network problems, or outdated apps.
Technical breakdown:
- Network → OS (Linux/Android/webOS/Tizen) → App layer → Rendering engine → Main SoC.
Diagnosis steps: factory reset, test with fresh network, re-flash firmware, check eMMC health.
Solution: firmware re-flash, storage replacement (rare), advise on network / Wi-Fi improvements, or recommend external streaming devices if TV hardware is underpowered.
How Refitec diagnoses — the systematic approach
- Triage (5–10 mins): quick symptom verification (power, sound, visible image).
- Non-invasive tests: check cables, remote, power outlet, and use test patterns.
- Open inspection: internal board inspection for bulged caps, burn marks, or loose connectors.
- Component-level testing: voltage rails, continuity, signal probing.
- Repair or replacement: we repair at component level where safe and cost-effective; otherwise we replace entire modules (PSU, mainboard, T-Con, panel).
- Calibration & burn-in: color calibration and 24–48 hour burn-in for replaced panels/backlights to detect early failures.
- Handover & warranty: documentation of work and warranty on parts/labor.
Spare parts — what we stock and how we source
We keep a rotating inventory of common parts for Samsung, LG, Sony, Hisense, Panasonic, Philips, TCL, and other popular brands:
- Backlight LED strips & drivers
- Power supply boards & capacitors
- T-Con boards & LVDS cables
- Mainboards & HDMI port assemblies
- Screen panels (popular sizes/models) or fast-sourced replacements
- Audio speakers & jacks
For rare parts we source through trusted distributors and provide a lead-time estimate before ordering. Parts fitted are tested and come with a limited parts warranty.
On-site vs workshop — what’s best?
- On-site (at your home/office in Gigiri): ideal for simpler fixes — HDMI port cleaning, firmware updates, software resets, power/standby fixes, or replacing external connectors. Saves you the trouble of transporting large screens.
- Workshop (our facility): recommended for panel replacements, complex board repairs, and any job requiring soldering, reflow, or extended burn-in testing.
Safety & privacy in diplomatic/residential areas
We respect privacy and security protocols in Gigiri’s diplomatic compounds. Our technicians carry ID and follow access and confidentiality guidelines. For high-security buildings (embassies, UN offices), we coordinate with facility security and can perform scheduled, escorted repairs.
Preventive maintenance — keep your TV healthy
- Ventilation: keep 10–15 cm clearance at vents; avoid enclosed cabinets without airflow.
- Dust control: vacuum vents with soft brush every 3 months; use filtered air if possible.
- Power protection: use surge protectors or UPS especially during storms or when voltage fluctuations occur.
- Firmware hygiene: apply manufacturer updates when stable; avoid interrupting updates.
- Avoid touching the screen surface with pressure; transport face-up and supported.
- Annual check: capacitor health check on power supply for TVs older than 5 years.
Typical repair timelines & cost guidance (estimates)
- Diagnostic & minor fixes (software, ports, small parts): same day to 48 hours.
- Backlight or T-Con replacement: 2–5 days (depending on parts).
- Panel replacement or mainboard replacement: 3–10 days (panel availability is the main factor).
Costs vary widely by TV size and brand — we provide transparent quotes before any work. In many cases repairing a board or backlight is more economical than full panel replacement.
