TV Circuit Board Diagnostics and Repair in Kiambu & Nairobi

By Prologictechnologies.co.ke

Televisions have become an essential part of modern homes, providing both entertainment and access to real-time information. However, like all electronic devices, TVs are not immune to faults. One of the most critical components of a television is the circuit board – the “brain” of the device. When a TV fails to power on, displays distorted images, or produces no sound, a faulty circuit board is often the root cause. At Electronics Repair Nairobi [ERN] Technologies, we specialize in professional TV circuit board diagnostics and repair services in Kiambu and Nairobi, ensuring quick and reliable solutions to restore your TV to perfect working condition.

Common TV Circuit Board Issues

Modern TVs, especially LED and Smart TVs, rely heavily on various printed circuit boards (PCBs), including the main board, power supply board, T-con board, and inverter board. Each plays a distinct role:

  • Main Board: Controls signal processing and input/output ports.

  • Power Supply Board: Converts electricity to various voltages required by the TV.

  • T-Con Board: Manages screen timing and image display.

  • Inverter Board: (Mainly for older LCDs) Powers the screen’s backlight.

Common signs of circuit board issues include:

  • No power or intermittent power

  • Blinking standby lights

  • No display or distorted display

  • Sound without picture (or vice versa)

  • TV turning off randomly

These problems can stem from voltage surges, overheating, physical damage, or aging components.

Our Diagnostic Approach

At Electronics Repair Nairobi [ERN] Technologies, we start every repair job with a comprehensive diagnostic check. Using advanced tools such as digital multimeters, oscilloscopes, and logic analyzers, our technicians test each board for:

  • Voltage irregularities

  • Burnt or damaged components

  • Faulty capacitors, resistors, or ICs

  • Broken solder joints or corroded connectors

Our in-depth testing allows us to pinpoint the root cause of the malfunction, whether it’s a faulty capacitor in the power board or a corrupt chip on the main board.

Professional Repair and Replacement

Once diagnostics are complete, our skilled technicians carry out precision repairs that may include:

  • Replacing damaged components (e.g., fuses, ICs, transistors)

  • Reworking solder joints

  • Replacing complete circuit boards when repair isn’t feasible

We source genuine replacement parts directly from trusted suppliers to ensure long-term performance. Our team is also well-versed with brands like Samsung, LG, Sony, Hisense, TCL, and more.
