Power Supply Board (SMPS)
Television Power Supply Board: Estimated Prices in Nairobi for Different Sizes and Brands
The power supply board (also known as the SMPS — Switched-Mode Power Supply) converts mains alternating current (AC) from the wall socket into the various direct current (DC) voltages needed by the TV's internal components. It is the component most commonly damaged by unstable electricity — a frequent challenge in many parts of Nairobi. Symptoms of a bad power supply board include the TV failing to turn on, a blinking standby light, random shut-offs, or a clicking sound on startup.
Good news for consumers: Power supply boards are among the more standardised TV components. Compatible replacements are often available even for older or less common models. Capacitor bulging on the PSU board is a tell-tale sign of failure that technicians can often spot visually.
| Brand / Screen Size | Estimated PSU Board Price | Estimated Labour |
|---|---|---|
| 32 inch (any brand) | KSh 3,500 – 7,000 | KSh 1,500 – 2,500 |
| 43 inch (any brand) | KSh 5,000 – 10,000 | KSh 1,500 – 3,000 |
| 55 inch (any brand) | KSh 6,000 – 13,000 | KSh 2,000 – 3,500 |
| 65 inch (any brand) | KSh 8,000 – 15,000 | KSh 2,000 – 4,000 |
Note: Power supply repairs are among the most common TV repairs in Nairobi due to unstable mains electricity. Using a quality surge protector or UPS significantly reduces PSU failure rates.
