Tuner Board (RF Tuner)
Television Tuner Board: Estimated Prices in Nairobi for Different Sizes and Brands
The tuner board (also called the RF tuner or demodulator board) is the component responsible for receiving over-the-air broadcast signals — either analogue (in very old sets) or digital (DVB-T2 in Kenya's current broadcasting standard). It tunes into the transmitted frequency and decodes the signal into audio and video that the TV can display. In smart TVs, the tuner is typically integrated into the main board rather than being a separate module, but in older and mid-range sets it is a standalone replaceable board.
When does a tuner fail? Symptoms include inability to scan channels, poor signal quality even with a functioning aerial, or complete loss of broadcast reception while other inputs (HDMI, USB) work fine. Given Kenya's full transition to digital terrestrial television, DVB-T2 compatible tuners are the ones now in demand.
| Type | Estimated Tuner Board Price | Estimated Labour |
|---|---|---|
| DVB-T2 standalone tuner board | KSh 2,000 – 6,000 | KSh 1,000 – 2,500 |
| Integrated (brand-specific module) | KSh 4,000 – 10,000 | KSh 1,500 – 3,000 |
| External set-top box (alternative) | KSh 2,500 – 5,000 | — |
Note: In many cases, a faulty TV tuner is more economically replaced by pairing the TV with an affordable external DVB-T2 set-top box rather than sourcing a specific internal tuner board. This is often the faster and cheaper solution in Nairobi.
