Since your TV does have high voltage capacitors within its components, before any type of repair or replacement of parts is started it is important to drain these capacitors of electricity. A high wattage resistor can be used to drain these components and prevent a potentially dangerous shock.
There is the potential of getting a severe shock when poking around in the back of your television, even if it is not plugged in. Always check to make sure any capacitors are drained as well as stand on properly insulated flooring and take safety precautions with regards to handling the television components.
One major problem that affects most televisions is the build up of dust inside the case. By removing the back, when the warranty is over, and gently brushing or vacuuming inside the TV you can help prevent a lot of problems with dust deposits. Never use water or any type of liquid to clean inside the television.
