Picture has become distorted, especially towards the side of the television. The colour filters line up towards the middle of the television, but become distorted towards the sides.


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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - 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.

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 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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

The tv picture looks like should be wachting it whith 3d glasse


This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • 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.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

You can see some example photos and find a solution here on Fixya.

Faint lines show up when i get dark screens in movies


First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

Red screen on my sony kp-53s25,


That model is famous for bad green CRTs which can cause the screen to take on a red hue when the green cuts out that can also cause the set to get blurry also. Let me know if you need more assistance.

Our picture is green


This is not a user serviceable problem. Apparently the red and blue screen colour tubes/guns are inactive. Possible open green screen control. Also, if CRT type, the tube may be failing

Yes you have bad green and red crt but with an adjustment you can still use it. remove the front panel and you'll see the focus pack (it;s a black piece with 6 rotating knobs on it. Adjust clock otherwise the red and green screen (the bottom line knobs) till the lines has gone. The better way to check it is to adujt in video input with no signal, just black screen.
