Hi Guys,

What board is responsible for making the screen scroll slowly from bottom to top?

Its scrolls with no source applied... I just did a reinitialization and I can't keep the screen from scrolling... :(

I just found it... I have a defective vertical board. It looks like one of the power transistors grounded itself out.
