Hello
From it menu option, suf through and come to automatic convergence display option and press Ok button on the remote control.

The List & Labels part of the setup lets you edit your channel list and choose or create a

personal six-character label for each channel.

Note: Changing List and Labels can be time consuming. You can change these at a later time by accessing the

Setup menu.

1. Press the left or right arrow to scroll through the available channels and choose the

channel you want to edit.

2. Press the down arrow to highlight the In channel list option. Press the left or right arrow

button to add (the box is checked) or remove (the box is unchecked) the channel from the

list.

3. Press the down arrow to highlight the Channel label option. Press the left or right arrow

button to scroll through the available list of 25 most common labels. The last option in

the list allows you to create your own six-character label for the channel (the first letter of

the label is highlighted).

4. Press the 1 or 2 number button to change the first letter of the label.

5. Press the right arrow to highlight the second letter, then press the 1 or 2 number button

to change the second letter, etc...

6. When you are finished creating your label, press OK. For model D34W20, your TV tunes to

the last channel available in your channel list. For models D40W20 and D52W20 only, the
Auto Convergence menu appears next.

Auto Convergence (for models D40W20 and D52W20 only)

Your TV's picture tubes might have been disturbed during delivery or after you moved the TV,

causing the color in your TV to be out of alignment. The colors adjust by starting auto

convergence.

1. Press OK to begin auto convergence.

2. When the auto convergence is complete, the Red center convergence menu appears. The

cross in the middle of the screen should be yellow. If it is not, use the arrow buttons to

move the red cross to overlap the green cross. Press OK when adjustments are complete.

3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If

it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK
(the TV tunes to the last available channel in the channel list).
Ok

Replace a color gun in your KP51HW40. Then adjust the picture brightness to eliminate these rings by turning a little button behind the front (cloth like) panel (the one covering the front bottom half of the set). You may have to to dim the lights to be able to do that properly. The little dial button as is in the middle.

Convergence is dead,must changed 2 convergence ICS and all it resistors.Know how to solders?Tries Tv repair World.com,Tvrepairkitscom to buy convergence kit to repair this ur self.The shop will cost U $300 for partrs and labors.

Yes.
The fix is to replace the two Convergence IC's( STK392-110's) with STK392-150's. They are located to the right side of the chassis and mounted to large heat sinks. Be also on the look out for some burnt resisters and or discolored resistors that failed becuase of the IC's failing. These would be located just to the left of the heat sinks. If they are burnt or severly discolored, you will need to replace them with the exact valued resistors. In this high current circuit it is a must.
I hope this helps,

pls rate cause people arnt rating

I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.

I've had the arcing horizontal lines from time to time in all three colors (differing occasions). I dunno the correct lingo for this stuff, but having the same TV and fixing it myself here goes. It helps to have another set of hands while doing this. Also, eventually you will need to work in the dark so have a small flashlight handy. Put your tv on an unused input so you always have a "dark" background.

Open up the front panel of the TV.... There are phillips head screws running down both sides around the back side of the panel. After removing the screws and the little side panels they screw into, the whole bottom half of the TV can be popped off. Be careful not to pull it off to far as there is wiring running to the front panel controls. (you can disconnect the wiring plugs if you need the panel out of your way, just remember where and which way they go.) Behind the main silver panel is a smaller panel made of a thin pressboard type material. Remove this panel as well. Inside this second panel you will find 3 little knoblike controls (that also have a screwdriver head) that control the "color drive" of the corrosponding guns. They have a little strip of locktite on them to keep them from moving but it dosent hold on to hard. I'm telling you all this from memory and I'm sure the real techs out there head's are about to explode due to my cavalier attitude toward all this. I wish I could tell you exactly which one is the blue but i've adjusted them all at one time of another and can't remember which one is which.

Pick your favorite knob and SLOWLY adjust it to the right. Just a little bit....too much and your TV will pop off and you'll think you've blown up your tv. (I did this once, and had to uplug the tv and let it sit for a little bit before it came back to life, I probably got real lucky on that one)

Now...as you SLOWLY turn this knob, one of two things will happen. one.....another color arc is going to appear on your tv...this tells you you've got the wrong knob. turn it back to where it was. two....your blue arcs will brighten... thats the one you want. Kill the lights in the room...the darker the room the better. Turn the knob down (to the left) until the point at which the arcs disappear, if you go too far, that color will be "underdriven" so you want to hit it just right. It helps to have someone at the back of the room to better observe the arcs, it can be hard to do this sitting as close as you have to be to adjust the magic knobs.

Repeat if you have any green or red arcs.

Use some locktite on the knobs when you have them where you want them, i've used nail polish if I didn't have locktite available.

Rebuild your tv.

Your set is having convergence problems, are the colors messed up in these areas or does it looks normal beside the arc? If the colors are out of line then convergence problems are on the way. Shut down and look at the convergence board for loose solder connections first, Then resistors that needs replacing. Last may have to change Convergence amps.
