I have an Apple IIgs in OK condition. The monitor is giving me issues. First, it makes a horrible high pitched sound when turned on (only slightly subdued when there's a picture on the screen, but still rather intolerable.) Second, the picture is near the bottom of the screen because if I adjust the vertical location, the picture becomes completely distorted and starts scrolling up and down.

Is this something I can repair? Anyone here used to fix CRTs?

Thanks
