I accessed the TV through an ethernet cable and ran the tests provided by Chipper Check. The tests indicated that three differences exist between the default and present settings. I checked the box the box to change themand now the HD part of the TV has pictures scattered across the screen. Bht only on the 1080I part. How do I reload the defaults or change the items that I changed? Is there a manual that will tell me where in the memory the changes need to be made?
