They should be adjusted to set voltages. however it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels. Hope this helps.

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:

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.

Older 90's projection screen. 52 inch


Try opening up the front cover under the speaker outer cover, most speaker fronts should just pull off if you don't see any screws holding it secure near the side close to the front cover. Then there is about 4 or 5 screws that hold the front inner cover on. You are looking for a small black box with 6 adjusting screws . Three of these are for adjusting the focus and three are for adjusting the amount of current going to the CRT's. The markings are very small but you can try turning the Blue screw down and that will decrease the blue ( marked with a B). But if this just makes the other colors seem more powerful you may have a bad blue CRT. There is adjustments for three color CRT's ,Blue , Green and Red, try playing with the Blue and try to get it the way you think it should look but if the Blue just does not want to work right the Blue crt is probably gone.
