 WARNING:  Before  you begin any of the procedures in this section, follow  the  Safety Instructions.
Self-Test
Your  monitor provides  a  self-test feature  that  allows  you to  check  whether  your  monitor is functioning properly. If  your  monitor and  computer  are properly
connected but the monitor screen remains  dark,  run  the monitor self-test by performing the following steps:
1.  Turn off both  your  computer  and  the monitor.
2 .  Unplug  the video  cable  from  the back  of the computer. To ensure proper Self-Test operation, remove both  Digital (white  connector) and  the Analog  (blue
connector) cables from  the back  of computer.
3 .  Turn on the monitor.
The  floating  dialog  box should appear on-screen (against  a  black  background)  if the monitor cannot sense a  video  signal  and  is working correctly.
While  in self-test mode, the power LED remains  green. Also, depending upon the selected input,  one  of the dialogs  shown below  will continuously scroll
through the screen.
   or

5 .  Turn off your  monitor and  reconnect  the video  cable; then  turn  on both  your  computer  and  the monitor.
If  your  monitor screen remains  blank after you use the previous  procedure, check  your  video  controller  and  computer, because  your  monitor is functioning
properly.
NOTE:  Self test feature  check  is not available  for S -Video, Composite, and  Component  video  modes.
Built-in Diagnostics
Your  monitor has  a  built -in diagnostic tool that  helps you determine  if the screen abnormality you are experiencing is an inherent  problem with your  monitor,  or
with your  computer  and  video  card.
NOTE:  You  can  run  the built -in diagnostics  only  when  the video  cable  is unplugged  and  the monitor is in  self-test mode.
To run  the built -in diagnostics: 1.  Ensure  that  the screen is clean (no  dust  particles on the surface of the screen).
2 .  Unplug  the video  cable(s) from  the back  of the computer  or monitor.  The  monitor then  goes  into the self-test mode.
3 .  Press  and  hold the 
and   buttons on the front panel,  simultaneously  for 2 seconds. A  gray screen appears.
4 .  Carefully  inspect the screen for abnormalities.
5 .  Press  the 
 button on the front panel  again.  The  color  of the screen changes to  red.
6 .  Inspect the display  for any abnormalities.
7 .  Repeat  steps 5 and  6 to  inspect the display  in green, blue, and  white colored screens.
The  test is complete  when  the white screen appears.  To exit, press  the 
 button again.  
If  you do not detect any screen abnormalities upon using  the built -in diagnostic tool, the monitor is functioning properly. Check the video  card  and  computer.
