We also carry genuine spare parts, so you get lasting performance, not just a temporary fix.

Common TV Problems We Repair

We frequently address the following issues:

• No power / TV won’t turn on
• Screen issues: flickering, lines, dead pixels, image distortion
• Sound problems: no sound, distorted audio, no speaker output
• Board / circuit failures: main board, power supply board issues
• Connectivity issues: HDMI ports, USB, antenna/satellite inputs
• Overheating & cooling problems
• Firmware/software glitches

Each of these has underlying causes, and each requires specific technical know-how to resolve. Below: a deeper dive.

1. No Power / TV Won’t Turn On

What Happens & Technical Breakdown

When a TV won’t turn on, it could mean no response from the power button, no LED indicator, or a flicker and then shutdown. The typical culprits:

• Power supply board failure: either blown capacitors, bad voltage regulators, or a short circuit.
• Faulty input from mains power: loose plug, damaged power cord, or unreliable wall socket.
• Standby circuit malfunction: the front section that tells the TV to wake up is broken.
• Internal fuse blown.

Inside most LED, OLED, or LCD TVs, there is a power board which transforms AC mains voltage (110-240V depending on model) to multiple DC voltages (for example +5V, +12V, +24V, −12V etc.). These feed the logic board (main board), T-con board, backlight inverter, etc. If one of those outputs drops, the TV may not turn on.

Solution & Repair Steps

1. External power check: test wall socket with another device; inspect the power cord for cuts/fray.
2. Fuse checking: open back panel (after unplugging) and check internal fuse(es) for continuity with a multimeter.
3. Capacitor inspection: swollen or leaking capacitors on the power board need to be replaced.
4. Voltage rails test: measure DC outputs with multimeter to see if all required rails are present. If not, trace backward: perhaps voltage regulator or switching power supply module is bad.
5. Standby board repair: sometimes the standby controller or the microcontroller that listens for the remote or front-button press is dead; replacing or reprogramming may help.

We always use spare parts of high quality: replacement capacitors rated to correct voltage/temperature, replacement fuses, switching regulators, and compatible power supply boards.

Maintenance Tips

• Use a surge protector on the mains outlet, especially on Thika Road, near Kiambu Road, or Limuru Road where power spikes are common.
• Avoid pulling the power plug by the cord; always grip the plug.
• Keep ventilation open—never block fan vents or slots on the back of the TV.
• Unplug during storms to prevent lightning surges.

2. Screen Issues: Flickering, Lines, Dead Pixels, Image Distortion

Technical Breakdown

The screen side comprises layers: the backlight (in LCDs/LEDs), the liquid crystal or OLED emitters, the T-con (timing control) board, and the main board which sends video signal. Common components:

• Backlight LEDs or CCFL tubes (for older LCDs) that can dim or fail.
• T-con board which handles timing & row/column scanning; corrupted signals to the panel cause lines or strange color issues.
• Flexible flat cables (FFC) connecting T-con to panel. Loose or corroded connectors cause flicker or vertical/horizontal lines.
• Graphics or driver ICs (on the panel or on the board) might be damaged.

Common Problems and Their Causes

Solutions

• Backlight replacement: replace bad LEDs or LED strips; re-drive the backlight power supply; ensure matching color temperature.
• Reconnect or replace flat ribbon cables: clean connectors, reseat, replace if necessary.
• Replace T-con board or repair driver ICs: requires precise part sourcing; careful handling of fragile connectors; possibly reflowing solder if IC is marginal but repairable.
• Panel replacement (if most pixels are dead or significant physical damage). Panels are expensive; sometimes better to replace entire TV depending on model and cost.

Diagram-Style Explanation (Textual)

[ Main Board ] → video signal → [ T-con Board ] → timing lines → [ Panel / Pixel Matrix ]
                         ↘ power rails → Backlight driver → [ LED / CCFL backlight array ]

Each arrow corresponds to a pathway: signals, voltages. If any break, you get display problems.

Maintenance Tips

• Keep the panel clean; dust accumulation can increase heat which degrades FFC connectors and driver ICs.
• Avoid pressure on the screen; do not lean or press on it.
• Use the TV at moderate brightness; turning brightness too high increases stress on LEDs.
• If flickering begins, attend to it early; small connector issues are easier/cheaper to fix than replacing a whole panel.

3. Sound Problems: No Sound, Distortion, Speaker Failure

Technical Breakdown

Sound flows through:

1. Digital audio source (HDMI, tuner, smart TV OS) into audio decoder (on main board).
2. Audio amplifier stages (could be analog amplifier ICs or separate amplifier board).
3. Output to built-in speakers.

Issues often arise from:

• Faulty amplifier circuit: blown output transistors or ICs.
• Speaker cone damage: physical tear or wear.
• Bad coupling capacitors in audio circuits.
• Software / firmware muting or misconfiguration.

Common Problems & Causes

Solutions

• Check mute and volume settings; test with different inputs.
• Diagnose amplifier ICs: test for DC offset, check supply rails; replace failed amplifier chips.
• Replace coupling capacitors, especially if electrolytic ones are aged (bulging, leaking).
• Replace speaker units if physically damaged. Ensure impedance match (e.g., 8Ω, 4Ω).
• Update firmware if bug is software related (smart TVs).

Maintenance Tips

• Avoid playing sound at maximum volume constantly—it strains amplifier and speaker.
• Keep humidity low; moisture causes corrosion in speaker grills and connectors.
• Clean sound vents; ensure nothing blocks grills.

4. Board / Circuit Failures: Main Board, Power Supply Board, Inverter Board

Technical Breakdown

Your TV has several critical circuit boards:

• Power Supply Board (converts AC input to DC rails)
• Main Board / Logic Board (handles source input, video/audio decoding, control)
• T-con Board (timing control)
• Inverter Board (for CCFL backlights; or LED driver circuits for LED arrays)

Failures can be due to thermal stress, voltage spikes, manufacturing defects, aging capacitors, etc.

Specific Failure Scenarios

• Power supply component failure: MOSFETs, regulators, capacitors, input bridge rectifier can fail.
• Main board corruption: firmware corruption, failing ICs (like HDMI input chips, tuner chips).
• Inverter failure: in older LCDs, the inverter for CCFL or the LED driver fails, causing no backlight.

Solutions

• Trace voltage rails: measure from fuse onward through power supply to ensure correct voltages are present. Replace or reflow solder joints as needed.
• Replace or reflash firmware on main board. For branded TVs, some boards allow recovery from USB or firmware update.
• Replace failed ICs (if available as spare parts) or replace entire board if ICs are surface mounted and not repairable.

We keep in stock genuine spare boards or high-quality equivalent boards: power supply board, logic board, T-con board, LED driver board.

Maintenance Tips

• Keep TV in cool, ventilated spaces; avoid direct sun. Forest View Estate has hot midday sun near houses on Ridgeways Road, etc.
• Clean dust inside every 6-12 months; dust blocks airflow, raises internal temps.
• Ensure stable power supply; use voltage stabilizers if mains voltage fluctuates widely.

5. Connectivity Issues: HDMI, USB, Antenna, Satellite Inputs

Technical Breakdown

Modern TVs have multiple ports:

• HDMI / DisplayPort inputs
• USB (for media, firmware updates)
• Coaxial / RF input for antenna / cable / satellite
• ARC / eARC ports

Problems can occur from:

• Physical damage (bent pins)
• Corrosion / oxidation in connectors
• Software driver issues
• Broken internal traces or solder joints

Common Symptoms & Causes

Solutions

• Inspect and clean connectors: use isopropyl alcohol and air to remove dust/corrosion.
• Test with good quality cables.
• Repair or replace port: desoldering / re-soldering HDMI or USB port if damaged; replacing the entire port module if modular.
• Check internal signal paths: test continuity of traces, connectors to tuner or HDMI input chips.

Maintenance Tips

• Use high-quality shielded cables for HDMI / coax to reduce interference.
• Don’t force plugs in/out; align properly.
• Keep ports covered when not in use to avoid dust/dirt ingress.

6. Overheating & Cooling Problems

Technical Breakdown

Heat is the enemy of electronic components. Overheating causes:

• Expansion/contraction of solder joints (leading to cracked solder or micro-fractures)
• Degradation of electrolytic capacitors
• Thermal drift of ICs, leading to unstable operation

Common hot spots: power supply area, backlight inverter or LED driver, main processor chips.

Symptoms

• TV shuts off randomly after some time on.
• Fan noise (if any) increases, or fan fails.
• Burnt smell.
• Picture/sound distortion when TV is hot, returns to normal when cold.

Solutions

• Improve ventilation: ensure TV is not recessed in a tight cabinet without airflow.
• Clean dust from vents / fans.
• Replace failed cooling components: small fans or thermal pads, heat sinks.
• Check heat-dissipating paste or compound on processor chips; if dried, replace.

Maintenance Tips

• Leave space between back of TV and wall – at least few inches.
• Clean vents monthly using soft brush/vacuum.
• Operate in rooms without direct sun; avoid windows behind the TV when sun is intense. Forest View Estate homes on Ridgeways Road often have sun-exposed walls—shade or blinds help.

7. Firmware / Software Glitches

Technical Breakdown

Smart TVs rely on firmware (internal software), operating systems, and apps. Problems can arise from:

• Firmware bugs or outdated software
• Corrupted firmware due to interrupted update or power cut during update
• Bad apps or malware (less common)

Common Symptoms & Causes

• TV freezes / crashes / reboots
• Apps fail to launch
• Remote control not responding properly
• Network/WiFi connection drops

Solutions

• Check for firmware updates via manufacturer site or USB.
• Reinstall firmware: some TVs provide recovery mode.
• Factory reset if settings are corrupted.
• Clean up or disable unstable apps in smart platforms.

Maintenance Tips

• Always ensure stable power during firmware updates (use UPS if possible).
• Keep TV software updated.
• Avoid installing untrusted apps.
• Disconnect from internet when not using smart functions, to avoid unwanted background downloads or interference.
