Instructions
Connect your PS3 system to your television using a composite connection cable. Composite cables have red, yellow and white RCA plugs. Note that some older televisions only have white and yellow RCA connectors; if this is the case, do not connect the red RCA plug into anything.
Turn on the television and select the "Video" input setting.
Press and hold the center button on the PS3 controller until you hear the unit audibly beep. The PlayStation 3 will start and will automatically revert back to standard-definition 480p mode.
