Just got a ps3, but there some kind of problem. In initial setup when it asks to use hdmi cable (i was already using the hdmi cable) screen was turning on and off and making a sound. Then it went away after a lil bit. Now im enjoyin the messin around and stuff and i try out the ninja gaiden demo. When u start it up it has that black screen, i forget what it says but at that point it starts doin the crap again. Only for about 10 seconds of goin on and off like before. This alwalys happens!! Does anyone know if this is a faulty hdmi cable(monoprice) or sytem is bad or the 1.7 system update is bad? My tv is a westinghouse 37inch 1080p. Thanks for your help
