Question about Hitachi 43FDX01B TV

1 Answer

Top left corner double picture red and green

The top left quadrant of the tv has drooped down about 1 inch with red and green. I held the convergence button while pressing input on the remote to bring up the "secret grid" and in the top left corner the red doesn't move properly and the green doesn't move at all. is this fixable?

    Thank you for your response but, where exactly inside can I find this IC resistor?? I removed the front and rear panels off, exposing all the circuit boards and lenses and can't find anything burned out.

    Ok I found 2 ic's... STK392-110. They appear to be fine, but what do i know. Could it be something else???

You have a failed IC resistor usually you can physically see the bad one because it burns out leaving you to guess what the value was. Hitachi offers a convergence fix kit which has 2 IC's and all approiate resistors.

    the IC's will look normal but they need to changed I assure you of this as far as the resistors go they get grey when they are bad. they should be green with colored stripes on them. if in doubt call an expert in it will cost between 200 and 300 dollars to fix

Picture seems sunk in and the color distorted with doubleing effe


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 projeciton 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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

Part disclored picture


as it has fallen on the floor

due to that its deflection coil position might  have  changed a little.

due to that its left corner has gone down.

 

deflection coil has convergence magnet on it so due to that there is change in color also.

 

please call tech to re position of deflection coil every thing will be fine as it was.

as per buying another it is up to you.

hope this will help.
