Instructions
Turn off the PlayStation 3, if it is on, by holding down the "PS" button on the controller, or by using the "Power" button on the system.
Hold down the "Power" button on the PlayStation 3 system for several seconds. You hear two beeps. This indicates that the system is resetting its video input.
Press the "Power" button to turn the system back on. It may take several seconds for the system to power on. You will be notified that an HDMI device is detected and asked if you want to use the HDMI setting. Choose "Yes." Select "Yes" two more times and the system will reset, now using the HDMI input.
