Introduction: Reliable TV Repair in Luanda Town

Luanda Town in Vihiga County is one of the busiest urban centers in Western Kenya. With estates like Mwibona, Esibuye, Ebusiratsi, and numerous feeder roads, homes and businesses here rely heavily on televisions for entertainment, news, education, and sports.

In this detailed guide, we’ll break down the most common TV problems in Luanda, explain their causes, give technical insights, provide professional solutions, and offer maintenance tips to help extend your TV’s lifespan.

1. TV Screen Problems – Cracks, Lines, and Display Failures

Technical Breakdown

The TV screen is the most delicate and expensive component. Issues include:

• Cracked Screens – often caused by accidental falls or impact.
• Vertical/Horizontal Lines – caused by loose ribbon cables, faulty T-con boards, or damaged LCD layers.
• No Display but Sound Works – typically linked to a dead LED backlight or faulty inverter board.
• Color Distortion – when pixels degrade due to heat or internal damage.

Diagram-style explanation:

TV Screen Assembly:
[Outer Glass] → [Polarizer Layer] → [LCD/LED Panel] → [Backlight] → [T-Con Board]

A crack usually damages the LCD layer, while display lines come from issues in the T-Con board or ribbon connections.

Solutions

• Cracked Screens – require full screen replacement.
• Display Lines – reseating or replacing the T-Con board and ribbon cables.
• Backlight Failure – replace LED strips or inverter boards.
• Color Distortion – panel replacement if severe.

Spare Parts Availability

Maintenance Tips

• Mount your TV on a stable wall bracket.

Technical Breakdown

The power supply board (PSU) regulates current to all TV components. Common issues include:
