Sony kp-ws500 has very fine red and blue horizontal lines across screen tried adjusting convergence, and it didn't do anything

yes this could be the start of bad picture tubes . but you can adjust g2 controls and get rid of the line

I'm going to assume that the "lights" are images on the screen that seem to have a multi colored shadow. Within the menu there's a choice for convergence, when selected this gives a white cross centered in the screen. Using the arrow keys on the remote (left-right for vertical movement and up/down for horizontal) you will adjust the color that is "shadowing" or get all the colors aligned so the white cross has no trailing red or blue either horizontally or vertically. If you can't get it to adjust or there is no effect then repair is probably the only option.

I have Model # KP-WS500. The screen turn blue.

Hi,
Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

My KP-46WT510 picture is out of alignment. There is no conversion of the red, blue and green pictures on the screen. They're off by about an inch of each other.
Some tech told me that it was the power control that was bad. I can see the picture, just very blurred.
Is he right? The tv was not move at all before this started happening.

check your yellow fuse near ics

It is an adjustment, but it's an adjustment you may not want to do. It's the red screen control. It's located behind the front panel so the entire front panel has to be removed in order to access it-which will expose you to hazardous voltages. if you like, I can post detailed instructions on how to get that front panel off, it's kinda tricky.

did you try to adjust convergence
