Introduction

In today’s modern homes, televisions are no longer just entertainment boxes—they are the centerpiece of family living rooms, a source of news, education, movies, and even smart connectivity.

⚡ Common TV Problems and Expert Solutions

1. TV Not Powering On

One of the most common issues we encounter in Uthiru homes is a television that simply won’t turn on. This can be caused by several underlying problems:

• Faulty Power Supply Board: Modern TVs use a switch-mode power supply (SMPS). If the capacitors, transformers, or MOSFETs fail, the TV won’t receive power.
• Blown Fuse or Capacitor Damage: Surges from unstable electricity, common in Nairobi estates, often blow internal fuses or damage electrolytic capacitors.
• Defective Main Board: If the logic circuitry is damaged, signals from the power button won’t reach the rest of the system.

Solution by Refitec:
Our technicians perform a systematic voltage tracing from the power socket to the power supply board, checking if the 5V standby voltage is present. If not, we replace the damaged capacitors, fuses, or power board entirely with genuine spare parts available in stock.

Maintenance Tip: Always connect your TV to a high-quality surge protector or UPS system, especially in areas like Ndumbuini and Gathiga, where power fluctuations are common.

2. No Picture but Sound is Working

When you can hear sound but the screen is black, this points directly to a display-related issue.

• Backlight Failure (in LED/LCD TVs): LEDs that illuminate the screen may burn out over time, or the LED driver circuit fails.
• Inverter Problems (for older LCDs): Fluorescent CCFL backlights rely on inverters, which often fail due to aging components.
• T-Con Board Failure: The timing control (T-Con) board manages image processing. A shorted IC or blown fuse here results in no picture.

Solution by Refitec:
We test LED strips with a multimeter in diode mode, checking continuity. If defective, we replace individual LEDs or the entire strip. For T-Con issues, we test LVDS cable continuity and replace damaged ICs.

Maintenance Tip: Keep brightness levels moderate to extend backlight life. Avoid running TVs at maximum brightness in estates like Muthua Estate, Uthiru 87, and Gitaru, where living rooms often have sufficient daylight.

3. TV Turns On Then Immediately Off

This symptom is called power cycling. It usually happens due to:

• Short-Circuit in Power Supply: Overcurrent protection shuts the TV down.
• Main Board Issues: Faulty firmware or bad ICs on the motherboard.
• Overheating Components: Dust buildup in estates along Waiyaki Way and Ndumbuini can cause poor ventilation.

Solution by Refitec:
We clean internal boards, replace burnt ICs, and if necessary, reflash the firmware using service ports like USB or JTAG.

Maintenance Tip: Ensure your TV has at least 2–3 inches of ventilation space at the back. Clean the vents regularly.

4. Distorted Images / Double Picture

Distorted pictures often mean an issue with the T-Con board or panel connections.

• Causes: Loose LVDS ribbon cables, shorted ICs, or faulty gamma correction circuits.
• Solution by Refitec: We reseat or replace LVDS cables, test T-Con voltages, and replace faulty ICs.
• Maintenance Tip: Never press hard on the screen when cleaning; it can damage internal layers and cause permanent distortion.

5. No Sound but Picture is Clear

This is typically due to:

• Faulty Audio IC: The sound amplifier IC can burn out.
• Speaker Damage: Paper cone speakers easily tear in humid conditions like Muthua and Gichagi areas.
• Loose Audio Settings: Muted or misconfigured sound settings.

Solution by Refitec:
We test the audio circuit path, replace damaged audio ICs, or install new OEM speakers from our spare parts inventory.

Maintenance Tip: Connect external sound systems via HDMI ARC or optical out to reduce strain on inbuilt speakers.

6. Lines on the Screen (Vertical or Horizontal)

This common Uthiru problem points to:

• Damaged Panel: Broken gate drivers.
• T-Con Board Failure: Poor gamma correction.
• Loose Ribbon Cable: Faulty connections between panel and T-Con.

Solution by Refitec:
We reseat ribbon cables, test gate driver voltages, and if needed, replace the entire panel.

Maintenance Tip: Always transport TVs upright. Never lay flat in pickups around Uthiru 87 and Ndumbuini, as panel stress causes line issues.

7. TV Remote Not Working

Sometimes the TV is fine, but the remote control won’t respond.

• Causes: Worn-out IR transmitter, dead batteries, or blocked sensor.
• Solution: We test remotes using smartphone cameras (infrared lights appear as flickers) and replace faulty remotes from our stock.
• Maintenance Tip: Keep remotes clean and away from spills.

8. Smart TV Apps Not Working

Modern smart TVs in Uthiru (LG WebOS, Samsung Tizen, Android TV) may freeze or fail to run apps.

• Causes: Outdated firmware, corrupted app cache, or insufficient memory.
• Solution: We update firmware, clear caches, and in some cases, reflash the main board.
• Maintenance Tip: Keep your TV connected to reliable Wi-Fi and update software regularly.
