Common TV Problems and Their Solutions

Let’s break down the most common issues we handle in Ngong Racecourse and surrounding estates.

1. TV Won’t Power On

Problem Explanation
When your TV refuses to power on, it could be a sign of issues in the power supply board, mainboard, fuse, or capacitors. The power board converts AC from the wall socket into the DC voltages required by your TV’s circuits. If this fails, the TV won’t even blink.

Technical Breakdown (Diagram Style)

• ⚡ AC Input → Fuse → Rectifier → Filter Capacitors → Voltage Regulator → Mainboard Power Distribution.
• If the fuse is blown → No power reaches the circuits.
• If the capacitors are swollen/leaking → Power instability.
• If the rectifier diodes fail → No conversion from AC to DC.

Solution
Our technicians test the power board using a multimeter to trace voltages. Depending on the diagnosis:

• Replace blown fuses.
• Replace swollen or leaking capacitors.
• Repair/replace faulty power boards.

We stock genuine spare parts like capacitors, fuses, and power boards for all major TV brands.

Maintenance Tip
Always use a surge protector to shield your TV from Nairobi’s unpredictable power surges.

2. No Picture but Sound is Working

Problem Explanation
If you can hear sound but the screen is black, it’s often an issue with the backlight system or T-Con board. Modern LED and LCD TVs use LED strips behind the screen to illuminate the image.

Technical Breakdown

• 🎛️ Mainboard → T-Con Board → LED Driver → Backlight LEDs.
• If the backlight strips burn out, the screen remains dark.
• If the T-Con board fails, data from the mainboard doesn’t reach the screen.

Solution

• Backlight replacement (we stock LED strips for Samsung, LG, Hisense, and Sony TVs).
• T-Con board replacement or repair.

Maintenance Tip
Avoid setting the brightness too high. High backlight intensity shortens LED lifespan.

3. TV Turns On Then Off Immediately (Power Cycling)

Problem Explanation
This problem usually comes from faulty capacitors, overheating, or mainboard firmware corruption.

Technical Breakdown

• 🔄 Power Board → Mainboard → Feedback Circuit → Protection Mode.
• If feedback detects unstable voltages, the TV shuts off automatically.
• Firmware corruption can cause endless restart loops.

Solution

• Replace faulty capacitors or ICs.
• Reflash or update the TV firmware.
• Improve cooling (fan/vent cleaning).

Maintenance Tip
Keep your TV well ventilated. Avoid placing it flush against the wall.

4. Lines on the Screen (Vertical or Horizontal)

Problem Explanation
Lines across the screen indicate panel failure, T-Con issues, or ribbon cable faults.

Technical Breakdown

• 📊 Mainboard → T-Con Board → LCD Panel via Ribbon Cables.
• If ribbon cables loosen, lines appear.
• If the panel itself fails (bad pixels), lines are permanent.

Solution

• Reseat ribbon cables.
• Replace T-Con board.
• Panel replacement (we source affordable panels for common models).

Maintenance Tip
Avoid pressing the screen or cleaning it with excess liquid—it damages panel layers.

5. No Sound but Picture Works

Problem Explanation
If your TV has a clear picture but no sound, possible causes include:

• Audio IC failure.
• Speaker damage.
• Software/audio setting errors.

Technical Breakdown

• 🎚️ Mainboard → Audio Processor IC → Amplifier → Speakers.
• If the IC fails → No audio output.
• If speakers blow → Distorted or no sound.

Solution

• Replace audio IC.
• Replace faulty speakers.
• Reconfigure software audio settings.

We stock original TV speakers and audio chips for replacement.

Maintenance Tip
Avoid playing TV at maximum volume constantly—this stresses the speakers.

6. Remote Control Not Working

Problem Explanation
Sometimes the TV is fine, but the remote control won’t respond. This may be due to:

• Dead batteries.
• Faulty IR sensor on TV.
• Remote PCB damage.

Solution

• Replace batteries.
• Clean/replace IR sensor.
• Replace or reprogram remote.

We have universal and brand-specific remotes in stock.

7. Smart TV Issues (Apps Crashing, No Internet, Freezing)

Problem Explanation
Modern Smart TVs often face software issues such as slow apps, Wi-Fi disconnection, or freezing screens.

Solution

• Perform firmware updates.
• Reset Smart Hub/Android OS.
• Replace faulty Wi-Fi modules.

Maintenance Tip
Regularly update your TV software to avoid security and performance issues.

Preventive Maintenance Tips for TVs

• Use a voltage stabilizer or surge protector.
• Keep your TV in a well-ventilated area.
• Dust the vents and back cover regularly.
• Avoid exposure to moisture.
