Modern televisions have evolved dramatically over the past decade, with various display technologies dominating the market. Whether you own an LED, QLED, OLED, LCD, or plasma TV, understanding how these technologies work and their common repair issues can save you thousands of shillings in unnecessary replacements. This comprehensive guide explains LED, QLED, OLED, LCD and plasma television repair in detail, helping Kenyan consumers make informed decisions about fixing their TVs.
Understanding Different Television Technologies
Before diving into LED, QLED, OLED, LCD and plasma television repair, it’s essential to understand what makes each technology unique.
LCD (Liquid Crystal Display) TVs use liquid crystals sandwiched between glass panels with a backlight to create images. These are the foundation technology for most modern flat-screen TVs.
LED TVs are actually LCD TVs that use LED backlighting instead of older fluorescent tubes. This makes them more energy-efficient and slimmer than traditional LCDs.
QLED (Quantum Dot LED) TVs are Samsung’s premium LED TVs enhanced with quantum dot technology for improved color accuracy and brightness.
OLED (Organic LED) TVs use self-emitting organic pixels that don’t require backlighting, offering perfect blacks and exceptional contrast ratios.
Plasma TVs, though discontinued since 2014, are still in many Kenyan homes. They use ionized gas cells to create images and offer excellent picture quality.

Mainboard Issues: Logic board replacement for OLED TVs ranges from KES 18,000 to KES 35,000.
For OLED television repair, always consult authorized service centers first, as these TVs require specialized diagnostic equipment.
LCD Television Repair Essentials
Traditional LCD television repair remains common in Kenya, especially for older models with CCFL (fluorescent) backlighting.
CCFL Backlight Inverter Failure: The inverter powers the backlight tubes. Replacement costs KES 2,500 to KES 6,000.
Capacitor Replacement: Swollen or failed capacitors cause various issues. This affordable repair costs KES 1,500 to KES 4,000.
LCD Panel Issues: Pressure marks, dead pixels, or internal cracks require panel replacement, typically not cost-effective for older models.
Power Board Problems: LCD TV power supply repairs cost KES 3,000 to KES 7,000.
LCD television repair is generally more affordable than newer technologies, making it worthwhile to repair older LCD models.
Plasma Television Repair: Is It Worth It?
Plasma television repair is becoming increasingly difficult as parts availability dwindles, but many Kenyans still own these excellent displays.
Y-Sustain or X-Sustain Board Failure: These boards control the plasma cells. Repairs cost KES 8,000 to KES 18,000 when parts are available.
Power Supply Issues: Plasma TVs consume more power and stress power supplies. Replacement costs KES 6,000 to KES 12,000.
Capacitor Replacement: A common and affordable fix at KES 2,000 to KES 5,000.
Panel Degradation: Natural dimming over time isn’t repairable. Plasma panels are no longer manufactured.
Given the age of most plasma TVs and parts scarcity, plasma television repair should only be pursued if repair costs stay under 30% of a replacement TV’s price.
