Dear info248,
A blue tint means that the Blue, or possibly Red, LCD is faulty.
You put in a used engine.

I have a sony KDS-R60XBR1. The lamp burned out so I ordered a new one. When I took the old one out, I noticed the area directly in front of the lamp, the first thing the lamp shines into, is a little dirty...


Use a eyeglass cloth or LCD screen cloth. Use NO solvants on it. Just dry cloth. ALSO goto the settings menu and put the tv in HIGH altitude mode. There tv's get too hot and the light engines go out. Green or blue tint. or dots. It also helps the lamp last longer.

How did I correct blue and red lines curved across a blank screen of my KP-57WV600 SONY Projection TV?


This is for if the lines are thin and arc.

You need to turn down the screen voltage for the blue and red CRT. I don't remember if the focus block is in the front or in the back of the tv on this model. Most projections have them in the front.

You could check the back access panel and look for a black box with six knobs as descibed in step 3 below. This is what you are looking for.

follow the steps below if it is located in the front:

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

4) Careful with the access panel removed, you are only inches away from very dangerous voltages.
5) slowly turn the R or B knob counterclockwise until the lines on the screen disappear.
Keep your hands away from everything else and only use one hand near the tv. put the other hand behind your back.

6) Once corrected, replace the panel and put the grill cover back on.

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.

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.
