I've got a minor problem with my Panasonic TX-32DTX40 in that there is a mostly green & yellow line at the top of the picture some of the time only about 1 or 2 mm(mostly in centre of screen tends to feather out at both ends). This is more prevalent on some broadcasts than others and also it shows on all AV inputs. I think this is a minor set up problem but don't know the fix (last time I had this problem there was a horizontal & vertical hold adjuster at the back of the telly). Any knowledgeable TV buffs out there that know how to get into the set-up menu as it will be a lot of hassle taking this TV back. Thanks in advance .
