My Xbox Arcade (circa 2008) seems to be having an issue with the video not Displaying correctly. My Xbox usually operates with a standard definition television and a standard A/V cable. However, I moved it to a 1080p television with an HDMI cable and adjusted the display settings to optimize visual performance for a single session before returning the Xbox to my standard definition television and A/V cable. Ever since that time, my console will not display properly even if I move it to an HD TV unless an HDMI is used. Ive tried troubleshooting using the the Y button and Right Trigger button as suggested by this site's support section but that does not work either.
