I've been noticing something odd. When I have my PS3 set to 1080p, every so often, the signal gets lost sort of. What happens is that I'll start my PS3 with it set to 1080p. A few seconds or a few minutes into a game, or even just sitting on the menu, my tv will flick off, giving me the window that says stuff like weak signal or no signal...stuff like that. That's what it does most of the time. Other times, it will do the same thing....only the audio will continue while the picture still flicks off. I have no idea why it does that. Is it the receiver ? I'm not so sure about that. The receiver isn't that old, only maybe 4 or 5 years old. An Onkyo. Just on a whim, I changed the PS3 to 720p. It's been a couple days and I haven't noticed the picture or picture AND audio flicking off. Do I maybe need a different HDMI cable ? I don't know if I should, seeing as there aren't really any 1080p games. I've only got one. And frankly, I didn't even notice any difference between 1080p and 720p. I haven't noticed any picture flicker on my blu-ray player....except sometimes when I have my air conditioner running. They're both on the same circuit and when the AC kicks in, the blu-ray player will sometimes lose picture.
