Inverter Board (in Older LED/LCD Sets)
Television Inverter Board: Estimated Prices in Nairobi for Different Sizes and Brands
The inverter board was a critical component in older LCD televisions that used CCFL (Cold Cathode Fluorescent Lamp) backlights rather than LEDs. The inverter converted low DC voltage into the high-frequency AC voltage needed to power those fluorescent tubes. While modern LED TVs do not use inverter boards (they use LED driver boards instead), a large number of older LCD sets from 2008–2015 are still in use across Nairobi households and offices. For these sets, inverter boards remain a relevant spare part.
When does an inverter fail? Symptoms include a dim screen that improves when a torch is shone on it, flickering at startup, or a screen that turns off shortly after switching on. Prologic Technologies and other Luthuli Avenue shops often stock inverters for common older models.
| Screen Size / Model Era | Estimated Inverter Board Price | Estimated Labour |
|---|---|---|
| 32 inch CCFL (pre-2014) | KSh 2,000 – 5,000 | KSh 1,500 – 2,500 |
| 40–42 inch CCFL | KSh 3,000 – 7,000 | KSh 1,500 – 3,000 |
| 46–50 inch CCFL | KSh 4,500 – 9,000 | KSh 2,000 – 3,500 |
| Dual-lamp inverter boards | KSh 5,000 – 12,000 | KSh 2,000 – 4,000 |
Note: As the stock of old CCFL TVs shrinks, inverter boards for rare or obscure models may be difficult to find locally. Technicians may source them from online suppliers, with import lead times of 1–2 weeks.
