TROUBLESHOOTING PROCEDURES
This work package contains general information for troubleshooting the Medium SXGA+ Projection System by user
level qualified personnel. A qualified person is one who is familiar with this manual, the operation of the Medium
SXGA+ Projection System and the hazards involved in its operation and maintenance. The work package provides a
systematic approach to locating and correcting malfunction of the Medium SXGA+ Projection System. Each section is
arranged according to the condition/indication of a problem. The corrective action items have been arranged in order
of complexity, with the simpler actions listed first. Note that troubleshooting causes and actions beyond the scope of
operator level qualified personnel are not included in the WP. If a course of action does not present itself, contact
your supervisor.
The most important step of troubleshooting is to gather as much first-hand information as possible from the personnel
who were present when the problem or failure occurred. Information as to how long the Medium SXGA+ Projection
System
has been operating, what systems were connected, whether any protective equipment or devices functioned,
etc., can also help isolate a problem. Note that if in any doubt about how to proceed, contact your supervisor before
taking action.
WARNING
Tools, equipment, clothing and your body must be kept clear of all electrical connections,
while power is applied to the system
Voltage sources, in addition to being an electrical shock hazard, may also potentially produce
serious burns. Care should be exercised when using hand tools around exposed power
connectors. Never let tools bridge two terminals.
If the circuit breaker does not stay in the ON position when energized, DO NOT attempt to
energize repeatedly. This could cause damage to the surge protector or other components.
Instead, investigate and identify the cause of the problem. Correct the situation before
attempting to energize breaker again.
To avoid electrical shock and damage to the equipment, ensure the power cable is
disconnected at the power source before removing or replacing any cables.
