I have a sanyo TV model ds3225 that all of a sudden had a color change on the screen. It was hooked up to my cable box through the video 1 screen. Normally it displays video 1 on the top right corner while the TV is on. Recently when I powered the TV on some numbers where at the bottom left of the screen and in the process of pushing buttons trying to get it back to normal the color changed. Now my screen is green and the video 1 is no longer displaying on the screen. Any suggestions on how to get it back to normal?
