Information Regarding Convergence
In the projection television, the image is formed by
projecting 3 different color images (red, green and blue)
onto the projection screen. Convergence refers to the
alignment of red, green and blue images on the
projection screen. When these images are properly
aligned (converged), you see a sharp and vibrant color
image. Sometimes, the three images may require
alignment. This is due to the effect of earth’s magnetic field
on the projection tubes. Normally, adjustment is not
necessary after the initial alignment at the center of the
screen. It is possible to correct the color fringing on other
areas of the screen by using the buttons on the remote
control and by following the on-screen instructions in the
set-up menu. Please converge the images before using the
television for the first time. The following diagram shows
examples of a misaligned image and a properly aligned
image. Please refer to pages 28 and 29 for detailed
procedure on how to adjust convergence.
Make sure that the set is on for at least 20 minutes
before adjusting convergence as described on pages 28
and 29.
Convergence adjustment is independent for each format
(480i, 1080i or zoom). Setting in one format does not
affect the other.

WARNING: The marking or retained image on the
picture tube resulting from viewing fixed image is
not an operating defect and as such is not covered
by Warranty.
The projection television is designed to display
constantly moving images on the screen. Continuous
viewing of stationary images such as letterbox pictures
on standard screen TVs (with top/bottom bars), non-
expanded standard (4:3) pictures on wide screen TVs
(with side bars shown on each side of an image), stock
market report bars (ticker running at the bottom of the
screen), video game patterns, fixed scoreboards,
bright station logos, on-line (Internet) or repetitive
computer style patterns should be limited.
The extended use of fixed image program material can
cause permanent picture tube damage, shown as a
“shadow image” viewable on normal programs. This
type of irreversible picture tube deterioration can be
limited by performing the following steps:
Limit the display of fixed image program material to
no more than 15% of total viewing time per week.
Turn the power off when not in use.
