I have a KP-51ws520 that a friend gave up on and bought a new LCD TV. About a year ago, after a power outage in our neighborhood, this tv now has noticeable streaks across the screen at all times. Is...


It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?

The more you tell me the better I can help. I will post a photo or two of what convergence problems look like.
This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.

let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.

Picture is very blue, especially in dark scenes.


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

When I set the Directv receiver box to the 1080i resolution mode, the picture on the TV is ghost mode with red and blue outlines around each figures. please help. When I set the receiver to the 480i...


This may sound strange but I have seen something like this once before in this model----In the customer menu select Convergence---DO THIS WITH NOTHING CONNECTED TO THE SET FOR SIGNAL-- IF THE multipoint convergence looks ok---I saw one of these sets where the problem was the box that was giving the set signal---easy to find out if you have them swap that box out for another---The TV does not know(convergence wise) whether you are 480 or 1080---yes, sometimes the set needs to be adjusted in each of these modes for Convergence---the set I saw the convergence was ok in 480 but out the window in 1080----he had another box in another room and when we swapped it the problem was gone.

Let me know if this helps you---in the 480 you can confirm this by hooking a DVD etc and if that looks good---suspect the box.

If you have any questions let me know--I am here to help.

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

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.
