Things You'll Need
Instructions
Unplug the HDMI cable from the back of your PS3 and TV, remove it from the area, and then position your PS3 in a spot where you can access the back panel.
Insert the single-connection end of the PS3 A/V cable into the "AV MULTI OUT" port on the back panel of your PS3, and then route the other end of the cable toward your TV's back connection panel.
Connect the cable to your TV's "A/V in" connections by inserting the white and red plugs in the "Left and Right" audio input connections and inserting the yellow plug in the "Video" connection. Reposition your PS3 as desired; it is now reset from HDMI to the regular hookup and ready for use.
