So I had my PS3 hooked up to my regular 480 TV and it was working fine. then I tried to hook it up to my 1080 tv with composite cables for HD and I got these weird lines that would move vertically across the screen changing the color. Then when I tried to hook it back up on my 480 (using component cables) I started seeing the same lines but they weren't changing the color. I tried holding down the power button to reset the video settings but nothing works and I still see the lines. I don't know if I need to try and get an HDMI cable or what. If you could help I would really appreciate it.

Thank you,
Michael
