Hitachi 43FDX15B Convergence Failed

My 43FDX15B has a failed convergence with the red CRT.

I am amateur level at soldering... but I have repaired a TV before (replaced IR receiver on a Philips 19" TV 15 years ago).

What is required to repair this set?
How difficult is it?
What would a shop charge to do it (reasonable rate)?
What is the TV worth now?

Thank you!

You will need to order part no. CZ01341. This is the output ic. There are 2 of them, replaced them both. The numbers that are printed on the old part will not match the new part, do NOT take this to hart. It is a modification that you are putting in. You should be able to do this your self. I would charge 350.00. The set is not worth much, not working. Maybe 100.00

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

The picture has colored shadows and doubled images. People are doubled shadows are red green purple. I would like to know if it worth fixing the tv is about Ten years old. Thank You


In a nutshell, the convergence ICs have failed. The cost to fix by a service company is likely about $300. You may find someone who does it on the side for around $150.

If you are happy with the picture, you like the tv, then $150 might be worth it.

It is possible to do this repair yourself if you have an electronics background.

Hitachi 43FDX15B distorted picture. The top of screen displays a half circle cirle and the image is distorted within the half circle. The same at the bottom of the screen. The middle of the screen is fine....


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.

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 from the link below.

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 - 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.

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 solution

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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Hitachi projection TV - video is in 3d rainbow


This sounds like a convergence circuit problem. Your set has two convergence IC chips (integrated circuit). One is for the red CRT, the other is for the blue CRT. This is a common issue with projection TVs. It is not a difficult repair if you have any experience with electronics and soldering. Both convergence ICs should be replaced at the same time. The part is IC (STK394-160E) and is available for around $36 or less. If you have a shop fix this they will likely charge $300-$400. If this information was helpful or if you would like to know how to do this repair in more detail post back on this thread. I would be happy to walk you through it.

I have a Hitachi 43UWX10B that won't turn on. When I try, the red power light flashes, and I hear intermittent chirping. Any way to verify the problem and estimate repair costs?


Your convergence chips have failed.

Sometimes when they fail the TV will look 3D or distorted and sometimes it will just loose video and audio and chirp.

This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly. 4) TV Chirps

sounds like the convergence is out of whack. you will need to call a local repair shop and see if they can realign the color guns inside the unit. this is actually a really common problem with moving a rear projection screen.

Can't get the blue and red box to align


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Double IMAGE of RED


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
