WF Bandmap Problem

John N0TA

I recently moved, and having a problem getting WF Bandmap set back up. On the Bandmap screen, I am only getting a vertical, black line, about 1/4 inch wide on the right hand side. The rest of the screen is basically white with the text on the top and right. K3, LPpan, soundcard. Any idea what is causing this?
