Instructions
Plug one end of the HDMI cable into the slot marked HDMI on the back of the PS3.
Insert the other end of the HDMI cable into an open HDMI slot on your new TV. Many TVs have more than one HDMI slot. It does not matter which one you use. The slots on your TV are typically labelled HDMI, or HDMI 1, HDMI 2 and so on.
Turn on both the TV and PS3.
Press the "Input" button on your TV's remote and then select the input that corresponds with where you connected your PS3 or until you see the video from your PS3 on the screen.
