Your TV is a delicate item and also an indispensible one in your household. In order to prolong its life, you can take certain measures such as:
i) Never clean your TV with soap water directly: The TV is an electronic item. Any amount of water or soap, however small, can damage its internal components. Usually when you clean your TV directly with soap water, the water drips into the lower side components of TV thereby causing a short circuit in the components, thus rendering them unusable. To protect such condition, it is advisable to spray some liquid on a dry and clean cotton cloth and wipe your TV with it.
ii) Never keep your TV on standby for long periods of time: You should not keep your TV on standby mode for a long period of time as any stray or induced sudden current from your dish or cable can severely damage the TV components. So, it is advisable to always switch off the main line of TV.
iii) Protect your TV screen: A TV screen is one of the most delicate and expensive components of your TV (generally not more than 1-1.5 mm thick). One should not apply any undue pressure on the screen at any cost. Special care should also be taken while cleaning it or during transport.
