What you describe is known as a convergence board problem. Its a fairly common problem. You can read more about it herein this Fixya Tip.

Replace STK-392-110s or 150s upgrade with 180s replace both ics.
SOURCE: convergence problem
Replace the Convergence amplifiers. Mine did the same. It was like watching a 3D movie without the glasses. It is not hard to do for someone who knows their way around a circuit board repair. Otherwise call a reputable service shop.

The problem you have is the 2 STK - 392 convergence integrated circuits need replacing the cost in the UK is about £150.

There are several things that can cause this. There is a "light pipe" that connects from the lamp to the color wheel. If the mirrors inside have become dirty, broken, or have shifted it will cause the picture to do this. Also the color wheel itslef could be dirty or worn out. And the final culprit could be the light engine itself. You can have any in home TV tech test these out for you.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!
