Yes, your convergence is off. There is a function in the menu for adjusting these propoerties. It is supposed to be done monthly but rarley is. If it is ten years old or more, the cooling fluid in the projection tubes can get low, causing fish bowl effect. Not a cheap job and time intense. Try adjusting the convergence first. It gives you three screens to aling each color then save. Good luck!
