So you’ve got a dead power supply and want to know why. The problem could be something simple, like a blown fuse or loose wire. If so, you might be able to fix the supply for less than $1. This article will outline how to replace a bad power supply fuse, saving you the cost of a whole new supply. WARNING! Working on a power supply should not be taken lightly or attempted by someone with little electrical experience. Even when the supply is unplugged, its components can remain charged and SHOCK YOU. If you are in doubt about your abilities, let an experienced repair technician do the work or simply replace the entire power supply. If you do decide to open a power supply, remember to UNPLUG IT FIRST. Also, DO NOT WEAR A SHORTING BRACELET when working inside a power supply. You do not want to be in the current path of a discharging capacitor. Remember that power supplies are not the high-dollar items they once were and an hour of a tech’s labor is sometimes more than the cost of a new supply. If you do feel confident to work on a power supply, you do so AT YOUR OWN RISK.
