Recently on my Vizio HD tv, my a/v composite connections have started to give me a quick flash of scrambled, color static every 12 seconds or so. The video plays fine otherwise. Older video game consoles hooked up to it are interrupted at regular 12 second intervals by this quick static. I know it isn't the cord, I've tried several. It didn't use to do this. Is there any way to clean the composite in connections, or is it possible that something more interior is causing the trouble?
