Should a monitor, regardless of whether it is a CRT or a flat-panel LCD, need repair, it
should be repaired only by the manufacturer or an authorized repair shop. However,
before having repairs done, compare the cost estimate to the cost of a new monitor. Most
of the time, the cost to repair a monitor is relatively inexpensive as the problem is typically
common and can be easily and quickly repaired.Caring for the Monitor
Here are some tips you should use for extending the life of a monitor. Most of them apply
to CRT monitors, for obvious reasons, but common sense should be your guide with
any monitor. A CRT monitor should always have plenty of free space and airflow around
it to allow its cooling system to work efficiently.
Never stack anything on top of the monitor or around it. If you do, you may
shorten the life of the CRT by causing it to overheat. The CRT is the most
expensive part of the monitor to replace.(^398) PC Hardware: A Beginner’s Guide
