Sometimes when I change TV inputs from cable box from DVD or from AppleTV, the TV screen goes pink, purplish colour. The only way to return it back to normal is to turn off & on the TV or unplug the HDMI then plug it back in again. The TV is normal when playing DVD or the AppleTV. This problem only happened when I got the new IPG. I keep rebooting it but same problem. I have the Cisco 8642 box. Anyone have any ideas what's problem here.? I don't want go back to the old IPG.
