    Hi. This is my first post. My name is Steve. I am an undergraduate Audio systems BSc student in my final year at London Metropolitan. I am requesting help with a Gould DSO400 digital oscilloscope. I have a problem with the screen. The scope all seems to work OK except the screen is a very bright green and there are diagonal lines from top to bottom along the x-axis..:confused: I have tried adjusting the Black trimmer and the brightness trimmer. It helps to make the text and waveform a little sharper but doesn't darken the screen. Would anyone know what causes this kind of problem?
    Any help seriosly appreciated. I have included an attachment picture.
    Thanks,
    Steve.
