Generally, the white screen means that the video signal is stronger than
the machine can accept. It is similar to the effect when one records
music on a tape deck and the volume is maximized. In that case, the
sound goes to a blur of noise. In the case of your AV Series Macintosh,
the result is a white screen. The opposite is when there is no signal at
all and the display is completely black.
If the VCR or Television has an option for changing the video level,( it
may be labeled 'Attenuation On/Off') try setting it to a lower level.
As an alternative, try adjusting some of the Video Settings such as
Saturation, Brightness, and so on. By tweaking those adjustments, he may
be able to achieve a satisfactory solution.
