what would cause the image on a CRT to shake in 240p mode? The OSD/menu doesn't shake at all, but text boxes on my RPGs on the bottom half shake pretty noticeably. Much harder to tell in 480i, but does that sound like a Capacitor issue? Tried switching between two models of the PS2, & went from third party component cables to official S-Video cables & the screen still shakes in the same lower half of the screen o matter what model or cable I use.
