How to set convergence on Projection TV ' s


I have given an general explanation on most projection TV ' s

  1. Enter the menu on your TV. Use the remote control and bring up the menu.
  2. Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  3. Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  4. Press "Enter." A crosshair pattern will appear on your screen.
  5. 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.
  6. 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.
  7. Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  8. Repeat these steps for all colors.

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!

    There is just three lines that show red, green and blue.


    It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

    What kind of connections are you using?

    If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.

    Convergence not lining up


    Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.
