indicator: The screen images are blurry.
solution: Clean the screen using a soft, clean dry cloth.
Many cleaning solutions can damage the LCD

lined in the
Preface. Try to avoid touching the
screen itself. Even the cleanest hands can leave
oils which attract contaminants.
possible cause: The screen is suffering from burn-in.
indicator: The screen has ghost images, even when it’s off.
solution: This problem is usually associated with external
CRT monitors. Use power saving options (
“Con-
serving Power Through Individual Compo-
nents” on page 3 - 16
) to turn off the LCD. You
can also use a
screen-saver which can help pro-
tect an attached monitor.
