When you powered it off, was it already damaged. When you power it
on, does power on cause damage? You don't know if it was damaged
without power cycling. Did the damage exist or was the failure caused
by power cycling?

Static electricity created by human contact can cause damage. As
some components age (especially when containing a manufacturing
defect), then that component can fail when power is applied.

Lightning and other EMF - well a hundred foot antenna within 50 feet
of a nearby lightning strike can have thousands of volts on it. And
then we connect a tiny neon glow light from that antenna to earth.
Now the thousands of volts is reduced to tens. Many see the part
about thousands of volts and forget to learn how even a tiny glow
light can reduce that to insignificant.

Electronics routinely contain such protection. Otherwise, a nearby
lightning strike would mean every cell phone and automobile radio is
destroyed. Nearby fields even from lightning must never cause
electronics damage. Of greater threat is 18,000 and 20K volt
discharges by static electric from humans. But then protection that
also makes thousands of voltage on that antenna irrelevant is also
installed to make static electric discharges irrelevant.
