How Lightning Affects TVs

TVs can be damaged by lightning but only in rare cases. Also, newer TVs are usually more sensitive to electrical surges and are more likely to be affected by a power surge caused by lightning.

This doesn’t mean that older TVs cannot be affected by lightning. Lightning can affect your TV and other electronic devices and electricity supply in 2 different ways;

  • Direct Strike

A direct strike occurs when stormy weather with lightning causes electric shock or power surges by directly striking your home or electrical system. You can tell when your tv dies just after a lightning strike and won’t come on afterwards.

This strike can cause significant damage to your devices and even your home, as it can start a fire. Usually, the damage caused by this strike is irreparable.

  • Indirect Strike

Indirect strike happens due to lightning striking areas that are not directly connected to your home or electrical system but can still affect them. In many cases, this is how lightning affects your TV, and the damage is minimal and can be easily rectified.

The most common way by which lightning affects TVs is by blowing up the main fuse. If the main fuse isn’t damaged, the damage is probably in another part of the TV.

In addition, signals to the TV can get lost through HDMI ports as a result of lightning. When lightning damages your TV, the repair can either be simple or complex.
