Aligning the convergence With a the key (I), the 2 screws (H) can be loosened from the top. This is a critical action: the crews have to be loosed so that the LCD can be moved with some friction. Now clamp the manipulator over the LCD panel. With the manipulator the LCD can be moved into the correct position. If the movement is too light or too difficult, readjust the tightness of screws (H). Adjustment can best be done in the following order. Lift the LCD up, so that the picture is below the original picture. Now rotate the LCD, so that the vertical lines are parallel to the vertical lines of the original. Now adjust the picture left/right, so that the sides match the sides of the original. Now carefully push the LCD panel down, keeping the sides parallel, until the picture is correct. If you do not get the required result, sometimes a small correction can be done, but otherwise it is better to start over again. If the convergence is within specification (< 1 pixel), carefully fix the screws (H), to fix the LCD. If necessary fix the LCD with some glue or lacquer, before fixing the screws.
