I ran across this problem when moving my Playstation 3 from my parents house to my house. I don't have an HD-TV(yet!!). So when I brough it over from my parents house (who have HDMI), to my TV (composite connection), the TV would just be blank.
This was because I had set the PS3 to output HDMI at my parents house, but forgotten to switch it to composite before bring it over to my house. So driving blind, I would never be able to find the menu to reset it.
By Sony had already though of this problem and there is an easy solution:
- Make sure the system is off.
- Hold down the Power Button for 5-6 seconds - until you hear the second beep.
- That's it, your video settings are reset and you should be able to choose your input and configure it from there.
