Common TV Problems We Repair

Here are some of the frequent issues TV owners in Uthiru bring to us:

  1. No Power / Dead Set (TV won’t turn on)
  2. No Picture / Blank Screen / Flickering
  3. Distorted or No Sound
  4. Lines, Spots or Discoloration on Screen
  5. Smart TV Software Issues / Connectivity Problems

1. No Power / Dead Set

What Happens

Your TV has no response: no lights, nothing on screen when you press power. Sometimes the standby LED doesn’t even come on.

Technical Causes

  • Faulty power supply board (PSU): The PSU converts mains AC into required DC voltages for other boards. If one of its components—like capacitors, switching transistors (MOSFETs or transistors), bridge rectifier, regulator IC—is damaged, the TV won’t get power.
  • Blown fuse or surge damage: Sudden voltage spikes (from faulty mains, lightning, etc.) may blow internal fuses or damage input circuits.
  • Bad main board / control IC: After power supply, the main board distributes power. If it’s dead, no signal flows.
  • Power socket, cable or plug issue: Sometimes external causes: loose plug, worn cord, unstable socket.

Solutions

  • Diagnose the power board: Technicians open the back, inspect PSU capacitors (look for bulging or leaking), measure voltages with a multimeter. In many TVs, rails like +5 V, +12 V, ±24 V etc. must be present.
  • Replace faulty components: Bad capacitors, burnt resistors, diodes etc. If PSU board too damaged, replace with a spare part. We stock compatible power supply boards for many brands: Samsung, LG, Sony, Hisense etc.
  • Repair external wiring or sockets if that is the culprit.
  • Surge protection installation: Advice to plug TV into a good stabilizer or surge protector to prevent future damage.

Technical Breakdown / Diagram-Style Explanation

[ Mains AC ] → [ Fuse / EMI filter ] → [ Bridge Rectifier ] → [ Large Capacitors (smoothing) ] → [ Switching Regulators / DC-DC converters ] 
     ↓                                     ↓                                ↓
   Full wave                            Bulk capacitance              Voltage rails → Main board, T-Con board, Audio board

If any stage fails, downstream boards get no power → TV dead.


2. No Picture / Blank Screen / Flickering

What Happens

TV turns on; maybe you see sound, maybe even LED light; but screen is black or blank, or flickers – sometimes intermittently, sometimes constantly.

Technical Causes

  • Backlight failure (for LCD / LED TVs): The backlight LEDs or CCFL tubes are dead or driving circuits (inverter or LED driver) have failed.
  • T-Con board issues: T-Con (Timing Controller) controls the panel scan, timing of rows/columns. If its flex cables are damaged or connectors loose, picture can be blank or flicker.
  • Panel failure: The LCD / LED panel itself may have open circuits, shorted transistors, dead pixel areas.
  • Main board / HDMI source failure: Sometimes input source doesn’t feed video signal properly; wrong resolution, wrong HDMI port etc.
  • Voltage ripple / unstable power: PSU delivering unstable or fluctuating voltage causes flicker.

Solutions

  • Check backlight and driver circuits: Use a flashlight to see if faint image exists—if yes, backlight is gone. Replace backlight LEDs or driver board accordingly.
  • Replace or reseat T-Con boards / ribbons: Inspect the flat ribbon cable, look for damage, reseat connectors. Use compatible spare T-Con.
  • Panel replacement (if necessary): If entire panel is damaged—expensive, but sometimes economical for large TVs. We stock some panels and can source others.
  • Ensure stable power supply: Check PSU rails for ripple with an oscilloscope; replace capacitors; ensure power supply stability.
  • Update firmware or check inputs: For smart TVs, sometimes firmware bugs cause blank screen on startup; update via USB if accessible.

3. Distorted or No Sound

What Happens

Picture looks okay, but sound is bad: muffled, crackling, no audio, hissing, or intermittent.

Technical Causes

  • Faulty audio amplifier circuit: This is usually on a separate audio board or part of main board; components like amplifier ICs, capacitors, resistors may go bad.
  • Speakers damaged: Cone damage, loose connections, burnt coils.
  • Volume control / remote issues: If remote or internal volume circuitry fails.
  • Signal processing ICs / firmware: Bad firmware or codec errors in smart TVs cause no/strange audio.
  • Interference / ground loop / buzzing from power lines.

Solutions

  • Test speakers individually: Disconnect internal speakers and test using external speaker to isolate whether problem is in speakers or audio path.
  • Replace/tune audio amplifier components: Replace defective ICs, ensure capacitors coupling audio are good, clean potentiometers.
  • Check and replace faulty wires & connectors.
  • Update or re-flash firmware on smart TVs if audio processing bug.
  • Shielding and proper grounding. Install surge protection; avoid plugging too many devices into same socket, minimize interference.

4. Lines, Spots or Discoloration on Screen

What Happens

You see vertical/horizontal lines, color distortions, dark or bright spots, patches of screen with wrong hue.

Technical Causes

  • Damaged pixels / sub-pixel failure: In LCD / LED panels, individual pixels or sub-pixels may fail.
  • Loose or damaged flex ribbon cables: Between panel and T-Con board or between main board and T-Con; sometimes get worn, bent.
  • T-Con board failure / timing issues: Timing mismatches cause line artifacts.
  • Backlight irregularities (for spots): LED clustering problems or LED driver non-uniformity.
  • Burn-in (esp. in plasma or OLED types) or image retention.

Solutions

  • Ribbon cable reseating / replacing: Open TV, check cable connectors under microscope or magnifier, clean contacts, replace if corroded.
  • T-Con board replacement: We keep spare T-Con boards for many common TV brands to swap in.
  • Partial panel repair: Spots sometimes salvageable if due to backlight or driver issues; but full panel replacement if many defects.
  • Burn-in mitigation: For plasma / OLED, show full-screen bright colors, run pixel refresh, avoid static images.

5. Smart TV Software & Connectivity Issues

What Happens

Apps crash, WiFi won’t connect, HDMI devices not recognized, remote control doesn’t work, system freezes, Netflix or YouTube app misbehaves.

Technical Causes

  • Outdated or corrupt firmware/software: Smart OS needs updates; bugs can accumulate.
  • Memory/storage issues: Insufficient space for updates, or flash memory corruption.
  • Networking module problems: WiFi module or Ethernet port faulty.
  • HDMI port or board damage: Physical damage, wear, or solder joint failure.
  • Remote sensor / IR receiver issues.

Solutions

  • Firmware updates: Download latest firmware from manufacturer site; install via USB or over-the-air. For brands like Samsung Tizen, LG WebOS, Hisense, etc.
  • Factory reset & storage cleanup: Delete unused apps, clear cache; sometimes re-partition or re-flash storage.
  • Replace WiFi / LAN boards or modules: We have spare network boards / WiFi modules for many models.
  • Repair or replace HDMI ports / connectors.
  • Test remote sensors, replace IR receiver if faulty.

Maintenance Tips: Keeping Your TV Healthy

To reduce repairs and extend lifespan:

  • Stable power supply: Use a good voltage stabilizer or surge protector. Nairobi/Uthiru area has occasional power surges; protecting your TV’s PSU saves many parts.
  • Proper ventilation: Don’t enclose the TV in tightly sealed cupboards. Heat is enemy of electronics—ensure gaps for airflow, clean dust from vents periodically.
  • Regular dusting & cleaning: Dust insulates components, leading to overheating. Use soft cloth; avoid moisture; clean from back and side vents. For the screen, use suitable cleaning solutions.
  • Mind display usage habits: Reduce screen static content (news ticker, channel logos) to prevent burn-in; reduce brightness if your room is dark; use power-saving modes.
  • Avoid frequent power on/off cycles: Each time you power on, components—especially backlight LEDs—inrush current. Waiting a few seconds before turning back on helps.
  • Update software when prompted: Manufacturer updates often patch bugs, improve performance, fix security issues in smart TVs.
