Question about Hitachi 57SWX20B 57" Rear Projection Television

1 Answer

Hitachi 57SWX20B 3D Effect due to green light convergence problem

After working fine for a few years, yesterday upon turning on the TV, the shows looked like they were being broadcast in 3D (my kids' assessment). They thought their favorite cartoons were being broadcast in 3D as part of some special 2/29/2008 Leap Day special. Pretty creative, but wrong.

All 3 colors (red, blue, green) are working, but the green aspect of the picture is curved at the top and bottom of the screen. (I'll attach photos)




Although I've used magic focus in the past, I've never really had to. I used it magic focus this time mode which didn't work (automatic mode). I used magic focus in manual mode (and checked the owner's manual) and realized that the green is "fixed", you can only adjust the blue and red. Manual mode shows what should be a white grid of horizontal and vertical lines--they're white when all three colors are lined up on top of each other exactly. On my TV, the center horizonal line (equator) is white (all colors are lined up), and the center vertical line is white. But the green lines get progressively curved towards the edge of the screen. The vertical green lines aren't THAT bad at the edges, but the horizontal green lines are significantly and progressively curved as they are farther away from the center. If I were to manually adjust the blue and red lines to match, the TV picture would end up looking normal height on the left and right sides of the screen, and pinched (shorter) in the middle.

So I've stumbled onto this website (nice job, FixYa). I entered this basic comment to another problem with the same TV, but while I think the result will be the same (get someone to repair it), the exact problem is different, so I'm going to create a separate problem report. Here's hoping the repair is less than the value of the TV (Someone else currently listed theirs on Amazon for about $650).

    Wow polevaulter, I'm amazed at the quickness of your reply
    and the manual you provided. Following your idea, I used some plastic
    drop cloth material to make the jig. I traced the dots using the red/blue
    lines as they were square and I used a level (like your square) to check the
    pattern. So far so good.



    Where I ran into some trouble was with entering "green touch up
    mode". My remote is CLU-5722TSI (on page 51 of the manual).



    I went into Magic Focus manual mode. Then I pressed the ANT button 5
    times to select 13 x 9 mode. Then I pressed Menu, then Info which is
    supposed to enter green only mode. What it did was turn on a dashed cross
    hair. It looks like the info button instead of representing green mode,
    actually toggles the dashed cross hair. So now I'm stuck again. I
    tried to look at other remote diagrams in the document to see if maybe my
    remote was similar to another one but I couldn't find anything. My remote
    clearly looks exactly like the one in the manual that matches the code printed
    on the remote.



    I'm wondering if there might be another problem. When I ran magic focus
    in automatic mode, and I should have written this originally, it got about
    halfway through. It went through the blue and red, but paused on the
    green adjustments and then displayed an error 5 (a green number 5 displayed on
    the lower right quadrant of the tv screen). A couple more tries resulted
    in an error 4. On page 61 or the manual, it refers me to page 95, but I'm
    not sure how to interpret the description of error 4 on that page. Sorry
    if I led us down the wrong path, it was pretty dumb to leave out this other
    information, but perhaps I need some professional help in checking the
    "Placement of Sensor", doing an "Adjustment check (H / V)",
    and checking some resistors as the 3rd countermeasure indicates.

    same problem here .... just started happending on March 17 2008. Where is the manual that eveyone is referencing?

    I am having the same problem. I however do not have the normal remote though. I just have a cheap one. Is there a way i can adjust it via the bottons on the tv.

  • Anonymous Apr 01, 2014

    Watched for an hour or 2 this afternoon. Turned off TV. About 3 hours later turned on TV and colors were out of alignment. The green was bowed at the top, so I went to Magic Focus to adjust. Green doesn't adjust, but on the Magic Focus grid the green lines were warped.

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

http://home.comcast.net/~leebailey00/Hitachi_DCAM_Manual.pdf

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

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.

Picture of a set that needs the fluid changed.

Magic focas not working in the auto mode, stops half way through the process. what can i do to fix this.


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.

My hitachi ultravision digital 43uwx10bis showing red and green i tried magic focus but it didnt work


All 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.

Common Problem #1) Convergence has gone out

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.

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
