Hi. When I sometimes boot my 360 up, the graphics I notice have a blur effect or a fuzzing effect. After a few minutes, it goes away at random, and then comes back again at random. I get pissed off with it because it gives me a headache, and I rip out the power cord. When I plug it back in and reboot the 360, it works perfectly fine. Any ideas what this is? It has never red ringed, overheated or been opened. It is a 2008 model (falcon iirc) I think the HANA chip needs a good clean reball. Something must be lifting or not making a good contact. I say this, because after the system heats up and I unplug > re-plug the console, it works fine afterwards. It can not be a grounding issue with the component cables, because there are 3 of them, plus the additional 2 for audio.
