Green shadows all over the screen


You didn't say how old the set was and how much it's used, but the shadows you're describing sound like a bad green picture tube.

Hope that helps...

TV PROBLEM


This could be the start of convergence problems. Anytime you are dealing with color lines then is the convergence. No first you could check for loose connection and then change in value return resistor in the convergence area. Hope this helps!
