i set my 2nd ps3 up on one tv and now i have moved it up to the bedroom but i get no picture or sound both times using the hdmi conection but i think it might be difrent resolutions setting
is there any way i can reset it to give me a picture
ProfessorHats right - I had the same thing. Once you set up the Ps3 for say, 1080p then unplug it and put it on a TV with a lower spec - you need to reset it. Holding down the power for 5 secs resets it. You'll see the power go off then back on.
Green screen tint ... Maybe look at the display settings further in the Ps3. Now its been reset you may need to put something back 'on'. (sorry if that's vague)
