Question about Hitachi FDX Series 43FDX10B 43" Rear Projection Television

1 Answer

Digital Array We moved our tv and now we are having a problem with the colors. We were able to align all of the red + signs, but we're having a problem with the blue ones. A few of them are tilted and the analog is only working right to left on some and not at all on others. We can also pick one and it will move another one. Not sure what to do.

The unit needs the convergence ic's replaced.This is a common occurance with this set.It should cost no more than from an honest repair place.This problem was caused from a combo of poorly manufactured parts and vibration.They will probably install a factory mod kit for this unit.

Hello, My main color were out of alignment, as per instruction on manual. I pressed the button for digital array and proceded to align the blue color, then I proceded to align the red color but I could...


The red convergence IC has failed. There are I believe 3 total convergence IC in your tv. The prefix for all three is STK392-xxx. If you can solder you can try and replace yourself otherwise you need a tv tech. With Hitachi's sometimes some critical resistors will change value as well and have to be replaced with exact equivalents. Sorry wish it was an easy solution..

Colors do not line up on my tv ( left side of sreen looks like 3D) digital array "+" are only white on right side.


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 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. And you should be able to get the grid straight.

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 flash 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 fix

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.
