If it's a DLP TV you might need to replace the bulb.

Blue lines on screen


Go to a unused video input and examine the screen----if you see blue with slightly curved trace lines the blue screen control for the set is set just a bit too high.

The wavy when cold is a issue with a board in the set--Hyper board--the warmup until it begins to work will gradually get longer and longer.

The blue: look at set on a unused video input--if see faint curved blue lines with some blue visable on the screen the blue screen control needs to be adjusted just slightly down until the blue and curved lines are not seen.

If the lines are slightly curved and stationary on about 2/3 of the screen its either the Blue CRT or the Blue CRT drive board which is having the problem.

Blue curved line near top of screen and out of focus if hand is held over blue light it goes away


It sounds like the convergence circuit has failed for the blue. The repair should be done by a professional. Cost wise you are looking around 250.00 to 300.00.
Hope this helps,

Blue curved line at top of screen and yellow curved line at botto


Do you by chance have any speakers sitting on top of the tv or right beside it. Speakers are unshielded and will cause this effect.

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.

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).
