HDMI cord from laptop worked on tv the other day. Now it doesn't. You can see the image behind tons of static (But not normal static, it has color and is in large blocks, but changes if I switch inputs and then go back)(Laptop shows no static). MY CORD does this on both ports. But our Xbox 360 Works on both ports. MY CORD works fine on my friend's tv. And her CORD worked fine on MY TV. Why won't MY CORD work on MY TV. I'm very frustrated. Please help!
