Hi simon
To answer your question;
What you have is called a convergence problem.
Some parts inside will need to be replaced.
If you or a friend feel handy , i will leave you a web address where you can find what you need to repair your tv.
If your set is a Samsung HCM422W (as listed above) then you can follow this LINK to find your parts.
But you will also need a soldering iron and de-soldering tools so i`m leaving you this LINK as well, the kit has everything you need.
Hope this help Cheers

Whys the only colours on my tele are green n pink?


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Call a good TV Tech and have him replace the convergence amp IC's and do a complete alignment. This a $325 job at the most.
Check with your local BBB before you decide on a TV Tech.
