Common TV Problems in Lavington and Their Solutions
We have seen and fixed every possible TV fault—especially in the Gitanga Road and Lavington area where many households have high-end brands like Samsung, LG, Sony, TCL, Hisense, Panasonic, Skyworth, and Vitron.
Here’s an in-depth look at the most common TV problems, their technical causes, and how we fix them.
1. TV Screen Repair and Replacement
Problem:
Your TV has visible cracks, color patches, lines, or complete blackout on the display.
Causes:
- Physical Damage: Accidental knocks, falls, or pressure on the screen.
- Electrical Surge Damage: High voltage can fry the display’s driver circuits.
- Liquid Damage: Spilled water or cleaning agents seeping into the panel layers.
- Panel Driver IC Failure: Damage to the integrated circuits that control pixel operation.
Technical Breakdown:
A TV screen consists of multiple layers:
[ Protective Glass Layer ]
[ Polarizing Film ]
[ Liquid Crystal Layer ]
[ TFT (Thin Film Transistor) Grid ]
[ Backlight Assembly ]
When cracks occur, they often disrupt both the outer glass and the internal liquid crystal or OLED layer, making the damage irreversible.
If the TFT layer is damaged, the pixel addressing system fails, resulting in lines or black sections.
Solution by Refitec:
- For minor glass surface damage, we can replace only the outer protective layer.
- For internal damage, we perform a full panel replacement using genuine brand-specific screens.
- After replacement, we run factory-level calibration to restore accurate colors and brightness.
2. Backlight Replacement
Problem:
The TV has sound but no picture, or the picture is very dim.
Causes:
- LED Backlight Burnout: Overheating causes individual LEDs to fail.
- Power Supply Faults: Insufficient voltage reaching the LED strips.
- Over-brightness Settings: Prolonged maximum brightness accelerates LED wear.
- Moisture Damage: Common in coastal areas but can happen in humid Nairobi weather.
Technical Breakdown:
The backlight system consists of:
[ LED Strips ]
[ Diffuser Panels ]
[ Reflective Sheet ]
The LED strips emit light that passes through the diffuser panels to evenly light the display.
If one LED fails, the strip’s circuit can break, leading to a black or dim screen.
Solution by Refitec:
- We disassemble the panel with dust-free, static-safe methods.
- Faulty LED strips are replaced with brand-matched replacements.
- The power board is checked to prevent recurrence.
- We perform luminosity calibration so brightness matches factory settings.
3. Power Issues (TV Not Turning On)
Problem:
Press the power button—nothing happens, no light, no sound.
Causes:
- Faulty Power Supply Board: Damaged capacitors, transformers, or fuses.
- Main Board Failure: Microprocessor or EEPROM corruption.
- Faulty Cables or Power Socket.
- Overvoltage Damage: From unstable Nairobi power grids.
Technical Breakdown:
The TV’s SMPS (Switched-Mode Power Supply) converts 220V AC into multiple DC voltages.
If this fails, the TV’s circuits starve of power.
Solution by Refitec:
- Replace damaged capacitors with low ESR, high-temperature-rated parts.
- Test and, if necessary, replace the entire power supply board.
- Install a surge protection system to safeguard against future damage.
4. Audio Problems (No Sound or Distorted Sound)
Problem:
The screen works perfectly, but there’s no sound, or the sound is muffled/distorted.
Causes:
- Speaker Damage: Physical wear or coil burnout.
- Audio Processing Chip Failure: On the main board.
- Loose Cable Connections.
Solution:
- Replace faulty speakers with genuine acoustic-matched replacements.
- Repair or replace the audio processing IC.
- Secure internal wiring.
5. HDMI / Signal Input Issues
Problem:
No signal from HDMI devices, flickering image, or input not detected.
Causes:
- Damaged HDMI Ports: Physical wear from repeated plugging/unplugging.
- Faulty Input Controller Chip.
- Firmware Corruption.
Solution:
- Replace damaged ports.
- Update or reinstall firmware.
- Repair mainboard input controllers.
Technical Maintenance Tips for Longer TV Life
- Use a Surge Protector: Nairobi’s power fluctuations can fry circuits.
- Avoid Maximum Brightness: Extend backlight life by keeping brightness at 50–70%.
- Clean with Care: Use a microfiber cloth and avoid liquid sprays directly on the screen.
- Allow Ventilation: Keep TVs away from enclosed cabinets to prevent overheating.
- Update Firmware Regularly: Ensures compatibility with new content formats.
