From electrical energy to mechanical energy
A radio uses electromagnetic energy
Old analog type TVs cannot just be "converted" to digital. You will need a converter box or buy a HD tv.
Heat energy
Heat energy
A sound system works by converting sound waves into electrical energy. The electrical energy is then converted back into solid energy that results in sound.
if you are using CRT moitor than computer will use more energy if you are using lcd monitor than TV will use more energy . i am not saying for laptops .they (laptop) also use very less energy compared to desktop .but totally depend upon type of monitor.
It becomes heat. You can feel it at the top of the TV set. All wasted energy is eventually converted to heat.
-- sound energy -- light energy -- heat energy
-- sound energy -- light energy -- heat energy
Energy cannot be created or destroyed, they can all be transformed into from one form to another.For example, light energy from the sun is trapped by plants and converted to chemical energy.OR... electrical energy can be converted into sound and light energy as with a TV set... or with a fan, electrical energy is converted into kinetic energy which causes the blades to spin... etc.....

The same happens when just about any device is turned on. The reason is that part of the energy that is converted is wasted - and the waste energy usually becomes heat energy.
Electrical to sound+light+heat
I assume you mean what it is converted to. It can be converted to many different types of energy; that's one of the things that makes electrical energy so useful. (The other useful feature is that it is relatively easy to transport.) For example, a heating device can convert electrical energy to heat; a speaker converts it to sound; a television set or a computer monitor converts it to light; etc.
The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.
