Default Re: Sharp MZ-80K help needed on repair

Asked someone in the sharp Facebook group who said this.
It's a monitor issue. The flyback transformer isn't settling down properly after a VSYNC. The computer part is working correctly and the display is correct, only mistimed until it settles down.

Check the caps and diodes in the monitor scan control section.
