A horizontal white line on the screen means that you have problem on vertical section. It might be the vertical IC or other components near that IC.

My picture is doubled on my toshiba TN50V71 as if there is a shadow behind everything? Please help!


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!

    Picture Problems: Snow, color, lines


    The most likely cause is shorted convergence chips and possibly a few pico fuses.

    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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
    You can get a convergenece repair kit with instructions from the links 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

    Pink horizontal line when the tv is powered on.


    1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change.
