Hello all, I'm new here & am sorry if there is an obvious solution here but yesterday I got a Samsung UE40D6750, I love it so far & watching BluRay's is phenomenal. I've got it hooked up (via HDMI) to a Samsung BD-D8500. When I switch the TV on, the image (via the aerial) is pretty bad, shadowy, snowy etc but when the BluRay machine is switched on, the image is great. I don't understand why there should be any difference. What's going on? Oh yeah, also sorry if this is posted in the wrong place too.
