The damage occurs because the voltage spike is so high that home appliances like TVs, chargers, microwaves, or anything plugged in or connected to the main electric panel cannot withstand the electrical voltage intensity.

What does a power surge do to a TV?

Lightning strikes nearby. The power cuts out for a moment, then returns. But when you try to switch on the TV, it doesn’t seem to work. Electrical surges can instantly overload and short out the circuitry of home electronics and anything else plugged into the wall, or they can degrade them over time.

Is it dangerous to leave a TV in standby mode?

Modern TVs, like most other appliances, do not use such high voltages, so presumably that danger is much less. On the other hand, if they are left in standby mode they are wasting power than an old-style switched of CRT TV would not be wasting.

Do OLED TVs suffer from Burn-in?

My OLED TV has a screen saver probably because of this, it also has other options in the menu to help reduce the impact/risks. Apparently early OLED TVs suffered more than the current models.
