inside the TV there is a wire that has a suction cup at the end of it that sticks to the glass ,its a pretty thick wire,someone told me that it carries high voltage,not sure what this wire does or what its called or the little baseball size casing that it comes out of.it has a few thick red wires going into this casing that look like power wires

the lead to which you are referring is the ht lead which supplies power to the final anode of the CRT (picture tube). the baseball size casing is in all likelyhood (depending on the tv's manufacture/model) either the tripler or line output transformer (also called a flyback transformer). these components carry extremely high voltages-in some cases in excess of 30k and although the current is relatively small (about one third of an amp) it is still more than enough to kill you-so do not interfere with them-even after the tv is switched off!!. leave this to a qualified serviceman.

That is the high voltage lead that is electrifying the front of the screen and causing the electrons emitted by the tube to strike the phosphors that are inside that front face. When an electron strikes a phosphor the phosphor lights up (fluoresces) and gives off colored light as part of the picture.
To generate the high voltage cheaply the TVs use a cheap transformer (that baseball-shaped) object called a fly-back transformer. It takes a low voltage with high current (those thick wires) generated by an oscillator and steps it up to the needed higher voltage and low current (that wire going to the tube that has thick insulation).
If you touch it you can either get killed or get a shock that will make you jerk your arm and possibly cut your hand on something sharp inside the TV set. The wire is connected to a capacitor that stores charge even after the TV is shut off so if you touch it even with the TV turned off you can get the same shock.

It is called the high voltage lead or second anode connection. Not a magnetron... those are found in microwave ovens. Stay away from it, it carries 25 to 30 thousand volts which can remain there after the set has been off.

If you don't know what that wire is, you shouldn't try to service the TV yourself, you may electrocute yourself (not saying that would be a bad thing though).

Magnetron. It puts the picture on a tube television.

(CARONA CAP), It it runs from the "HTT to CRT".
