Connecting HP PC with Windows Vista to Samsung HDTV. HDMI cord worked previously, and will work with another computer, but now when I go to the HDMI1 source selection it says "no signal". the other source options say no connection. I designated the HDMI1 as PC.

Have you verified on your first PC that your video output settings are still correct? (mirror/duplicate, extend, show only on tv etc)
