Common TV Problems & Professional Solutions

1. TV Not Powering On

Symptoms:

• TV won’t turn on at all.
• Standby light is absent or keeps blinking.
• Clicking sound when trying to power on.

Technical Causes:

• Blown fuse in the power supply board.
• Faulty capacitors (bulging or leaking).
• Damaged mainboard ICs.
• Surge damage from unstable electricity.

Refitec Solution:
Our technicians perform multimeter and oscilloscope tests on the power supply board to isolate faults. If capacitors are swollen, we replace them with high-voltage equivalents. For surge-related IC damage, we desolder and install new ICs.

Maintenance Tip: Use a surge protector or voltage stabilizer to prevent future damage.

2. TV Has Sound But No Picture

Symptoms:

• Screen is black but audio works.
• Flashlight test reveals faint images.

Technical Causes:

• Backlight LED strip failure.
• Inverter board malfunction.
• T-Con board fault.

Refitec Solution:
We test the backlight circuit using LED testers. If strips are burnt, we replace them with matching brightness and voltage-rated LED bars. If the inverter is faulty, we replace or repair MOSFETs.

Maintenance Tip: Keep brightness settings moderate to extend backlight life.

3. TV Has Picture But No Sound

Symptoms:

• Clear image but completely silent.
• Volume controls don’t respond.

Technical Causes:

• Speaker driver IC failure.
• Loose speaker connections.
• Muted digital audio IC.

Refitec Solution:
We test speaker continuity, replace faulty speaker cones, and reflow or replace audio ICs. For smart TVs, firmware updates sometimes restore sound functions.

Maintenance Tip: Avoid playing TV at full volume, which stresses audio ICs.

4. TV Screen Flickering or Flashing

Symptoms:

• Screen flickers intermittently.
• Brightness fluctuates randomly.

Technical Causes:

• Loose LVDS (screen ribbon) cable.
• Power supply voltage instability.
• T-Con board capacitor failure.

Refitec Solution:
We reseat LVDS connectors, test power outputs, and replace defective capacitors. For OLED/QLED models, pixel refresh functions are reset.

Maintenance Tip: Keep your TV in a stable environment (avoid moisture and dust).

5. TV Remote Not Working / TV Not Responding

Symptoms:

• TV doesn’t respond to remote.
• Remote only works at close range.

Technical Causes:

• Faulty IR sensor in the TV.
• Remote IC or diode damage.
• Software glitches in smart TVs.

Refitec Solution:
We replace TV IR receivers, reprogram remotes, and perform factory resets for software-related failures.

Maintenance Tip: Keep remote and sensor area free from dust.

6. Lines on Screen (Vertical/Horizontal)

Symptoms:

• Thin or thick colored lines across screen.
• Image distortion.

Technical Causes:

• T-Con board or panel driver fault.
• Loose COF (Chip on Film) connections.
• Cracked LCD screen.

Refitec Solution:
We test T-Con boards using oscilloscope waveform analysis, reflow COF connections, or replace damaged panels when needed.

Maintenance Tip: Avoid pressing or tapping on the screen.

7. Smart TV Not Connecting to Wi-Fi

Symptoms:

• TV fails to detect wireless networks.
• Frequent disconnections.

Technical Causes:

• Faulty Wi-Fi module.
• Corrupt firmware.

Refitec Solution:
We replace Wi-Fi modules, update firmware, and configure network settings.

Maintenance Tip: Keep router close and update TV software regularly.

8. TV Overheating & Auto Shutdown

Symptoms:

• TV runs for a while then switches off.
• Back cover feels hot.

Technical Causes:

• Blocked ventilation.
• Dust accumulation in cooling system.
• Power board overheating.

Refitec Solution:
We clean internal cooling systems, reapply thermal paste on ICs, and add mini cooling fans if required.

Maintenance Tip: Place TV in a well-ventilated area.

9. Cracked or Broken TV Screen

Symptoms:

• Visible cracks.
• Dead pixels.
• Unresponsive touch (for smart displays).

Refitec Solution:
We replace TV panels with original manufacturer spare parts.

Maintenance Tip: Use wall mounts and keep TVs out of children’s reach.

10. HDMI / USB Ports Not Working

Symptoms:

• No signal on HDMI input.
• USB not detected.

Technical Causes:

• Damaged HDMI/USB ports due to frequent plugging.
