Common TV Problems We Repair

Below are the common TV problems we regularly encounter in Gigiri homes and offices; for each we provide technical insight, step-by-step diagnostic approach, and clear solutions plus maintenance tips.

1. Screen Flickering, Lines, or Black/White Patches

Description of the Problem:
You switch on the TV and see horizontal or vertical lines, flickering edges, occasional black or white patches, or parts of the screen going blank. Sometimes whole areas of the screen are discoloured; other times the flickering is intermittent.

Technical Breakdown

• LCD / LED Panel Issues: The actual panel may have dead rows/columns. The TFT matrix driver may be failing.
• T-Con Board Failure: The timing control (T-Con) board is crucial—responsible for translating the video signal into row/column driving voltages. If capacitors or ICs on T-Con board are failing, you’ll see flicker or partial display.
• Flex Ribbon or LVDS Cable Problems: The cable connecting the T-Con to the panel (flex ribbon or LVDS cable) might be loose, crimped or damaged; intermittent connections lead to lines or missing sections.
• Backlight / Inverter Issues: In LED and LCD backlit TVs, the backlight LEDs or the inverter (for CCFL backlights in older units) may flicker or fail, causing patches of black or dimness.

Solutions We Provide

• Panel Replacement or Repair: If the panel matrix is too damaged (e.g. large dead zones), we replace it with original or matching model spares.
• T-Con Board Repair or Swap: Use tested T-Con boards; repair faulty capacitors or ICs, or swap with compatible boards.
• Cable Re-seating and Replacement: Check connectors (LVDS connector), clean contact points, replace flex ribbons if frayed or torn.
• Backlight / Inverter Board Fixes: Replace failing LEDs or CCFL tubes; repair or swap inverters and driver circuits.

Maintenance Tips

• Avoid leaving static images for long periods (prevents burn-in or stuck pixels).
• Keep the TV in well ventilated space; heat accelerates failure of boards and connectors.
• Use surge protectors especially in areas prone to power fluctuations (Kiambu Road, Limuru Road sections).
• Clean vents regularly; dust accumulation causes overheating of T-Con and power supply boards.

2. TV Won’t Turn On / Power-Related Failures

Description:
Press the power button, LED indicator doesn’t light up; maybe clicks, then nothing; or TV cycles on and off; sometimes the power light glows but no picture.

Technical Breakdown

• Power Supply (PSU) Board Faults: The PSU board converts AC mains (e.g. 110-240V) to low-voltage DC rails used by other subsystems. Components like main switch‐mode regulators, large filter capacitors, fuses, and transformers may fail.
• Standby Circuit Malfunction: The standby circuit keeps minimal current for remote control / IR receiver, and if it’s broken, no signal to wake up the TV.
• Overcurrent or Protection Mode Triggered: If short circuits or overcurrent occur (e.g. from panel short or PSU overload), the protection circuits may shut down the TV.
• Firmware or Softpower Button Issues: Sometimes software or firmware prevents full boot, or buttons/IR remote sensor are defective.

Solutions Offered

• Diagnostics on PSU Board: Use multimeter to check presence of critical rails (+5V, +12V, ±15V etc.), replace bulging capacitors, burnt resistors, blown fuses.
• Replace Standby ICs or Related Components: If standby IC is dead, swap with matching IC; repair IR sensor or remote module.
• Isolation of Short Circuits: Disconnect suspect modules (e.g. speakers, backlight LED arrays) to see where overload occurs; replace faulty parts.
• Firmware Reset / Button Repair: If TV has USB or network update option, re-flash firmware; fix or bypass broken power buttons or sensors.

Maintenance Tips

• Always shut down properly; avoid leaving on standby for long times.
• Use voltage stabilisers in areas like Village Market or Ridgeways where power spikes/drops are common.
• Check AC cable condition; frayed or exposed wires increase risk of shorts.
• Unplug during storms to avoid damage from lightning or surges.

3. No Audio / Distorted Sound / Speaker Issues

Description:
Picture is fine, but no sound; audio is muffled or distorted; static, buzzing, or crackling; sometimes one side (left/right) works, the other doesn’t.

Technical Breakdown

• Audio Amplifier Board or IC Failure: The audio amplifier chip or transistor stage may have burnt components, shorted traces, or thermal damage.
• Speaker Damage: Speakers inside the TV — if cones are torn, voice coils burnt, or magnets misaligned, sound will distort or drop.
• Signal Path Problems: From tuner / HDMI / AV input => audio decoding IC => amplifier => speaker. If any part is missing signal (e.g. bad input jack), sound fails.
• Crosstalk or Interference: Electric noise from power supply or cable interference can get into audio paths causing buzzing or humming.

Solutions Provided

• Repair or Replace Audio Board: Replace defective amplifier ICs, clean or replace capacitors, check resistors and thermal protection circuits.
• Speaker Replacement / Repair: Use matching speaker units; rewire properly; ensure correct impedance.
• Fix Input Connectors & Signal Routing: Change faulty jacks (HDMI, AV, coax); re-solder loose solder joints.
• Shielding and Grounding: Add or restore good grounding; shield cables; filter out noise via capacitors or ferrite beads.

Maintenance Tips

• Don’t play audio at maximum volume continuously (prevents overheat of speaker coil).
• Keep humidity low; moisture warps speaker diaphragms.
• Check connector plugs and keep them clean, not loose.
• If using external speakers or soundbars, ensure correct impedance match to avoid strain.

4. Signal / Reception Problems: Poor Picture, Static, Lost Channels

Description:
Channels drop out; picture has static or mosaic; signal says “No Signal”; satellite or cable reception weak; WiFi smart TV streaming laggy or buffering.

Technical Breakdown

• Tuner / Demodulator Component Issues: The internal tuner (or external box) may be failing; demodulation circuits that interpret RF/coax input might be weak.
• Loose or Damaged Cables / Connectors: Coaxial or HDMI cables may be old, corroded, poorly shielded.
• Antenna / Satellite Dish Alignment or Dish LNB Problems: LNB (for dish) degrade; dish may shift; antenna may need repositioning.
• Interference from Other Devices: Nearby electronics, high-power motors, or bad power supplies may inject noise.
• Smart / Streaming Apps Buffering: Weak WiFi, outdated firmware or overloaded processors inside TV.

Solutions We Provide

• Replace or Calibrate Tuner / Demodulator ICs: Test tuner board; replace faulty chips.
• High-Quality Cable Replacement: Use well-shielded HDMI/coax; ensure connectors are tight; use F-type connectors with good quality.
• Dish & Antenna Maintenance: Realign dish; replace worn-out LNB; clean rust, ensure grounding.
• Filter Interference & Update Firmware: Add ferrite cores to power cables, maintain separation of signal and power lines; ensure TV firmware is up to date; upgrade WiFi antennas or modules if possible.

Maintenance Tips

• Check outdoor dishes & antennas after heavy winds or rain.
• Clean connectors every few months; avoid water ingress.
• Upgrade your internet/WiFi router if streaming often.
• Use signal boosters or amplifiers in long cable runs inside the house (e.g. in Runda’s larger houses).

5. Overheating & Internal Component Failure

Description:
TV feels very hot, performance lags, sudden shutdowns, weird smells, burn-in of screen, image retention.

Technical Breakdown

• Poor Thermal Management: Heat sinks, ventilation grills may be blocked; fans (if present) may fail.
• Failing Heat Sink Paste / Mounts: On processor / main ICs, the thermal interface material (TIM) dries out, reducing efficient heat transfer.
• Low Quality or Aging Components: Capacitors degrade; resistors drift; ICs develop micro-cracks under heat stress.
• Power Supply Overload: If PSU working too hard because of bad cooling, its parts overheat and fail.

Solutions Provided

• Clean Vents & Fan Systems: Dust out heat sinks, blow compressed air through grills.
• Replace Thermal Paste and Re-mount Heat Sinks: Use high quality thermal compound; ensure even contact.
• Upgrade / Replace Aging Components: Use long-life capacitors (electrolytic caps with high temperature rating, e.g. 105°C) instead of generic ones.
• Check Ambient Conditions: Ensure TV is not sun-facing; keep room moderately cool; allow breathing space around sides.

Maintenance Tips

• Avoid placing TV directly beneath or in front of windows with intense sun exposure or glass walls (common in New Gigiri villas).
• Keep at least a few inches (or cms) clearance behind, above, below the TV.
• Dust the vents every few weeks; once per year have full internal clean / preventive service.
• Use surge protector and voltage stabiliser especially in power fluctuations common around Muthaiga Road, Limuru Road, Jogoo Road junctions.

6. Remote Control, Buttons, and Software / Firmware Glitches

Description:
TV does not respond to remote; buttons unresponsive; software menus frozen; apps crash; smart features lag.

Technical Breakdown

• IR Sensor / Input Board Problems: The IR receiver or the board that processes button inputs may be faulty.
• Mechanical Button Wear: On-screen buttons or side buttons may have worn switches, contact points dirty or oxidised.
• Firmware Bugs or Corrupted Software: Smart TV OS or built-in apps may have bugs; storage (flash memory) issues.
• Insufficient Memory / Processor Overload: Too many background apps; lack of memory for updates or caching.

Solutions Offered

• Replace IR / Input Board or Repair Connections: Swap in correct module; reflow solder joints; clean connectors.
• Repair Mechanical Buttons: Clean or replace worn out switch contacts; ensure proper tension and feedback.
• Re-Flash Firmware / Update Software: Load latest firmware; sometimes revert to factory settings; clear cache.
• Upgrade Storage or Reboot/Reset Periodically: Remove unused apps; ensure enough free memory; power cycle regularly.

Maintenance Tips

• Keep firmware up to date; set auto-update if available.
• Don’t overload TV with unneeded apps / excessive streaming in background.

• When power fails, we test PSU voltages.
• If image fails but sound works, often T-Con or panel issue.
• If flickering or lines, likely the connection between T-Con and panel (e.g. LVDS cable) or T-Con board ICs.
• Audio failure with picture OK typically isolates to audio amplifier or speaker module.

Maintenance & Preventive Care: Keep Your TV Running Longer

To reduce frequency of repair and extend lifespan:

1. Surge Protection & Voltage Regulation
   Invest in a good voltage stabilizer / surge suppressor. Nairobi can have fluctuating power especially in Gigiri near Kiambu Road, Limuru Road. This protects PSU and related circuitry.
2. Ventilation & Positioning
   Make sure the TV is not enclosed tightly. Vents on the top and bottom need airflow. Avoid direct sunlight or heat sources (lamps, windows). Leave at least ~10–15 cm of space behind and on sides.
3. Clean Dust & Moisture
   Dust acts as insulation, traps heat, causes hot spots. Moisture leads to corrosion. Clean vents and back with soft brush/compressed air. In rainy seasons, keep humidity controlled.
4. Regular Firmware Updates
   For smart/connected TVs, check manufacturer updates. These often fix bugs, optimize performance, reduce memory leaks that can cause crashes or lag.
5. Moderate Usage
   Do not leave static images (e.g. logos) continuously for many hours; avoid very high brightness settings often. This helps prevent image retention and panel stress.
6. Handle Cables Properly
   Insert/remove HDMI/coax/plugs carefully. Avoid bending or twisting cables. Use good quality shielded cables. Keep away from power cables to reduce interference.
