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.

Screen has red vertical line


This is rare in a newer TV. You prob have an open winding on red yoke, or the problem may be in the convergence circuit. Check for open connections, check for crt burn. Vertical? up and down line??

Please give more info. Sorry I was not more helpful.

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Vertical lines


The red line in the crt is the sreen voltage is to high or bad tube.
A simple fix is if you take off the front panel there will be a black box be careful it is high voltage make sure you are a pro.
there will be six controls look for the one marked screen and is for red tube adjust very slightly counter clockwise.until red
line gos away. If that does not fix it its the red tube.


I hope this helps doctor video
