Things You'll Need
Instructions
Turn on, hold, and reset
Turn your PS3 off, if it is on.
Hold down the power button for 5-7 seconds. You will hear the initial beep, meaning its powering on, but you want to wait for a second beep, which means it has reset the audio and video settings.
Configure the settings how you'd like them on the set-up screen displayed on your TV.
Repeat this step if you're switching to a different cable type on a different TV.
