I had a cord to use the dvd player with a tv, but cannot find it. I purchased another one , but the video will not come thru correctly. I cannot find my instruction maunual and want to see if there is something else I need to do. I switched to A/V output with the source button and that is when I get the messed up image (you can't make it out at all). With using the source button I get nothing but audio.
