i'm not using AVR, surge suppressor, line filter nor grounding.
i am thinking, our TV has something like those, built in, as it's a multivolt model.
my still-functioning flat screen CRT TV is over 15 years old.
i've been lucky, i suppose.
our TV set is located beside the open window that doesn't get wet, even in strong rain.
the instruction is to always put these appliances away from heat and wet.
errr...
solid capacitors... "XX times longer than ...what?"
many stores sell gadgets that are supposed to help cool laptop bottoms. personally, i think these gadgets actually work.
