LCD TV

One preventative measure is to wrap your TV with blanket, thicker blanket is better. And if TV is anywhere near a concrete flooring; a Plastic wrap is need on top of the blanket and make holes for air to breath if moisture build inside.
Plastic wrapping also prevent any insects find its way to nest inside the TV.

And before turning the TV on – make sure it's completely dry and plug the TV for at least a day before; this will charge the power supply capacitor and condition it a bit before use. However other TV components can only be charge up after TV is turned-on.
