We just took this brand 46" LC750 Samsung tv out of the box, the problem is that it won't show any picture. We even tried hooking my PS3 to the AV1 outlet but still no picture even when we kept switching the scource. On top of that, even if we just turn the tv on and hit menu or try switching the scoure nothing shows up, we can hear sound but see no picture and it literally came in at 9 this morning. There is something else however, when we have it on a cable setting, and it changes commercial it sounds like, we can see the tv go darker but then it brightens up when it sounds like something is playing, help By the way, I made sure the PS3 was set to 480i, so idk what is going on.
