1) check the voltage (with no aerial signal) on the collector of all three video output transistors (on the crt base) they should be +-5v of each other if one is different, then swap over this transistor with one of the other two and if color changes, its the transistor, If not then I use a 2k-4k wirewound and touch it from each collector to chassis in turn, and watch the screen (I use a mirror) each color should be equally bright with flyback lines, if not its probably the tube (CRT) faulty.

2) If all of tests are ok, then I find the three wires coming up from the the main pcb to the crt base panel and swap over the green/red and see if the color cast changes
If yes then its the chip on the main board, If no its on the crt base board, so check values of all the resistors there.

Hi,

Without a specific model to work on, would you pls check if the Sony has got a tripler, something similar to the one shown below?

If yes, try adjusting the white plastic knob and see if you can merge the 3 colors. Pls mark the original position to be able to revert to it if no significant improvement/change.

If not, pls post back exact model and additional info such as was there something done to the unit like repairs of some sort or anything out of the ordinary that happened prior to the color separation.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Why do i have a green screen after i turn the screen adjustment screw?


since every display color monitors are only work with 3 primary color which are red, blue and yellow. You could also search it that by mixing these colors, you could get any color your want. Thats how color monitors work. Now in case of green color, it creates by mixing blue and yellow. When you are turning the screen adjustment screw, the red color plug will become lose, makes it appear green.
I hope your got the reason.

The color red is offset from the color green


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,

Switch OFF TV. Open rear Cover. Switch ON the TV. Now, very carefully, (There are very High and Dangerous voltages inside, also, use a mirror to see the screen) adjust a red colored box called "H.STAT" which controls the Horizontal Convergence of the CPT. Should solve your problem. Check some Vertical portion of a object (Text in some Video Title, wall of a building, etc, ) as a reference.
