4 Troubleshooting
4.1
OVERVIEW
The CP2230 offers a comprehensive system of diagnostics, tracking a wide range of conditions and alerting the
operator to a potential problem by display specific status information at the Touch Panel Controller (TPC) or
by the available internal or external LEDs.
This system includes:
TPC Status Menu
TPC Alarm Windows
External Projector Status LEDs
Internal PCB-specific LEDs and Main AC status LED
If warnings and errors reported at these locations cannot be resolved by the operator or administrator, further
troubleshooting by a Christie authorized service technician may be required. When troubleshooting, keep in
mind that the projector is comprised of numerous replaceable modules, such as printed circuit boards, optical
assemblies and power supplies. This modular design can reduce the amount of time required to accurately
diagnose and resolve a performance issue — the cause need only be traced down to the module level, at which
point the faulty module is usually replaced. No further analysis is necessary.

TROUBLESHOOTING
This section provides troubleshooting procedures that can help direct you to the most likely cause of a specific
performance problem. Refer to this section if you cannot eliminate the problem through proper adjustment of
the projector. Note the symptoms present and work through the appropriate troubleshooting steps to determine
the source of the problem. For more information on troubleshooting a displayed image, refer to the product’s
User Manual

4.2.1 Projector Does Not Power ON
1. Check the wall circuit breaker to see if it’s ON. If there is a
problem with the wall circuit breaker “tripping” OFF, have a
certified electrician investigate any electrical problem.
2. Check the status of the LEDs on the rear corners of the projector.
(
Figure 4-1
). If there is no activity, see #3.
3. Verify power by looking through the rear, right side grill. One
LED should be present in the upper right. This indicates the
LVPS has power. Another LED should be seen in the lower left
indicating Main input (
Figure 4-2
).
