Service

Unplug the monitor from the wall outlet and refer servicing to qualified service personnel when :

• The power cord or plug is damaged or frayed. • Liquid has been spilled into the monitor.

• The monitor does not operate normally following the operating instructions. Adjust only those controls that are covered in the operating instructions.

An improper adjustment of other controls may result in damage and often requires extensive work by a qualified technician to restore the

normal operation.

• The monitor has been dropped or the cabinet has been damaged.

• Snapping or popping from the monitor is continuous or frequent while the monitor is operating. It is normal for some monitors to

make occasional sounds when being turned on or off, or when changing video modes.

Do not attempt to service the monitor yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing

to qualified service personnel.

• The monitor has been exposed to rain or water.

• The monitor exhibits a distinct change in performance.
