Most likely there is a strong possiblity that the vertical scan amplifier for the observed colour channel is starting to fail. An experienced TV tech who works on your model type can fix this.

Any fault is fixable. It is a question of the amount you are willing to spend, and the avialability of parts from the manufacture.

Hitachi 43fwx20b Convergence Problems


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Hi,
It is failure of convergence out ICs causing 3-D type picture on screen, you need to replace two big ICs in convergence section on main board.
Click Part Store to see an image of IC as well as price info.

DLP Colors Are Off - Picture Is Mostly Blue and Yellow


You are missing either red drive signal to CRT or you have a cold / fractured solder joint on the television. Also with the set unplugged check with a non metalic object like a ruler or a wooden spoon and start tapping around in the front or back of set and see what happens. See if you can narrow which area of the set has a problem... Good luck future technician.. Happy holidays.. Jay

I have a similar pblm. But your first step is to power on with tv's button. Look into the back through holes and look for 4 green and 1 red LEDs lit. If not there are 3 fuses on the power supply board.Fuses can be easily changed.
next step call service.
