Recently, I want to play at Killzone 3. This was right after 4.25 update. I really don't know if this is related, but I guess. So when I update my ps3 to 4.25, everything was perfect. My ps3 model is a old fat 60GB made in december 2006. When I launch Killzone 3, I got the move related loading screen, right after, the little loading icon from killzone appear in the upper left corner for few second, then nothing but black screen.
Right after, my tv said no source detected, same for my home cinema...
I tried few things. System file recovering, since my ps3 was force reboot. I flush the last update for killzone 3 in game data folder and reinstall it, but nothing change. I try another game on my HD, Outland, and everything is ok.
