my ps2 stopped working after i finished a game. the credits were rolling and I wonted to start the next difficulty so I restarted the ps2, but all that came up was a blank screen so I tried to restart after a sec but it would not restart so I opened the cover and tried a different game that had a blue back, and that worked fine so I tried the first game and still no game starting. then I tried a compel of other game that had a non-blue back and they all did the same thing. the sp2 is a non-mod 1slim. PLEASE HELP!!!
