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.
  • Screen is bowed or warped.

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 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.

The model number you have selected here does not have magic focus--if you really want a answer post the correct model number.

ok, you have more than 1 post for this set--this model uses two of the STK-392-110 OR 392-150 Convergence chips.

If magic focus will not adjust the picture both chips need to be replaced--about 13 dollars in parts if purchased on Ebay.

Green is not offered to be adjusted since it determines the geometry of the picture--red and blue are adjusted to it.

Let me know how much skill you have and I can tell you how to fix the set--it requires two things--getting at the chips and being able to unsolder and replace them--there may or may not also be some resistors around them that are now bad and need to be replaced.

most shops get 300 or more for this repair--total parts cost if you are able to do it yourself is under 30 dollars.

If this helped you rate this solution as I do this here for free.

Green tint


Go to a channel that is in black and white and turn color all the way off.

Screen should be a black and white or gray color.

If green there is a fairly easy way to adjust--let me know what you find and I will tell you how to attempt the adjustments.

How do i adjust the magic focus?


  • Press "Menu" on the remote select the "Magic Focus" option in the Video menu or press the "Magic Focus" button on the front panel to adjust the convergence of the three picture tubes that create the proper color for the picture. Pressing the button on the TV initiates the automatic adjustment, and accessing the feature through the Video menu allows you to choose automatic or manual adjustment, though the "Automatic" setting must be selected for the button on the front of the TV to begin the process.

    My hitachi 53udx10b was supposedly just serviced but the picture is extremely blue. Have tried adjusting picture to no avail. Help.


    I am going to tell you a simple thing to do to know what your problem may be.

    With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?

    If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)

    I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.

    The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.

    This is called gray scale; picture with color off has to be gray or black and white.

    Before you rate this solution if you have questions make a comment right here and I will advise you.

    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....

    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

    Replace the convergence Ic's with a kit that is available through your local parts distributor

    You must replace all resistors in the kit
    If you are not good at soldering and de- soldering have a local tv shop do it for you

    Good luck

    My convergence adjustment is not aligned


    The fact that the magic focus doesn't work means your convergence ic's are shorted or bad

    They have a kit for this tv it is available through local parts distributors
    If you can't find it locally just Google HITACHI CONVERGENCE KIT

    If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

    If you are not sure about doing this repair you should have your local tv guy do it for you
