I have been running my PS3 via HDMI to my 1080P LCD for six months now. In the last couple of days, there has been some very noticeable artifacting (I guess that is what you would call it) on the TV.

I am not sure this is the correct forum but it seems like it since it does deal with AV issues. So my Playstation 3 Slim has randomly stopped displaying anything over HDMI, there is no sound or video.
