I woud really appreciat eyou help opn this one. Was watching my tv this afternoon, and all was good but after dinner, when I turned it on the picture had the green sagging in the middle. I went ot the convergence, the green grid was sigging in the top middle and adjusting the red and green did not do anything. Any ideas??
