Warning
Unplug the TV and leave it unplugged for a day before starting work. This will give it time to discharge the lethal voltages that may be stored in the capacitors, reducing your chances of shock.
Ground yourself to remove static from your body. The static in your body may damage the delicate circuitry found inside of TV sets.
Look up the specific model of the fuse used in your TV. Using a different type of fuse may further damage the TV.
