The monitor makes a sound
when it is turned on.
This is normal as some sound may be generated when the metal
case and the electromagnet, which are installed to block any
electromagnetic waves, interact with each other.
How can I clean the outer
case/Picture tube?
Disconnect the power cord and then clean the monitor with a soft
cloth, using either a cleaning solution or plain water.
Do not leave any remains of the detergent nor scratch the case.
Do not allow any water to go inside the monitor.
