TV cracked components on boards from lightning effect are among the most common—and often most expensive—types of TV failures in Kenya. A single lightning‑induced surge can blast tiny capacitors, ICs, resistors, and traces, leaving your television completely dead or displaying weird artifacts, flickers, or no image at all. At Pro‑Logic Technologies, we specialize in board‑level lightning‑damage diagnostics and repair, bringing your TV back to life without the need for a full replacement.
How lightning cracks TV components
When lightning strikes or a nearby power surge hits your home line, thousands of volts can rush into your TV through the mains, aerial, or satellite cable. Sensitive components such as ceramic capacitors, MOSFETs, diodes, and integrated circuits on the power supply board, main board, and T‑CON board are often the first to fail; they can crack, puff up, or burn out silently, leaving visible discoloration, carbon marks, or actual physical cracks on the board. In many cases, the TV will show no standby light, will not power on, or will power on but freeze, flicker, or show distorted lines—clear signs of internal board damage rather than a simple cable issue.
What happens when components crack
Cracked components on TV boards create open circuits, short circuits, or fluctuating voltages that prevent the board from generating stable power or proper video signals. On the power‑supply board, this usually means the TV cannot produce the correct 12 V or 24 V rails needed by the main board and backlight, so the set remains dead or behaves erratically. On the main board or T‑CON, cracked components can cause missing inputs, no picture, vertical/horizontal lines, or complete signal loss, even though the backlights may still glow. Ignoring these symptoms and repeatedly powering the TV can spread damage to other boards, turning a simple repair into a much more costly job.
Why board‑level repair beats full board swap
Many local shops respond to “lightning‑hit TV” by simply swapping the entire power or main board, which is faster but often unnecessary if the damage is isolated to a few components. At Pro‑Logic Technologies, trained technicians first perform a visual and electrical inspection of all affected boards, testing fuses, capacitors, MOSFETs, ICs, and traces to pinpoint exactly which components have cracked or failed. Only after accurate diagnosis do we replace burnt or cracked components, clean carbon tracks, and verify each power rail before re‑assembling the TV. This component‑level approach saves you money, preserves your TV’s original configuration, and reduces e‑waste compared to blindly replacing entire boards.
Our lightning‑surge repair solution
Pro‑Logic Technologies offers a structured lightning‑damage solution for TVs across Nairobi and nationwide: detailed board inspection, component replacement, and surge‑protection advice to prevent repeat damage. Our technicians work on power boards, main boards, and T‑CON boards for all major brands, from Samsung, LG, and Hisense to TCL and Haier, restoring normal startup, picture, sound, and input functions. After repair, we subject each TV to continuous operation tests and provide a clear warranty on parts and labor, so you can be confident that your set is not just “turned on” but fully restored.
Protecting your TV from future lightning hits
Once we repair your lightning‑damaged TV, we recommend installing a good surge‑protected extension, a quality voltage stabilizer, and avoiding leaving the TV plugged in during severe thunderstorms. Simple habits such as unplugging the mains and aerial/SAT cables during storms, especially in areas with frequent blackouts, can drastically reduce the risk of cracked components on boards. Pro‑Logic Technologies also advises periodic inspection of TV boards and power lines, so small, early‑stage issues do not escalate into full‑board failures after the next storm.
