IMAGE STICKING MINIMIZATION (ISM) METHOD-For Plasma TV
A frozen still picture displayed on the screen for prolonged periods can result in a ghost image. You
can use Orbiter to help prevent image sticking. The other two functions are for removing a ghost
image.
Select OPTION.
Select ISM Method.
Select Normal, Orbiter, Color Wash,
or White Wash.
Return to TV viewing.
_ Normal: If image sticking is never a
problem, ISM is not necessary - set
to Normal.
_ Orbiter: To avoid a ghost image on
the screen, the image will move every
2 minutes to help prevent ghost
images. However, it is best not to
allow any fixed image to remain on
the screen.
_ Color Wash: The color block with the
screen moved a little and the white
pattern are displayed. It is difficult to
see the after image on all colors.
Once it has been corrected it will not
be visible in any color.
_ White Wash: White Wash removes
ghost images from the screen. Use
sparingly. Watch the TV normally for
a while before using this feature to
see if the ghost image disappears on
its own.
