x Color is not uniform
• Degauss the monitor.* If you place equipment that generates a
magnetic field, such as a speaker, near the monitor, or if you change
the direction the monitor faces, color may lose uniformity.
x White does not look white
• Adjust the color temperature.
x Monitor buttons do not operate ( appears on the
screen)
• If the control lock is set to ON, set it to OFF.
x Letters and lines show red or blue shadows at the
edges
• Adjust the convergence.
x A hum is heard right after the power is turned on
• This is the sound of the auto-degauss cycle. When the power is
turned on, the monitor is automatically degaussed for five seconds.
* If a second degauss cycle is needed, allow a minimum interval of
20 minutes for the best result. A humming noise may be heard, but this is
not a malfunction.
