does tv have s-video input?

No s-video. Check online for a user manual, but be careful NOT to look at the E320i-AO (which is "i" for internet capable, as I understand it). Inputs include 2 HDMI ports, one "component A/V" (RCA-style plugs), and USB, plus coaxial cable for antenna or cable service. The TV can switch back and forth between FOUR inputs: 2 HDMI, plus component A/V, plus one coaxial cable.
