Sounds like your convergence IC's have finally gone bad.. they seem to last 5 years on average.. have a look here: http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

3 screen colors have separated and screen is bowed in the middle.


I take it this is a projection TV. so they use three lensed CRTs red green and blue. you should have a setup screen that projects a grid pattern. red green and blue. there is SOMEWHERE a adjustment that overlaps the three projected grid patterns. Making a WHITE single grid pattern. red green and blue make white light. Pin cushioning is the bowing. you may find a POT to adjust on the back of the set. I have no idea what set you have.
Lastly.. Pin cushioning can also be caused by faulty flyback transformers.
Hope I could help.. new here LOL
Happy Fixing =)

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,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

Red and green have separated. is this fixable?


yes this can be fixed
it is the convergence IC's that controls each color image alignment ,also other components(resistors , diodes , capacitors , ect..) in circuit with these convergence IC's(STK's) also need testing to see what other component has also failed or needs replacing.

Sony 65 Inch Projection TV Color Red Green Separation


Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.

Convergence not lining up


Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
