If the lines change or go away when you move the lid up and down, then you need a new LCD cable. If they stay the same, then you need a new LCD.

Please note: That test is NOT fool proof, but does work 99.9% of the time.

It appears to be convergence issues. Red, green,


Projection TV2_bing.gif 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, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 flash2_bing.gif 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

There is just three lines that show red, green and blue.


It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Coloured vertical lines down lcd screen


To isolate the issue, i strongly recommend to connect the notebook to the external monitor by VGA port which had BLUE colored on the notebook. So that if it is normal then you need to confirm the issue is with the LCD display.

Green/Blue distorted Colors


Color issues are harder to solve without seeing the problem. It sound like the red amplifier on the crt board is bad. Is there any red in the picture at all? If not, that will be you problem

Lamp issues


No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
