    blue shadow at top and bottom...lettering is doubled and the whole picture is out of focus.this is a new problem,earlier a green screen was fixed by unplugging the tv and not using it for several months.Happened to turn it on and no more green.Is it true that they have to be de-magnitized?

Blue shadow


If the blue shadow is convergence you should have an option for convergence adjustment via the remote control to converge the blue onto the green. If it doesnt move then its probaly a IC problem. What make and model set do you have?

Blue and red shadows on screen


This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.
