Why we shut off our T.V when the rain and lightning come. Explain?
Answers
Answer:
There is no point in switching off the TV during lightning. In fact, if your area has a lot of lightning activity, you may be endangering yourself if you try to switch off anything when there is lightning activity.
Why should we switch off the TV during lightning?
Switching off a TV used to actually remove all power from it with a real mechanical switch, however this would only protect it from mild surges or spikes of power. Lightning could still cause spikes that would easily jump the tiny gap between the contacts and damage or destroy the set. Just remember, lightning has jumped thousands of feet through nothing but air, so it wouldn’t hesitate to jump that last 1/8 inch or less gap inside the switch to blow up your TV.
Now you can’t find any tv on the market that still uses a real switch to turn them off. It’s receiving power constantly to operate the remote control circuit. Turning a new model TV off only turns off the receiving and display sections.
If you don’t care about your TV at all, then go ahead and just turn it off.
If you DO care about your TV, then unplug it completely. By ‘completely’, I mean not only the power cord, but also any other cables that lead to an outside source attached to it, such as the cable tv or antenna cable, ethernet cable, satellite cable, etc.
Cables to a DVD player, audio or video cables and such can be left connected, however with a close lightning strike enough power could be transferred to these to damage it also, but it’s not nearly as great of a risk as the cables from outside the house.
It doesn’t even have to be a direct hit by lightning, but as I said, a strike anywhere close can damage it.
