Things You'll Need
Instructions
Plug your coax-to-RCA adapter into the coaxial antenna input on your older television set. The coaxial cable on the adapter screws on the exact same way the coaxial cable connected to a TV antenna would.
Connect your PlayStation 3's composite RCA video and audio cables to the coax-to-RCA adapter. Plug the cables into the adapter the same way you would plug them into the back of a TV.
Connect your PlayStation 3's composite RCA video and audio cables to the back of the console. The other side of the cables uses a proprietary input that will only work with the PlayStation 3 console. Use the input with the word "MULTI" written above it.
