Mini-LED backlights outperform full-array LED in contrast and dimming precision but cost 2–3x more to repair in Nairobi due to complex driver boards and denser LED arrays.

Key Technology Differences

Full-Array LED uses 100–300 larger LEDs (300–1000μm) spaced across the panel’s rear, enabling 16–100 local dimming zones. It delivers solid contrast (3000–5000:1) at lower cost, common in mid-range Hisense/TCL 43–65″ TVs.

Mini-LED packs 1000–10,000+ tiny LEDs (100–200μm) for 500–2000+ zones, slashing blooming around bright objects. Peak brightness hits 2000+ nits vs. full-array’s 1000–1500, ideal for HDR in Samsung Neo QLED or TCL C-series.

Feature	Full-Array LED	Mini-LED
LED Count	100–500	1000–10,000+
Dimming Zones	16–100	500–2000+
Contrast	Good (no heavy blooming)	Excellent (near-OLED blacks)
Brightness	1000–1500 nits	1500–3000+ nits
Power Use	Higher (100–300W)	Lower efficiency (80–250W)
TV Price	KES 25k–50k	KES 60k–150k

Mini-LED runs cooler (<50°C) but demands advanced heat sinks; full-array hits 60–70°C easier.

This comparison shows full-array’s spaced LEDs vs. Mini-LED’s dense grid—more zones mean precise dark area control.

Repair Cost Comparison (Nairobi 2026)

Full-Array Repairs: Simpler—strip swaps dominate (KES 4,000–12,000 for 43–65″). Driver boards add KES 2,500; parts abundant at Luthuli Avenue.

Mini-LED Repairs: Complex zoning requires board-level fixes. Driver ICs, MOSFETs fail from surges; full boards scarce.

Size	Full-Array Repair (KES)	Mini-LED Repair (KES)	Notes
43–55″	4,500–10,000	10,000–20,000	Mini: Samsung QA55QN90C board KES 12k
65″	9,000–15,000	18,000–30,000	TCL C735 zone mapping critical
75″+	14,000–22,000	25,000–45,000	Rare parts; 1–2 week wait

Labor: Full-array 1–2 hours (KES 2,000); Mini-LED 3–5 hours (KES 4,000–6,000) for firmware/thermal paste.

Repair Complexity Factors

Full-Array: Strip-focused; 80% cases = LED burnout. Tools: basic multimeter, thermal tape. 90% same-day Nairobi.

Mini-LED:

Driver Board Failures: PWM signals overload ICs (KES 8,000+).
Zone Mapping: Firmware mismatches cause patchy dimming.
Micro-Soldering: 0.2mm LEDs need hot air stations.
Parts Scarcity: Samsung PBAF3 boards imported; 20% pricier.

Failure Rates: Mini-LED drivers fail 25% faster from heat/voltage stress despite longer LED life (60,000+ hours).

When to Repair Each

Full-Array: Always viable <KES 12,000 (50% new TV cost). Hisense/Vitron strips KES 3,000 stocked.

Mini-LED: Repair if <5 years old and quote <KES 20,000 (65″ threshold). Beyond = new TV territory.

Nairobi Reality: TVrepairkenya.com stocks full-array universally; Mini-LED boards 2–7 day lead. Stabilizers prevent 30% recurrences both types.

Full-array offers budget repairs with good results; Mini-LED justifies premium fix costs for cinema-grade picture if parts available.
