No, you cannot. It is a HDMI only input HDTV. It has 2 HDMI inputs and USB inputs, but no AV cable inputs.
I do, however, recommend it. My brother in law just got one for his PS3 (you don't HAVE to use it with a PS3, it just has a PS3 logo on it) and it's great. The picture is astounding, the refresh rate is great for gaming. It's really fun playing on it. Nice size, too.
It can serve as a television for HDMI HD tv boxes, or for blu-ray/dvd players with HDMI, or a PC monitor.
