Adjusting the peaking
To adjust the Peaking potentiometers, do the following:
1.Using MS Paint and a spreadsheet, create a testing image on your PC desktop that includes squares, lines, text, and gradations of color. Use the illustration below as a guide.
2.Adjust the LF (low frequency) potentiometer until the image is free of streaking. When the LF is over adjusted, the streaking is the same color as the image, as shown below.
