Thanks to your consuels, I have almost solved the problem but only in part, because I realized that the problem is in the graphic resolution. Last night I made several attempts, I tried to attack the PS3 through the very normal component cable (instead of HDMI), but also with the component cable home page can not be seen, but it shows.
I have a Bose home theater and all and everything (resolution and number of outputs) are all controlled by the setting from the Bose System.
It occurs to me that someone (ie my girlfriend) might have inadvertently changed something in the settings of the Bose. Tonight I feel and if I discover that she has put your hands (even though it knows you do not have to touch my robe technology) I will cut your hands.
