And There may be considerably from the thousand volts in the majority of shopper electronics, normally the best voltages is to the enter aspect in the power supply which happens to be line voltage (110-240V in most cases). I’ve repaired the power provide in my DirecTIVO unit, Liquid crystal display screens, desktop motherboards, and desktop Laptop or computer power supplies(and in a single situation Using the power source still hooked up to the computer but unplugged) mere minutes right after unplugging and disassembling it, the circuitry is normally ample to empty the voltages of your power supply.
