Anyone else get this on the sky menu on a plasma, slight line streaks, pic attached. Got a new TV today running a 6m hdmi lead from the sky HD box. Its the ones going out left from the channel titles boxes left hand side. Also when I view the TV close theres lots of green dots, especially around blacks, its a brand new LG 50PN650T. Any ideas. I cant see the dots when stood a few feet away.
