8563E Unknown Fault

Hi

I am experiencing problems with a 8563E spectrum analyzer. Upon startup, or whenever the unit is preset it shows a block of green above the noise floor, making the unit unuseable. The only way to rid the unit of this is to turn on the video averaging, but I would like to know why it is doing this.

See uploaded picture for what it looks like

Thanks in advance
