TV Screen Flickering Repair in Nairobi by Refitec

Televisions are no longer just entertainment gadgets—they are central hubs for family bonding, information, business presentations, and even smart home integrations. However, one frustrating issue that many households and businesses in Nairobi face is TV screen flickering. This is when the screen intermittently flashes, dims, brightens, or shows unstable images, disrupting the viewing experience.

At Refitec (0704843613, refitec.co.ke), we specialize in TV screen flickering repair in Nairobi, handling all brands and models including Samsung, LG, Sony, TCL, Hisense, Panasonic, Skyworth, Vitron, and more. With years of expertise, access to genuine spare parts, and skilled technicians, we provide reliable repair services across all Nairobi neighborhoods.

In this detailed guide, we’ll discuss the possible problems that cause TV screen flickering, their solutions, and how Refitec ensures long-lasting fixes.


1. Faulty Backlight System

One of the most common reasons for TV screen flickering is a failing LED backlight system. Modern TVs rely on LED strips to provide uniform illumination behind the LCD panel. When these strips begin to fail, the screen may flicker, dim, or show uneven brightness.

  • Symptoms: Brightness fluctuations, dim patches, or complete backlight failure.
  • Causes: Overheating, power surges, or prolonged use at maximum brightness.
  • Solution: Refitec technicians diagnose the defective backlight strips using specialized equipment and replace them with genuine LED backlight sets. We also apply thermal paste and cooling solutions to extend the lifespan of the new backlights.

2. Loose or Damaged Cables

Sometimes, the issue is as simple as a loose cable connection inside the TV or with external devices. HDMI, LVDS (Low Voltage Differential Signaling) cables, or ribbon connectors that transmit signals from the main board to the display can loosen or get damaged.

  • Symptoms: Screen flickers when touched, when adjusting cables, or only with certain inputs.
  • Causes: Frequent plugging/unplugging, poor-quality cables, or internal connector wear.
  • Solution: At Refitec, we check all internal and external connections, replace faulty cables, and ensure proper grounding. We also recommend high-quality HDMI 2.1 cables for modern TVs to prevent recurring issues.

3. Power Supply Problems

Your TV’s power supply board converts household AC voltage into DC power for different TV components. A weak or failing power supply can cause the screen to flicker, especially under high load conditions.

  • Symptoms: Flickering during brightness changes, random shutdowns, or buzzing sounds from the TV.
  • Causes: Capacitor failure, voltage fluctuations in Nairobi estates, or aged components.
  • Solution: Refitec tests the power supply board using multimeters and oscilloscopes, replacing capacitors, fuses, diodes, or entire boards when necessary. We also advise customers to use voltage stabilizers or UPS systems to protect TVs from Nairobi’s frequent power surges.

4. Inverter Board Malfunctions

For certain older LCD models, the inverter board regulates the backlight brightness. A faulty inverter may cause the backlight to flicker or fail intermittently.

  • Symptoms: Screen flickers more when brightness is increased.
  • Causes: Aging transistors, moisture damage, or overheating.
  • Solution: Our experts at Refitec repair or replace the inverter board and reinforce cooling mechanisms to prevent repeat issues.

5. Graphics Processing Unit (GPU) or T-Con Board Failure

The Timing Control (T-Con) board and GPU are critical in managing how images are displayed on the screen. A malfunction here leads to horizontal/vertical flickering lines, jittery images, or stuttering visuals.

  • Symptoms: Flickering lines across the screen, distorted images, or ghosting effects.
  • Causes: Heat stress, poor soldering joints, or firmware corruption.
  • Solution: Refitec re-solders BGA chips, updates firmware, and if needed, replaces the T-Con board with an original spare part.

6. Refresh Rate & Software Issues

Sometimes, flickering is not a hardware fault but a software or settings problem. A mismatch between the TV refresh rate (e.g., 60Hz vs. 120Hz) and the content being played may cause flickering.

  • Symptoms: Flicker only on specific apps, channels, or devices (e.g., gaming consoles).
  • Causes: Incorrect TV settings, outdated firmware, or incompatible HDMI source settings.
  • Solution: Our technicians adjust picture settings, update TV firmware, and calibrate refresh rate to eliminate flickering. We also educate users on optimal settings for streaming devices like Netflix, Showmax, DSTV, and gaming consoles.

7. Overheating and Ventilation Issues

Like any electronic device, TVs generate heat during operation. When cooling is inadequate, components expand and contract, causing unstable connections that may lead to flickering.

  • Symptoms: Flickering after prolonged use, hot TV casing, or automatic shutdowns.
  • Causes: Blocked ventilation, dust accumulation, or defective cooling fans (for high-end models).
  • Solution: Refitec performs deep cleaning, replaces thermal pads, and ensures proper ventilation. We also recommend wall-mounting TVs in Nairobi apartments where airflow is restricted.

8. External Interference

In some cases, flickering is caused by external electrical interference. Nairobi households often run multiple appliances such as fridges, microwaves, and washing machines on the same circuit, which may disrupt the TV’s stable current.

  • Symptoms: Flickering only when other appliances are running.
  • Causes: Poor wiring, grounding issues, or electromagnetic interference.
  • Solution: Our team checks the wiring system, installs surge protectors, and advises on dedicated circuits for high-end TVs to eliminate interference-related flickering.

9. Aging Display Panels

As TVs get older, their LCD or OLED panels degrade. This natural wear and tear can cause flickering, dead pixels, or color inconsistencies.

  • Symptoms: Persistent flickering regardless of settings or input source.
  • Causes: Pixel burnout, OLED burn-in, or aging liquid crystal layers.
  • Solution: Depending on the severity, Refitec either repairs the panel (if minor) or recommends screen replacement with genuine parts.

10. Environmental Factors

Humidity, dust, and temperature changes—common in certain Nairobi estates—can affect sensitive TV electronics. Moisture leads to short circuits, while dust buildup causes overheating and signal interference, leading to flickering.

  • Solution: Refitec provides preventive maintenance such as internal cleaning, moisture treatment, and conformal coating application to protect TVs in Nairobi homes.
