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.

    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...

    Problem #1) Convergence

    Yours may have one or more of the following symptoms...

    *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

    Problem #2 - Another common problem is dull or washed out video.

    Your set may have one or more of the following symptoms....

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

    Double image on green


    Focus won't help if it is a double image. Sounds like convergence amps need to be replaced. Very typical on these.

    Magic Focus does not work.


    Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
    with upgrade Stk394-160E Hitachi part # CZ 01341,change both
    for reliability.....check B+ feed resistors for over-heating....T.

    Hitachi 43FDXO1B Convergence?


    Manual Convergence for the Hitachi. YOU WILL NEED ORIGINAL HITACH REMOTE CONTROL. NONE ELSE WILL DO.
    1. Receive an NTSC signal.
    2. Press Magic Focus to begin magic focus
    3. Press magic focus again during the magic focus process to get the “stop” screen.
    4. While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and the service grid (64 point grid).
    5. When you first get in here? I believe red is the selected color by default (it is flashing).
    6. To choose other colors to converge, use the following buttons on the R/C:
    · “STATUS” - Green
    · “0” - Red
    · “ANT” – Blue

    7. Start from the center of the screen and work your way out on one color at a time. I adjusted red across the whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
    may want to go back and adjust some red again? etc. until the convergence looks good.

    · Use 4, 6, 2, and 5 on the R/C to move the cursor position (dotted lines).
    · Use thumb stick to move the convergence point color.


    Then going along the lines and adjusting, you may run into the problem of getting an ‘S’ curve on the line. You’ll know if you get there. Basically, no matter what you do to adjust the line to be converged, the middle of the line between the points will not straighten out (it bends between the points). To fix this, the manual recommends going to the (7x5) mode which gives you less points to adjust. I had this problem, and the solution worked. There is also another mode (3x3) which gives you even less points. Basically, if the set looks good, you only fine tune it in (13x9) mode (64 point). If you have serious problems, the grids work as:
    3x3 – ‘coarse’
    7x5 – ‘medium’
    13x9 – ‘fine’
    10) To get to each of these patterns use the following on the R/C: (only if you need to)
    1. (3x3) Press “STATUS” 5 times (only works when DCU is in uncorrected state)
    2. (7x5) Press “0” 5 times
    3. (13x9) Press “ANT” 5 times
    11) If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point… depending on where you start, work your way up, and always finish on the 13x9
    12) When finishing up the 13x9 mode, to get additional ‘grids’ on the edges of the screen, press the PIP CH button on the remote control while in the digital convergence adjustment mode (DCAM). Fine tune the edge convergence as necessary. To exit, press PIP CH again.
    13) When convergence is acceptable, press PIP MODE to write data to ROM memory. ROM WRITE? is displayed to alarm system that ROM will be overwritten with new data. Press the PIP MODE button again to write displayed data to ROM.
    14) DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
    15) Green dots will be displayed when operation is completed.
    16) Press MUTE to return to convergence pattern, then confirm again convergence is acceptable.
    17) Turn power OFF.
    18) Wait a few seconds. Turn the TV on, and you should have your normal signal. Press Magic Focus button just to make sure the magic focus still works (and that you did the last few steps properly)
