Televisions is not a major source of CFCs.
Step-by-step explanation:
CFCs (Chlorofluorocarbons) is used in refrigerator to maintain the temperature for preserving food items. Similarly in air conditioners CFCs used to maintain the temperature in the particular place.This CFCs acts as a medium through which heat is transferred through the freezer and refrigerator compartments via the heat exchanging coils Plastic foams used in food packaging also involves the use of CFCs.
But Television is an electronic device which involves transmitter and receiver and cathode ray tubes to display images and videos and hence doesn't use CFCs in it.
