Want to know what is inside a TV? Whats are the parts called?

Here is some information from http://www.adisc.org/forum/computers-games/7991-name-internal-television-parts.html


 * Remember to use your own words but get your ideas from here**

First of let me tell you that if your going to take apart your TV then make sure that you know what your doing. The components/parts in your TV will largely depend on what kind of TV you have, for instance some of the parts used in a tube television set will be completely different from some of the parts used in a LCD set.


 * __TELEVISION TYPES__**

This is an antique tube television set Here is the newer tube TV This is a LCD TV Here is a plasma screen TV which is alot like the LCD screen TV

Since most people still have tube televisions I am going to assume that yours is a tube set? So here is an __extremely basic__ list of parts used in them.

//**__TUBE TELEVISON__**//


 * Cathode ray electron tube:** This tube emits one to three different electron beams that emit forward onto the steering coils.
 * Steering coils:** The steering coils basically move that beam around at like billionths of a second and then it projects that onto the televisions screen, for viewing.
 * Phosphor screen:**This is the screen in the front of your TV, it displays the picture that you watch.
 * Antenna:** The little rabbit ears that will be pretty much useless when the government moves to all digital broadcasts in early 2009.

Like the big green boards, the chips, things like that I believe that you are referring to the PCB, which stands for "Printed circuit board" which looks something like this usually. These will almost always vary from TV to TV and you should not really mess with them unless you’re a professional TV repairman.

Here are some basic parts you should be familiar with. CAPACITOR

RESISTOR

TRANSISTOR



TRANSFORMER



MICROCHIPS



Also here is a handy little diagram I found for you Those are some of the basic parts of a tube television.
