If you suspect that your equipment has an electrical problem, you should unplug it immediately and contact a qualified electrician. Attempting to repair electrical problems yourself can be dangerous.

By taking precautions to protect your equipment from electrical problems, you can help to prevent D.O.A.

Power surges

Power surges are one of the most common causes of electrical problems that can lead to D.O.A. A power surge is a sudden increase in voltage that can damage sensitive electronic components.

Lightning strikes: Lightning strikes are a major cause of power surges. When lightning strikes a power line, it can create a surge of voltage that travels through the power grid and into homes and businesses.
Downed power lines: Downed power lines can also cause power surges. When a power line is downed, it can come into contact with other objects, such as trees or buildings. This can create a short circuit that can send a surge of voltage through the power grid.
Faulty electrical equipment: Faulty electrical equipment can also cause power surges. For example, a faulty transformer can create a surge of voltage that can damage equipment connected to the power grid.
Switching on or off large electrical loads: Switching on or off large electrical loads, such as air conditioners or refrigerators, can also create a power surge. This is because the sudden change in demand for electricity can cause a momentary increase in voltage.

Power surges can cause a variety of problems, including:

Damaged electronic equipment: Power surges can damage sensitive electronic components, such as transistors and capacitors. This can cause equipment to malfunction or fail completely.
Data loss: Power surges can also cause data loss. This is because power surges can disrupt the operation of computers and other electronic devices, which can lead to lost data.
Fire: In some cases, power surges can even cause fires. This is because power surges can overheat electrical wiring and components, which can start a fire.

Improper installation

Improper installation is another common cause of D.O.A. This can occur when equipment is not installed according to the manufacturer's instructions.
