Common TV Problems and Technical Solutions

1. TV Not Powering On

Problem Description:
One of the most common complaints from Harambee Estate residents is that their TV won’t turn on. You press the power button, but nothing happens – no light, no sound, no display.

Technical Causes:

• Faulty Power Supply Board (PSB): TVs rely on their power supply board to convert AC voltage into low DC voltage required for the circuits. Burnt capacitors, faulty diodes, or blown fuses can cause complete power failure.
• Mainboard Issues: If the mainboard is shorted due to overheating or power surge, it prevents the TV from booting.
• Loose Power Cables or Damaged Socket: Sometimes, the issue is external – frayed cables, loose connections, or unstable sockets.

Solutions by Refitec:

• We first conduct voltage tests using a digital multimeter to confirm whether current is reaching the power board.
• If faulty capacitors are detected, we replace them with high-quality ones rated for higher endurance.
• For severe damage, the entire power supply board is replaced. We stock genuine Samsung, LG, Sony, TCL, Hisense, and Panasonic spare parts for reliable replacement.
• Safety checks are done to confirm stable grounding to prevent future failures.

Maintenance Tips:

• Always use a surge protector to shield your TV from Nairobi’s frequent power fluctuations.
• Avoid plugging too many devices into one socket, as this strains the circuit.

2. No Picture but Has Sound

Problem Description:
The TV powers on, sound plays perfectly, but the screen is black.

Technical Causes:

• Backlight Failure: LED/LCD TVs use backlight strips to illuminate the display. When these burn out, the screen goes dark.
• Inverter Board Issues: The inverter powers the backlight. A failure here means no illumination.
• Faulty T-Con (Timing Controller) Board: If the T-Con board malfunctions, it disrupts video signal processing, resulting in no image.

Solutions by Refitec:

• We shine a flashlight on the screen; if faint images appear, it confirms backlight failure.
• Faulty LED strips are carefully replaced. Unlike unskilled repairers who replace only one strip, we replace all for uniform brightness.
• Inverter board issues are solved by replacing MOSFETs or capacitors, or swapping the full board if severely damaged.
• T-Con board replacement is available from our spare parts inventory, ensuring quick restoration.

Maintenance Tips:

• Lower screen brightness during use to extend backlight lifespan.
• Avoid leaving static images on the screen for long, as this accelerates wear.

3. Distorted or No Sound

Problem Description:
The screen works fine, but there’s no audio or the sound is distorted.

Technical Causes:

• Blown Audio IC (Integrated Circuit): This small chip controls audio amplification. A power surge can burn it.
• Speaker Failure: Dust, moisture, or aging damages built-in TV speakers.
• Software Glitches: Outdated firmware may cause audio output failure.

Solutions by Refitec:

• We test the audio IC and replace it if faulty.
• If speakers are damaged, we replace them with original manufacturer spares.
• Firmware updates are installed for software-related audio failures.

Maintenance Tips:

• Connect your TV to an external sound system to reduce stress on built-in speakers.
• Keep the TV away from moisture sources to avoid corrosion of sound circuits.

4. Lines on the Screen (Vertical or Horizontal)

Problem Description:
Thin or thick lines appear across the screen, affecting viewing.

Technical Causes:

• T-Con Board Malfunction: This board synchronizes display signals.
• Loose Ribbon Cables: Ribbon connectors between the panel and T-Con can cause intermittent lines.
• Damaged Display Panel: Physical impact or manufacturing defects may cause permanent lines.

Solutions by Refitec:

• We reseat ribbon cables to ensure proper contact.
• If T-Con is faulty, we replace it from our stock.
• For panel damage, we provide panel replacement services where parts are available.

Maintenance Tips:

• Avoid pressing or touching the screen surface.
• Ensure your TV is mounted securely to avoid accidental damage.

5. Remote Control Not Working

Problem Description:
The TV is fine, but the remote fails to respond.

Technical Causes:

• Depleted Batteries (most common).
• Blocked IR Sensor: Dust or obstructions prevent signals from reaching the TV.
• Faulty Remote IC: When the chip inside fails, it stops transmitting.

Solutions by Refitec:

• We test with a replacement remote to confirm if the problem is with the remote or TV sensor.
• If the remote is damaged, we supply original replacements for all brands.
• TV IR sensor issues are repaired or replaced.

Maintenance Tips:

• Change batteries at the first sign of weak response.
• Keep the IR sensor clean and unobstructed.

6. Smart TV Connectivity Issues (Wi-Fi / Apps Not Working)

Problem Description:
Smart TVs fail to connect to Wi-Fi or apps like Netflix, YouTube, and Showmax freeze or crash.

Technical Causes:

• Corrupt Firmware: Outdated software disrupts connectivity.
• Wi-Fi Module Failure: The internal Wi-Fi chip may fail.
• Router Compatibility Issues: Sometimes, the problem is not the TV but the router.

Solutions by Refitec:

• We perform firmware upgrades to restore stability.
• If the Wi-Fi module is damaged, we replace it with a compatible spare.
• Router settings are checked for compatibility with the TV’s network standards.

Maintenance Tips:

• Regularly update your Smart TV software.
• Use a stable internet connection with strong bandwidth.

7. Overheating and Automatic Shutdown

Problem Description:
The TV switches off on its own after a few minutes of operation.

Technical Causes:

• Blocked Ventilation: Dust accumulation restricts airflow.
• Faulty Cooling Fans (in some models): Fans fail due to dust or damage.
• Mainboard Overheating: Overloaded circuits shut down to protect components.

Solutions by Refitec:

• We clean internal dust using specialized electronic blowers.
• Faulty fans are replaced.
• Thermal paste is reapplied to overheating chips for cooling efficiency.

Maintenance Tips:

• Place your TV in a well-ventilated area.
• Schedule regular servicing to keep components dust-free.
