Sound *noise* Interference on Screen

[OldFoo]

I am getting interference on the screen when I am adjusting the volume.

When I unplug the red/white leads on the sound board...there is no interference.



Any ideas...and thanks!

I found the problem....it was an unattached speaker wire that was hitting a part of the monitor chassis frame inside. All is fixed and working well now...))
