With a color bar test pattern from a test disc or other source on screen, the following adjustments may be made:
•The color intensity setting on your TV.
•Color adjustments using the color bars, which should be (left
to right) black, white, yellow, cyan (turquoise), green, magenta, red, blue, black.
•The color transition, seen as sharp separation of the bars.
•The performance of the color circuits in your TV (with “Video” signals); bar edges should show no vertical crawling dots.
Use the gray scale and the black/white fields below the color bars to adjust the brightness and contrast.
Brightness Adjustment
1.Turn down the color control on your TV until the color bars appear in black and white.
2.Adjust the contrast to the lowest level where you still can see all gray scale bars separately and clearly.
3.Adjust the brightness so that the bars in the gray scale are all visible. The bar farthest to the left has to be as black as possible rather than gray but the next gradation must clearly be distinct from it.
The bars in the gray scale should gradually and evenly change from black to white.
