I have replaced the coolant in my blue CRT. I tried to get a convergence screen using the code supplied with this unit, but nothing comes up, only a green "+" sign. I have totally screwed up the green convergence when I tried to center it using the # keys, then the <and> keys to get the green "+" to the center, which is what I thought I should do. Damn- now I have a great picture, but a green ghost that is way, way, way off from the rest of the picture. What in the beJesus can I do to correct now? When I pu tin the supplied code for convergence (06-25-97-menu) I don't get a convergence grid. HELP! Thanks Mark Allgood
