Expert Power & Audio System Repair at Your Doorstep
A television that won’t switch on, shuts off by itself, or has lost its sound is almost always a power-supply or audio-circuit fault — not a reason to scrap the set. FirstFix TV repairs power supply boards (SMPS), standby faults, startup failures and speaker/audio problems to get your entertainment running reliably again.
Power issues often trace back to failed capacitors, a damaged SMPS or surge-related damage; audio faults to blown speakers or amplifier components. Our technicians safely diagnose the board, replace faulty components with genuine parts, and advise on surge protection so the problem doesn’t return.

Power & Audio System Repair — Your Questions Answered
Very often, yes. A dead TV is usually a power-supply (SMPS) fault — failed capacitors or regulators — which we can repair at component level for far less than the price of a new set.
It’s the TV’s way of signalling a fault, frequently in the power board or backlight. The blink pattern helps us narrow down the cause during diagnosis.
Power boards carry high voltage and should only be handled by trained technicians — which is exactly what our team does, safely and to standard.
