What is a power surge and how does it affect my TV?
A power surge is a sudden and brief increase in electrical power that can damage or destroy electronic devices, including TVs. It occurs when there is a sudden increase in voltage in the electrical grid, often caused by lightning strikes, downed power lines, or utility company errors. When a power surge reaches your TV, it can cause damage to the internal components, leading to a range of issues from minor malfunctions to complete failure.
The effects of a power surge on your TV can vary depending on the severity of the surge and the quality of your TV’s internal components. In some cases, a power surge may cause your TV to malfunction or shut down temporarily, but it may recover once the power is restored. In more severe cases, the damage can be permanent, leading to costly repairs or even requiring a complete replacement of the TV.
Can a power strip or extension cord provide adequate protection for my TV?
A power strip or extension cord with a built-in surge protector may offer some level of protection for your TV, but it is often insufficient to protect against severe power surges. These devices typically have limited joule ratings, which measure their ability to absorb surge energy, and may not be designed to handle the high levels of energy released during a severe power surge.
Additionally, not all power strips or extension cords with surge protection are created equal, and some may not provide any meaningful protection at all. To ensure adequate protection for your TV, it is recommended to invest in a dedicated surge protector specifically designed for high-end electronics like TVs.
How do surge protectors work to protect my TV?
Surge protectors work by absorbing or diverting electrical surges away from your TV, preventing them from causing damage to the internal components.
