I have a PS3 connectd to My Samsung PS-50P96FDX Plasma via QED HDMI cable with the PS3 set to 1080p, but ever since I updated the PS3 firmware to the latest version on the Menu screen I get a flickering on the picture where flashes of what is best described as White Noise but if I boot up a Game or Blu-Ray it stops.I have tried all 3 HDMI cables that I have which are all 1.3 compliant and it does this with all 3, and YEs the HDMI cable is firmly secured in but the PS3 and Plasma. Has anyone else had this?
