Repairs to "Old Type" CRT TVs?
All older types of TV's are known as CRT 'Cathode Ray Tube' TV's. This is what they use to display an image. These type of TV's are bulky and although some CRT TV's do have a flat display tube (flat screen) they should not be confused with flat panel display TV's such as Plasma or LCD. CRT TV's break the signal into separate audio (sound) and video (picture) components. The audio part feeds into an audio circuit which uses a loudspeaker to recreate the sound that was recorded in the studio.
How does a CRT TV work?
Unlike LCD and Plasma TV's, CRT TV's do not produce an image composed of individual pixels, rather the image is composed of a series of horizontal lines drawn in sequence across the display. The video signal is sent to another circuit. This fires a beam of electrons (fast moving negatively charged particles inside atoms) down a long Cathode Ray Tube, as the beam flies down the tube. To precisely direct beams, a copper coil is used to create a magnetic field inside the tube This field move the beams horizontally and vertically. By means of applying varying voltage to the coils the beam can be positioned at any point on the screen. The electron gun circuit splits the video part into separate red, blue, and green signals.
The electron beams pass through a grid of holes called a mask, which directs them so they hit exact places on the screen. These beams hit the phosphors on the screen, this pattern of red, blue and green dots builds up into a coloured picture. The video circuit therefore can build up an entire picture by lighting up some spots and leaving others dark.
