You may have a bad flyback transformer (high voltage trans former). The lines you're seeing are retrace lines caused by the picture tube screen set too high. This is often caused by the screen control opening up. This control is part of the flyback.

If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!
