Common TV Problems and Solutions

Below, we’ll explore the most frequent TV issues, explain their underlying causes, provide technical troubleshooting breakdowns, and outline long-lasting solutions.

1. TV Not Powering On

Symptoms:

• TV shows no light or sign of life.
• Power indicator remains off even when plugged in.
• Clicking sound but no startup.

Technical Explanation:
This usually points to issues in the power supply board (PSU), where key components like capacitors, fuses, or rectifiers may have failed. In many cases, Kenyan homes along Lang’ata Road experience power surges and outages, which can stress these delicate components.

Diagram-Style Breakdown:

• AC Power Input → Fuse → Rectifier → Filter Capacitors → Voltage Regulators → Mainboard
  Any break in this chain causes a dead TV.

Solution:

• Test the fuse for continuity.
• Inspect for bulged or leaking capacitors.
• Replace faulty rectifiers or regulators.
• If beyond repair, a power board replacement is recommended.

✅ At Refitec, we stock original power boards for brands like Samsung, LG, Sony, Hisense, TCL, Skyworth, Panasonic, and Sharp.

Maintenance Tip: Use a quality surge protector along Lang’ata Road, where power instability is common.

2. No Picture but Sound Works

Symptoms:

• Screen is black but audio is clear.
• Flashlight test reveals faint images (backlight issue).

Technical Explanation:
This is often linked to backlight failure or issues with the T-Con (Timing Control) board. LED strips may burn out due to overheating, while voltage irregularities can fry the T-Con.

Diagram Breakdown:

• Mainboard → T-Con Board → LED Driver → LED Strips (Backlight)

Solution:

• Test LED strips individually.
• Replace burnt-out strips with high-efficiency LED bars.
• If no improvement, swap the T-Con board.

✅ We have backlight strips and T-Con boards in stock for fast replacements.

Maintenance Tip: Reduce screen brightness in settings—this prolongs LED strip life.

3. Distorted or Noisy Picture

Symptoms:

• Color patches on screen.
• Horizontal/vertical lines.
• Ghosting or flickering images.

Technical Explanation:

• Faulty T-Con board → causes vertical/horizontal lines.
• Loose LVDS cable → ghosting.
• Damaged screen panel → discoloration.

Solution:

• Reseat LVDS ribbon cable.
• Replace faulty T-Con board.
• In extreme cases, a panel replacement may be needed (Refitec can source compatible panels).

4. TV Has Sound but No Picture

This issue, while similar to backlight failure, sometimes involves:

• Mainboard malfunctions.
• Faulty video processors.
• Corrupted firmware.

Solution:

• Test video signal path from mainboard.
• Perform a firmware update or reflash.
• Replace the mainboard if hardware-level failure is confirmed.

✅ Refitec supplies mainboards for LG, Sony, Samsung, Hisense, TCL, and more.

5. TV Turns On Then Off Immediately (Boot Loop)

Symptoms:

• TV powers up, logo appears, then shuts off.
• Continuous restart loop.

Technical Explanation:

• Overheating IC chips.
• Corrupted software.
• Defective capacitors in the power board.

Solution:

• Update firmware via USB.
• Replace overheating IC chips.
• Swap power board if voltage instability persists.

6. Remote Not Working or TV Not Responding

Causes:

• Remote’s IR sensor failure.
• Faulty TV IR receiver module.
• Mainboard not processing remote commands.

Solution:

• Test with a universal remote.
• Replace TV’s IR receiver module.
• Check mainboard response via oscilloscope.

7. HDMI/USB Ports Not Working

Causes:
