A fuse does not trip to annoy you. It trips because the circuitry is taking to much current. This can be just a little to much, taking it to trip after a few minutes or hours, or lots to much, tripping as soon as you switch on. Can be caused by a defective semiconductor, or a capacitor with a shortage. If you can't see anything wrong on the board, like a capacitor, wilt a rounded head, or a burned out semiconductor or even a resistor, you have to find out by measuring what could be wrong. Without the skills, don't even go there. It could be dangerous because of the high voltages in the TV.
