Aligning the video image on a rear-projection television set is necessary to acquire a clear, focused picture. All CRT televisions, including big screen models, are designed to project a video image onto the screen using three picture tubes. Each tube projects its own color -- red, green or blue. All three images have to converge correctly to provide a clear video image. If they don't, the picture becomes distorted and out of focus.
Instructions
1. Press the "Menu" button on the remote control and press the right directional key to access the "Picture" menu. Scroll down using the directional button to locate the "Manual Convergence" option. Press the right directional button to enter the "Manual Convergence" mode.
2. Press the right direction button to access the red tube and press the down direction button, then the right direction button to access the blue tube. If the out-of-focus picture has a blue outline, the blue tube needs to be adjusted. If the outline is red, the red tube needs to be adjusted. The green tube is not adjustable and is used as a constant to align the other tubes against.
3. Press the direction buttons to move the cross hair until the outline of the cross hair is white. Press "Menu" to save the changes and enter the "Manual Convergence" menu. Press "Exit" to get back to the standard video screen and verify the picture quality. If the image is still unfocused, adjust the "Multipoint Convergence."
4. Repeat Step 1 to enter the "Manual Convergence" menu then press the down directional button to select the "Multipoint Red" if the picture is still showing a red tint. Select "Multipoint Blue" using the directional buttons if the out-of-focus image has a blue shade. Scroll to any cross hairs that have a color outline and press "Exit" to adjust it.
5. Press the directional button until the color outline of the cross hair is gone. Press "Exit" to move to any other cross hairs that are misaligned. Select and adjust the remaining distorted cross hairs until they all have been corrected. There are 35 cross points on the television screen. Press "Menu" then scroll down and select "Save Multipoint" to save the adjustments.
