< Method of Readjusting Video Levels >
If the video composite output is not within the range of rated value, the video level is readjusted in the following
method.
Turn the video level adjustment volume (VR1671) to adjust its level to 1.0 0.05 Vpp.

When the result is not satisfactory,
adjust the level to 1.0 0.05 Vpp.
If the result is not satisfactory, check to see if there are any problems with resin flux cored solder and other
defects in the applicable line, vicinity of major parts stated in the above diagram and peripheral components.
