Thin blue line on all pictures


Try resetting the electronics to factory defaults. Re the flash - if it continues to stick get it open and leave it like that until you find out just what it is that is causing it to stick. Mechanical issue and do able.

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.

Thin green line


Most likely your tv has a defective LCD panel. If it's in warranty, drop it to the warranty depot shop to repair.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.

Blue vertical lines - no picture


you did not mention if you have sound.but if you have sound your problem is in your video and vertical section.if no sound then you have to look into the IF section.if you are not a tech then you will have to take your set to repairman.goodluck.the tuner must not be over looked.an estimate of about $200.00 could be less.
