Things You'll Need
Instructions
Purchase a universal cable compatible with the PS3.
Connect the PS3 plug from the console connection end into the "AV Multi Out" port on the back of the PS3.
Connect the five jacks in the other end of the cable into their color-corresponding jack ports on your TV, labelled "Y," "PB/CB," and "PR/CR" for video and "L" and "R" for audio.
Turn on the PS3 and TV to test the connection for both video and audio.
