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.

Sanyo flat screen tv about 2 yrs old has thin colored horizontal lines down the right side


Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

When we try to adjust red cross, red adjustment will go side to side but not up and down. Red horizontal line is curved instead of a straight horizontal line. Blue can be adjusted up and down and don't...


Thats the classic sign of failed convergence ICs and resistors. You can get the convergence repair kit for your model at www.tvrepairworld.com the kit contains the parts and the Cd with instructions.

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.
