Now, let’s go deep into the common TV problems, causes, solutions, and maintenance tips.

1. TV Screen Problems – Cracks, Dead Pixels, and Lines on Screen

The TV screen is the most delicate and expensive component of your television. Common screen issues include:

• Cracked or physically damaged screens – caused by accidental falls, pressure, or impact.
• Dead pixels – small black spots that don’t display color due to failed sub-pixels.
• Horizontal or vertical lines – usually caused by faulty T-CON boards, loose ribbon cables, or internal short circuits.

Technical Explanation:

The screen is made of multiple layers—LCD/LED panel, polarizers, liquid crystals, and a backlight system. Any damage to the LCD glass or internal circuits leads to permanent defects.

Solution:

• Cracked screens require full screen replacement using genuine manufacturer parts.
• Dead pixels sometimes can be corrected by reprogramming or light massaging, but most need panel replacement.
• Lines on the screen can be fixed by replacing T-CON boards, re-seating ribbon cables, or changing the panel.

At Refitec Kikuyu, we stock original replacement screens and T-CON boards for major TV brands, ensuring long-term solutions.

2. Backlight Problems – Dim Screen or No Picture but Sound Works

One of the most common TV problems in Kikuyu homes is when the TV has sound but no picture. This is caused by a failure in the backlight system.

Causes:

• Burnt-out LED strips.
• Faulty backlight inverter board.
• Power surges damaging the LED drivers.

Technical Breakdown (Diagram Style Explanation):

• TV LED Backlight System
  1. Power Board supplies DC current.
  2. Backlight Driver/Inverter regulates voltage.
  3. LED Strips illuminate the LCD panel.
  4. If LEDs fail → screen stays dark.

Solution:

• We test the LED strips using specialized tools.
• Replace faulty LED strips or the inverter board.
• Add surge protection to prevent repeat failures.

We always use original LED backlight strips and provide a warranty for replaced parts.

3. Power Issues – TV Not Turning On

A very frustrating issue is when your TV fails to power on completely.

Causes:

• Faulty power supply board (capacitors blown, fuses burnt).
• Damaged power IC or MOSFET transistors.
• Motherboard short-circuit.
• Faulty power cable or socket.

Technical Breakdown:

• The power board converts AC (240V) to DC voltages (5V, 12V, 24V).
• If capacitors swell or ICs burn out, the TV won’t power up.
• Sometimes the standby LED blinks—indicating error codes.

Solution:

• Refitec technicians repair or replace power boards, ICs, and fuses.
• We use high-quality capacitors to ensure durability.
• For lightning-prone areas in Kikuyu (like Lusigetti and Ondiri), we recommend installing surge protectors.

4. Sound Problems – No Audio, Distorted Sound, or Static Noise

Another common issue is TV sound failure, where the screen works but audio is missing or distorted.

Causes:

• Faulty audio IC on the motherboard.
• Damaged speaker units.
• Loose HDMI/AV connections.
• Software glitches in smart TVs.

Technical Breakdown:

The audio IC processes sound signals from the main board to the amplifier, then to the speakers. If any stage fails, sound output is lost.

Solution:

• Replace faulty speakers or audio ICs.
• Re-solder loose connections.
• Perform firmware updates for smart TVs.

Refitec stocks replacement speakers and audio boards for all major brands.

5. HDMI & Port Problems – No Signal or Loose Connections

Smart TVs heavily depend on HDMI, USB, and AV ports for external devices. Over time, these ports get damaged.

Causes:

• Frequent plugging/unplugging.
• Physical damage to HDMI pins.
• Faulty input board.

Solution:

• Replace damaged HDMI/USB ports.
• Re-solder motherboard connections.
• Replace the entire input board if ports are burnt.

Refitec ensures high-quality port replacement that restores full functionality.

6. Software & Smart TV Problems

Modern smart TVs face software-related problems, including:

• Apps freezing.
• TV stuck on boot logo.
• Wi-Fi not connecting.
• Firmware corruption.

Solution:

• Firmware reinstallation.
• Mainboard software flashing.
• Resetting to factory settings.

Refitec uses official firmware updates for Samsung, LG, Sony, Hisense, TCL, and other brands.

7. Motherboard & Mainboard Repairs

The motherboard is the brain of the TV. When it fails, symptoms include:

• No picture, no sound.
• HDMI/USB not working.
• TV not responding to remote.

Technical Breakdown:

The motherboard contains:

• CPU & GPU – handle smart functions.
• Memory Chips – store firmware.
• ICs & Circuits – manage inputs/outputs.

Solution:

• Chip-level repair using soldering stations.
• Replacement of burnt ICs.
• Full motherboard replacement if beyond repair.

We keep motherboards for major TV brands in stock.

8. Remote Control & Sensor Problems

Sometimes, the issue isn’t the TV itself but the remote control or IR sensor.

Causes:

• Faulty remote batteries.
• Broken IR sensor on TV.
• Remote control damage.

Solution:

• Replace IR sensors.
• Provide replacement remotes.
• Calibrate TV sensor settings.

Preventive Maintenance Tips for Kikuyu Residents

To ensure your TV lasts long, Refitec recommends:

1. Use surge protectors to guard against Kikuyu’s frequent power fluctuations.
2. Avoid placing TVs near windows to reduce dust and humidity damage.
3. Clean ventilation grills to prevent overheating.
4. Update firmware regularly for smart TVs.
5. Handle remotes and ports gently to prevent damage.
