You can do it 1 of 2 ways, you could try moveing the picture tubes just use a small screwdriver and just give them a small turn, look at your picture you will then know if you went the right way. Or if you have it on your model you can sometimes self allin with the settings menu in your menu there maybe a screen allinment setting It allows the common user to reallin the screen them selves you use the buttons on the tv to line 3 x's up on the screen some models were bought out with this but not all.

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!!!

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.

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Sounds like an allinment problem with the color projection you can allin yourself via small screws on color tubes in rear. but be careful as tv needs to be on to do it.

Sony kp-51w5510 rear projection tv convergence


Lateral red or blue movement is accomplished electronically
via convergence alignment circuitry controlled by STK type IC's
Replace them both for reliability, then adjustments will work..

Convergence not lining up


Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.

Faint red lines in a curved arch like pattern


Guys I did this myself real easy. Just don't turn the corresponding screw too far. Only need to adjust it until the lines go away. Do it on a darker screen so the lines are more visible. I did the red 2 years ago and the green 6months before that. The blue lines are coming on my screen now and I've fixed it in 10 minutes. The TV is amazing.
