1. TV Screen Problems in Riat Hills Kisumu

One of the most common complaints we receive is screen-related issues. The display is the heart of your TV, and any damage or malfunction can make it completely unwatchable.

a) Cracked or Broken TV Screen

• Cause: Physical damage from falls, impact, or pressure.
• Explanation: The LED/LCD/OLED panel is made up of multiple layers – a glass substrate, liquid crystal or organic diode layers, and a polarizer. Any crack disrupts this alignment, causing dead pixels, lines, or black patches.
• Solution: TV screens cannot be repaired; the entire display panel must be replaced. At Refitec, we stock original screen panels for major TV brands.

Diagram-style breakdown:

• Top polarizer → damaged by cracks → leads to distorted visuals.
• Liquid crystal/organic layer → loses alignment → dead spots.
• Backlight → unaffected but cannot project correctly through broken layers.

b) Lines on the Screen (Vertical/Horizontal)

• Cause: Loose T-Con board connection, faulty screen ribbon cables, or damaged display drivers.
• Solution: We carefully reseat or replace ribbon cables, repair/replace T-Con boards, or, if the issue is panel-based, recommend screen replacement.

c) Dark Spots / Backlight Failure

• Cause: Burnt or damaged LED backlight strips.
• Solution: We replace faulty LED backlight strips with genuine parts.

2. TV Power Problems

a) TV Not Turning On

• Cause: Blown fuse, faulty power supply board, or surge damage.
• Technical breakdown:
  • AC power enters through the SMPS (Switched Mode Power Supply).
  • Converts to low voltage DC for mainboard and backlight.
  • A fault in capacitors, MOSFETs, or transformers prevents startup.
• Solution: Refitec technicians replace fuses, capacitors, MOSFETs, or entire PSU boards.

b) TV Turns On Then Off Immediately

• Cause: Protection mode triggered by short circuits on motherboard or backlight.
• Solution: Board-level diagnosis, short removal, or replacement of faulty ICs.

c) Red/Green Blinking Light (Standby Error)

• Cause: Error codes signaling motherboard or T-Con failure.
• Solution: We use service manuals and multimeter diagnostics to identify and replace defective chips.

3. TV Sound Problems

a) No Sound But Picture Works

• Cause: Faulty audio IC, blown capacitors in audio circuit, or software glitch.
• Solution: We re-solder or replace audio ICs, test speaker connections, and update firmware.

b) Distorted or Cracking Sound

• Cause: Faulty speakers or damaged amplifier IC.
• Solution: Replace speakers or amplifier circuits with original spare parts.

4. TV Motherboard & T-Con Issues

The motherboard is the brain of the TV. It processes video, audio, and smart features.

a) TV Stuck on Logo / Boot Loop

• Cause: Corrupt firmware or NAND memory failure.
• Solution: We flash new firmware using USB/JTAG programmers or replace NAND chips.

b) HDMI/USB Ports Not Working

• Cause: Physical damage to ports or failed controller IC.
• Solution: Replace ports or controller ICs.

c) T-Con Board Failures

• Cause: Overheating, power surges, or ribbon cable damage.
• Solution: Replace or repair T-Con board, ensuring correct voltage levels.

5. Smart TV & Software Problems

Modern smart TVs have Wi-Fi modules, operating systems, and app integrations.

a) TV Not Connecting to Wi-Fi

• Cause: Faulty Wi-Fi module, outdated firmware.
• Solution: Replace Wi-Fi module or update firmware.

b) Apps Crashing or Not Loading

• Cause: Low storage, corrupted OS.
• Solution: Reset TV, update OS, or replace eMMC storage.

6. TV Remote Control & Sensor Problems

• Cause: Dead IR receiver, blocked signal path.
• Solution: Replace IR sensors or remotes.
