Not that bad to remove

As long as it is unpluged you won't get shocked

Look to the right of the boards Remove all the little screws from the convergence board
Make sure you mark or notate where the correctors go

Flip up the little connectors to the left of the board
Do not force the board up if you have to force it you missed a screw

use solder wick and remove the parts

make sure there are no shorts and you replace all the resistors in the kit

Good luck

Thee green on my Hitachi 43fdx20b has gone wacky, ive seen an answer to if the red and blue go wierd but not the green. What can I do to save my t.v.?


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. Repair kits with instructions are also avail from www.TvRepairKits.com

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.

Projection sets have two very common problems.

The first common problem is convergence


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,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

My tv has a bow in it every time a banner comes across


It is not unusual in these sets for things not to be perfectly straight---if the set has recently been repaired for a Convergence problem--someone may not have adjusted it correctly.

Understand: if it is a 43uwx10b Hitachi:

The green convergence is adjusted first for a grid of straight lines up and down and left/right---if the green grid is not straight you are going to see a bow when things scroll across the screen.

The other possible problem you may have is a convergence problem--if you go into the customer menu and try to adjust convergence--not the magic focus-- are the blue and red adjusting or not?

I know the HItachi sets very well--I own two of them and have repaired hundreds of them.

Let me know if you have more information or need advice--I am here to help people.

Your TV most likely has a problem in the convergence circuits. ( 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

convergence fail. replace convergence ICs with stk-392-110 can be accessed through the front. take off the speaker grill and panel behind that. there will be a large heat-sink under the picture tubes that is the convergence power board. disconnect all cables(mark any that look the same) going to and from that board de-solder the amps --- replace any burnt or open resistors--- plug everything back in turn the tv on and adjust any alignment needed in the regular tv menu.
