Lightning Strikes and Dead Motherboards: Why Your Surge Protector Failed
A severe thunderstorm rolls through, lightning flashes, and the power flickers. When the grid stabilizes, your expensive TV, game console, or smart appliance is completely unresponsive. You thought you were safe because everything was plugged into a surge protector, but that inexpensive plastic strip often provides a false sense of security. Here is the engineering reality behind power surges, why your defenses failed, and how component-level diagnostics can bring your dead electronics back to life. This Behringer mixer was rendered completely dead after a lightning strike jumped the surge protector. Instead of replacing the expensive unit, we use component-level bench diagnostics to locate the blown voltage regulators and rebuild the power delivery system. The Surge Protector Myth Most standard surge protectors utilize a small internal component called a Metal Oxide Varistor (MOV). When grid voltage spikes above the standard 120V, the MOV absorbs the excess energy and shunts it s...
