    Please help!! I have the problem that you described, thin curvy blue lines across the screen. How do I access that blue gun that you mentioned, and if not that what is that open CTR that you mentioned? the problem is as follow: "curved lines from top to bottom of screen about
    2-3 inches apart. They can only be seen when the screen is dark or in a
    dark scene. Otherwise you can't notice it."
    Thank you for you help. MC

    We moved last week and when I switched on the TV I noticed some very thin curved lines that cross the screen in the horizonal, only noticable on a dark screen. I'm not sure what color they are, perhaps blue or green. These did NOT exist before the TV was moved. I contacted he shipper and he is supposed to "send some one over." If any one as any ideas I'd like a heads up so I can keep an eye on things. Thanks.

    I've had the same problem for a good year or two now. I was told it was from leaving it on overnight or something. I think that's ********

    I had the same thing happen, but now it is now turning on

    I had the same problem. The solutions below worked great. The six screws are accessable from the rear on the edge right below the handholds for moving the TV. As you "pop off" the front speaker grille, it is easiest to work your hand along the top and bottom to pop out the plastic holders. Don't pull the grille out too far as the control panel running down the front is attached by wires to the rest of the TV. If you do this carefully, you will not have to detach these wires, you can just pull it out a bit and get access to remove the cardboard (actually more like masonite on mine). The six buttons are clearly visible.



    I adjusted the lower left as suggested. I think I went to far as it turned off the TV and started the standby light blinking. I waited about 15 minutes, and even thought the blinking had not stopped, turned it on again, and the lines were gone.

I followed GuestUser/ Slinteriors advice and I fixed it. Open the front of the TV and there are 6 little nobs in the front. The botton 3 are what you need to adjust. from left to right the color controls are BLUE, RED GREEN. For the blue lines, slightly (I really mean very slightly) turn the botton left nob clockwise (right).

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.

Are the lines really thin curved lines? If so try turning down the screen control for the blue gun that may help. If not it can usually be traced back to an open resistor on the CRT circuit panel of the affected CRT. Let me know if you need more info.

This may be nothing more than dirt, hair or dust on the picture tube magnifier glass ( you can clean this by opening the front and cleaning like you would a window glass) or it may be more serious like a high voltage divider control. I would suggest you try cleaning the tubes first and if it's not that, then seek qualified help. ( PS. Always unplug the set from the wall before working inside the set ).
I hope this has helped.

hello High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

I have a KP-65WV700 and the screen looks a lil to green


OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

Blue gun control


Remove the front speaker grille and also the smal;l access panel and you will see a small control box with 6 switches 3 control the focous and 3 control the screen control. The screen control will be laid out like the CRTs are Green in the center and blue and red on either side just turn the blue down very little or you will make the CRTs shut down.

take the back off there should be a small rectangle with 6 buttons on it 3 for focus and 3 for the G2 (screens) some models have this control in the front behind the speaker grille behind an access panel and others have the control switch on the circuit board that is attav=ched to the crt neck. Either way its just a small switch much like a volume switch but smaller. Depending on what chassis you have it will be in one of the 3 areas I have mentioned. just turn it down a little. If that doesnt take the lines away you will need to trouble shoot the blue drive circuit.

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.
