Surge suppressors on everything with a microprocessor in it (eg. computer, TV, sterio, etc.) And if you know it is a big lighting storm coming, then just shut everything down until it passes, since cheap surge suppressors may not be good enough to protect your expensive electronics from a close lighting strike surge.
The JVC was On a Battery Backup/Surge protector (We had it on Bat. Backup because the salesman told us it would save bulbs if electricity went out being it had a cool-down fan and cycled through a cooling stage when you turned it off.) The Bat Backup allowed us to shut it down and let it cycle.
In fact everything was on the Bat. Backup/Surge Protector except the subwoofer (Not enough plugs) it was plugged into a cheaper surge protector and it apparently allowed the strike surge into the Receiver/Amp and then into the speakers and TV, being that I found the connecting wire from the Subwoofer to the Receiver/Amp burnt off. The cheapy surge protector is sorta melty and of course doesn't work now.
When the lightning strike happened the power was off. It was late at night when it happened I was just going to bed. It had just started raining and as happens here frequently during storms the power went off. I went about turning off stuff including the big commercial AC unit. Just a few seconds after I clicked the Thermostat on the AC to off the lights sorta brightened and fluttered and at the exact same time a huge peel of thunder starting with the sound of someone breaking a stick as it was broadcast over a Rock Concert sound system at earsplitting level then sorta rumbling so loud it shook the windows.
It scared the living crap out of me and the hair stood up on my arms and on the back of my neck. It woke everyone in the house too hahaha.
Since everything was off including the electric we went to bed.
The next morning when the wife got up for work I got up also since it was hot in the apartment. I seen her off to work and I flipped the AC unit on and the compressor in it exploded hard enough to throw bits of metal all over the alley out side and even forced some into the duct work and slightly bent the squirrel cage fan that circulates the air.
And since the apartment has no windows that open and it was hotter than hell back in the TV areas we didn't turn anything on for several days till they got the AC fixed. So it didn't dawn on us for almost a week that everything was hammered due to lightning.
We have some eight foot florescent tube lights in one of the rooms and it did something to them that only one side of bulbs will light up on every fixture.
The AC guy told us we were very lucky it didn't start a fire.
