How to Fix a Blurry Picture on a Projection TV After Moving to a New Location

By Nina Nixon

Your projection TV may display blurry outlines and other general fuzziness after you moved it to a new location. It is not uncommon for the picture tubes to become misaligned during a transition. Most projection TV models are built to withstand hundreds of journeys. Manufacturers realize this and typically include picture-setting menus for a quick, no-hassle repair.

Step 1

Allow the TV to run for at least one hour.

Step 2

Press the "Menu" button on the remote control, press "Setup," and then use the "Up/Down" arrow buttons and highlight "Convergence." You may see "Automatic Convergence" instead of "Convergence" based on your model, or if your TV is a new and you are setting it up for the first time.

Step 3

Press "OK" and then wait until converging is complete. It may take up to 10 minutes before the Red Center Convergence or Blue Center Convergence menu appears.

Step 4

Adjust the Red Center Convergence when that menu appears. Press the "Up/Down/Left/Right" arrow buttons to move the "Cross" graphic in the center on top of the "Green Cross" graphic if it is not yellow. Press "OK" when finished.

Step 5

Adjust the Blue Center Convergence when that menu appears. Press the "Up/Down/Left/Right" arrow buttons to move the "Cross" graphic in the center on top of the "Green Cross" graphic if it is not a bright bluish-green/cyan color. Press "OK" when finished.

Step 6

Press the "Menu" button on the remote control and then use the "Up/Down" arrow buttons and highlight "Sharpness." Press "OK" and then use "Right" arrow button to increase the sharpness level.

Step 7

Turn on the Scan Velocity Modulation feature to modify the speed of the electron beam as it travels between the screen's light and dark areas. Press the "Menu" button" and then use the "Up/Down" arrow buttons and select "Advanced Picture Settings." Press "OK" and then use the "Up/Down" arrow buttons, and select "Scan Velocity Modulation." Click the box if that option is not already checked.

Step 8

Press the "Go Back" button on the remote control, and then use the "Up/Down" arrow buttons and select "Video Noise Reduction" to remove static that can cause a blurry picture. Select "Minimum" to retain the detail and sharpness.

Tips & Warnings

  • Check your cable connections; verify that all are correct and secure before you apply these steps.
  • Apply convergence again in a few hours after you set up your TV.
  • Press "OK" during the convergence process if you want to cancel it. Do this before the Red or Blue Convergence Menu appears to return the TV to its old picture tube settings.
