Simple answer: Electrical energy comes in and heat, light and sound energy goes out.
There are two input sources, the electromagnetic signal that is the actual information of what is to be displayed and there is also the electric power provided to operate the television. Typically, the power comes from an electrical cord plugged into the electrical outlet on the wall and the signal is a cable from an outside source or an antenna.
The input energy is electrical energy to power the TV and the signal is electromagnetic energy.
The output of primary interest is the image on the screen which is light energy, so the television puts out light energy which is also electromagnetic energy.
The television may also produce sound, in which case there is sound energy put out.
In the process of making light and sound, the components of the television heat, so heat energy is put out.
Summary:
Input: Electrical energy enters in two forms, electromagnetic signal and electricity. The electricity is the far greater source of energy. The energy in the signal is tiny.
Output: Heat, light and sound exit the television. Heat is the largest and in excess of 90%. Sound energy will be substantially greater than the amount of energy contained in the light.

What energy transformation takes place when sunlight strikes a house?
When sunlight strikes a house, the energy transformation that takes place is from radiant energy (sunlight) to thermal energy (heat). The house absorbs the sunlight, which then gets converted into heat energy, warming up the interior.
What energy transformation takes place?
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
What energy transformation takes place in the engine of a typical train?
In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.
What energy transformation takes place when a lawn mower is used?
When a lawn mower is used, the energy transformation that takes place is from chemical energy stored in the fuel (such as gasoline) being converted into mechanical energy that powers the movement of the mower blades. The mechanical energy is then used to cut the grass and do the work of mowing the lawn.
What energy transformation takes place in a bicycle?
In a bicycle, the energy transformation involves converting the chemical energy stored in the body into mechanical energy by pedaling. This mechanical energy is then transferred to the wheels, where it is further transformed into kinetic energy to propel the bicycle forward.
