TV power supply boards (PSUs) keep your screen alive by converting AC mains voltage into stable DC power for components like backlights, mainboards, and audio circuits. When yours fails—symptoms include no power, flickering, or shutdowns—replacing it restores functionality fast. In Nairobi, Luthuli Avenue stands out as the go-to hub for genuine PSUs across brands like Samsung, LG, Hisense, TCL, Sony, and more. Pro-Logic Technologies, your trusted supplier at Luthuli Avenue, stocks them all. Call 0723 763173 for same-day pickup or delivery across Nairobi and environs.
Common TV PSU Failures and Quick Diagnostics
PSUs handle high loads, so they wear out from power surges, overheating, or capacitor aging. Nairobi’s frequent blackouts and voltage fluctuations accelerate this—expect issues after 3-5 years of use.
No power at all: Blown fuse or primary rectifier diodes. Test with a multimeter for 220-240V input.
Powers on briefly then dies: Failing output capacitors (bulging tops signal replacement time).
Backlight failure: Common in LED TVs; check 24V or higher backlight rails.
Strange humming or buzzing: Faulty inductors or MOSFETs.
DIY check: Unplug the TV, discharge capacitors with a resistor, and inspect the board for burnt marks or leaks. Tools needed—a multimeter and soldering iron—available nearby on Luthuli. If unsure, bring your model to Pro-Logic; we diagnose free.
