Adjusting the brightness and background color Adjust the brightness dial of the color TV so that the brightness is appropriate, neither dazzling nor too dark. It should be better to watch the TV for a longer time without fatigue. Then turn off the color saturation so that the image is colorless and black and white. Color televisions with tone knobs need to adjust the tone knob to a minimum.
Adjusting the horizontal sharpness ratio can represent the strength of the kinescope signal under certain conditions. The contrast is adjusted, indicating that the signal strength applied to the kinescope is appropriate, and the horizontal resolution can be adjusted at this time. When adjusting the tuner knob or channel trimming knob, you should carefully observe the horizontal clear pattern in the test chart, make the fine vertical lines as clear as possible, and there is no trimming and trailing. At the same time, the sound is also required to be good and does not interfere with the image. In a color television test chart, the more recognizable position of the closest line is to the right, which indicates that the television has higher horizontal resolution.
Adjusting the Color Saturation To adjust the color saturation, first turn the color saturation knob to the minimum position, and then adjust the depth of the color according to the viewer's own preference. If the colors are too thick, they will lack realism. If they are too light, they will lose the meaning of color. A more appropriate criterion is: the skin color of the person in the image, especially the color of the hand and the face, should be close to the average person's color, ie, the color saturation knob is adjusted to make the color of the skin color close to the normal person's skin color. In addition, adjust the frequency to adjust the frequency adjustment knob.
Adjust the color saturation knob so that the white, yellow, cyan, green, purple, red, blue, and black colors of the test chart appear. However, the depth of saturation, which is generally not easily recognizable from the color bars, requires the help of the skin color standard in the upper part of the test chart. The male skin color (left) should be adjusted slightly darker than the female skin color (right) and be similar to the normal skin color. If it is adjusted too lightly, the color of the woman's skin will be close to white; if it is darkened, the skin of the man will become red, or the color of the skin of men and women will be indistinguishable. Only when the color saturation is adjusted properly, the image will have a good color effect.
