The Right Way To Discharge Capacitor In Switch Mode Power Supplies

values of this type of filter capacitor are 220uf-the printed circuit board or circuitry can be damage

There are three ways to discharge the big filterHowever, if you know that the capacitor stored

1)Discharge it with a screw driver (notwith a small screw driver.
