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.

hi, sounds like a convergence issue. try this...
  • Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

  • Enter the menu on your TV. Use the remote control and bring up the menu.
  • Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  • Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  • Press "Enter." A crosshair pattern will appear on your screen.
  • Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  • Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  • Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  • Repeat these steps for all colors.
    good luck!

    4.14.1 Understanding Viewing Features
    Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
    You can switch viewing modes using the remote control.
    4.14.2 Viewing Modes
    Normal Mode
    The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
    added to the left and right of the display image. Standard TV broadcasts are
    displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
    to as pan-and-scan or full frame. These movies were originally filmed in 16:9
    (widescreen), and then modified to fit a traditional TV screen (4:3).
    Wide Mode
    When watching a standard broadcast or full-frame movie in this mode,
    the display image is stretched proportionately to fill the TV screen.
    When watching a widescreen (1.78:1 source) program or movie, the
    display image fills the TV screen. If you are watching a widescreen
    (1.85:1 or 2.35:1 source) program or movie, there will still be black
    bars at the top and bottom.
    Zoom Mode
    When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
    program or movie, the display image is zoomed proportionally to fill the
    width of the screen. The top and bottom are cut off to remove most of
    the source material’s black bars. This mode is good for programs or
    movies with sub-titles.
    Panoramic Mode
    When watching a standard broadcast or full frame movie in this mode,
    the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
    horizontally on the left and right sides to fill the TV screen. The center
    of the image is not stretched.

    Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
    mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
    will return to widescreen.

    PICTURE HAS DISTORTED HORIZONTAL LINE IN CENTER OF SCREEN.


    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.

    Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

    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 - TV may also make a chirping noise.
    Here are some photos of convergence problems.

    49abec3.jpg
    f0add3d.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.

    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 solution

    93a1209.pngCONVERGENCE SOLUTION

    You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
    This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com
