I tried degaussing the scope and it works perfectly now! I didn't think it would matter that much, but it did. Thanks for the tip!

The square waves look like trapezoids, and the 'no signal' flat trace curves downwards at both ends of the screen- no matter where the trace is placed up or down on the screen. Other models of this scope series has a geometry control, but this one does not. Any help?
