Certified technicians dispatched to you — same day.
Resistors are passive components that limit or regulate electrical current flow within a circuit. In television electronics, they appear throughout the power supply, audio amplifier, and signal processing sections of the board. While individual resistors are extremely reliable and rarely fail on their own, they can burn open or change value when subjected to overcurrent conditions — usually following a more catastrophic failure event such as a power surge. Identifying a failed resistor requires a multimeter and some electronics knowledge.
Where to buy in Nairobi: Resistors are widely available at Nerokas, Ktechnics, Universal Tech Electronics, and component stalls in River Road and Kirinyaga Road markets. They are sold per piece or in assorted packs.
| Resistor Type | Power Rating | Estimated Price (per unit / per pack) |
|---|---|---|
| Carbon film resistor (1/4 W) | 0.25 W | KSh 5 – 15 per piece |
| Metal film resistor (1/4 W, 1% tolerance) | 0.25 W | KSh 10 – 30 per piece |
| Carbon film (1/2 W) | 0.5 W | KSh 10 – 25 per piece |
| Wirewound resistor (power) | 2 W – 10 W | KSh 30 – 150 per piece |
| SMD resistor (0805, pack of 10) | 0.125 W | KSh 20 – 80 per pack |
| Assorted resistor kit (100–500 pcs) | Various | KSh 300 – 1,200 |
Note: Resistors are among the cheapest electronic components available in Nairobi. The cost of resistor repair is dominated entirely by the technician's diagnostic and labour time rather than the component price.
