Problem with PS3 Video Output

[SKREECH]

Hello Everyone.
I just bought a PS3. Until yesterday, no problem. I used the classic video output because I do not have HDTV. Then I went to a friend who has an overhead projector with an HDMI clable. It worked, it was super.
I then returned home and have used the exit Video classic. And then, my TV does nothing, it was complete darkness, I can not do anything.

What do I have to reconnect my console with an HDMI cable and then change the system to recognize again classic video output?

Thank you for your advice.

You hit something in the options to connect HD? If so, you have to reset the setting. check this link http://manuals.playstation.net/docum...deooutput.html

I did not hit anything, it was done automatically by answering a few questions of the system ...

Just keep pressing the button to start the ps3 until a second Beep. also try the link given by simond
