The sound on this projector is shrill. I can understand
what is being said, but it is shrill and distorted. The problem seems to relate to the S/N (Sound/No Sound)
switch. Once I was able, by jiggling this switch, to get normal sound, briefly. Otherwise the projector, both
sound and silent, 8mm and Super 8, works fine.
What can I do
