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.

    We cannot get the color to align. It appears like there is a blue or yellow background around words


    If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
    If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
    You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

    Lookslike the picture is in 3d and when i try ti use magic focus


    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 photos of convergence problems.

    e87380c.jpg
    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

    Yellow and blue color ruins total picture on 50" tv,can't get rid


    lupe0112,

    I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

    Hitachi 53uwx10b Convergence


    You must have the original remote to do complete convergence adjustments. Remote method: Press MAGIC FOCUS button on front panel to start the magic focus. When magic focus is running, press MAGIC FOCUS again. STOP should appear onscreen. Immediately press RECALL or STATUS on the remote (must be pressed before STOP vanishes). The set is now in DCAM (Digital Convergence Adjustment Mode). Manual method: Remove the front grill and access panel or reach around from the back and press the little pushbutton located in the front left corner of the PC board, next to the Digital Convergence Module.
    Once in DCAM, the remote buttons STATUS selects green, 0 selects red and ANT selects blue. 2,4,5 and 6 move the cursor and the thumbstick makes the corrections.Make all necessary corrections and then press PIP MODE. The words ROM WRITE? appear onscreen. Press PIP MODE again to store settings. When green dots appear, press MUTE to return to convergence pattern. Press PIP MODE (ROM WRITE? appears again) and then press PIP CH. This will Initialize the internal sensor data positions. When INIT finishes, press POWER on the TV and convergence is complete.

    TV automatically turns magic focus mode on when the power button is pressed on the remote and even manually.


    I have this problem starting today. Unfortunately, others who have fixed it have done the following.

    * Unplug TV for hours and it worked

    * Buying manual switch to the outlet or surge protector and switch power off that way.

    It appears that I'm in no mood to spend hundreds to get this fixed for hundreds of dollars and just going the Radio Shack route of buying a switch which would probably be more of savings. But needless to say, I hope that is the only problem I have.
