1, adjust the image contrast Contrast too strong will reduce the level of the image, appear stiff, and lost a lot of image details, but also the occurrence of audio interference image phenomenon. Contrast adjustment is too low, it will also reduce the level of the image, it seems very laborious, so need to use the contrast knob correctly, call out six clearly distinguishable gray levels, so that the leftmost level just does not shine, and the last one The level of brightness is appropriate. When the color saturation button is turned off, because there are different signal levels in the color, their levels should be clearly discernible;
2. Adjust the brightness and background color Adjust the brightness dial of the color TV so that the brightness is appropriate. Do not dazzle the eyes or adjust the brightness too much. You should watch the TV for a long time without fatigue. Then turn off the color saturation so that the image is colorless and black and white. A color TV with a tone knob, the tone knob needs to be adjusted to a minimum;
3, adjust the horizontal resolution contrast under certain conditions can represent the strength of the kinescope signal. 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;
4. Adjust 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.
