This could be caused by the loss of the power to the converge circuit or the failure of the converge chips-stk-xxx-xxx if the problem pops in and out it's a connection problem.

Faint red lines in a curved arch like pattern


For this problem, what you have to do is here I found this solution: Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labeled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. That should do the trick, Hope this is helpful. Please dont forget your rating.

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!!!

Color issues are harder to solve without seeing the problem. It sound like the red amplifier on the crt board is bad. Is there any red in the picture at all? If not, that will be you problem

Green semi-circle of lines on Samsung 55" HDTV (projection)


I believe i have the same problem myself. When my TV is on any of the Component Inputs without my DVD player turned on i usually get the normal green screen. But now that is a dip in the green at the top of the screen from the top left to almost the top right and black pushing down on the dip. Almost like a green curtain was sagging at the top and you can see the black behind it. It does this on every input and distorts every picture you see. The distorted picture has all the green slightly off from where the rest of the picture is and where the dip at the top of the screen is there is somtimes purple instead of black.

I know the basics of how the picture gets onto the screen and its my guess that the Green "gun" for lack of a better term and somhow come loose, or been missaligned to a great extent. I would love to find an answer to this problem, and anyones best guess as to how much a repair man will charge, just so i know the ballpark.
