has anyone heard of or experienced this problem??? My 811 has a row of white dots across the top of the picture. At first I thought a light may be coming thru the holes in the back of the tv--that wasnt it. the dots are nowhere to be found on any of my 6 other inputs. I hoped my component cables were defective cuz the downrezzed pic using red,white +yellow cables is fine. I switched to the DVI output and the dots are still there. appearantly it is only a hidef problem. I am ready to call and swap boxes-- maybe get a cheap 921!!
