Section 3: Operation
Other Signal Error Messages
In addition to the common "Bad Sync" and "No Signal" errors, you may encounter a signal
error message indicating that HSYNC and/or VSYNC are either too fast or too slow. When
such a message appears, check the frequencies shown in the Status menu. If they are
correct, then the signal is not recognized by the projector. On some PCs you may be able
to change the settings to generate a compatible signal. If the frequencies shown in the
Status menu are incorrect, check the cabling to see where the problem might originate.
When the projector encounters a system malfunction, either a System Warning message
or a System Error message may appear. Both types of messages are accompanied by a
numerical error code on the status LED display. A system malfunction can be cleared with
Exit from presentation level, but may indicate the need for service by a qualified service
technician.
NOTE: System messages appear on-screen only if Display Error Messages has been set
to "Screen" or "All".
System Warnings
A system warning indicates that a system malfunction has been detected (see Status
LED Codes, below). A system warning message replaces any input signal message
and disappears when the input signal status changes. While the projector will remain
operational, the message indicates the presence of a potentially serious problem that
should be investigated. You can press Exit to remove the message, but for best results
you should reset the projector—power the projector down and up again with the (power)
key.
System Errors
A system error message indicates that a serious malfunction has been detected and must
be investigated as soon as possible (see Status LED Codes, below). The projector will
no longer operate and must be reset—power the projector down and up again with the
(power) key.
The Status LED Codes
If the status code display on the back of the projector shows one of the following values,
you have encountered a likely system error requiring the attention of a qualified service
technician (see System Warnings and System Errors, above). Acknowledge and clear
the error with Exit from presentation level, or try resetting the projector by powering it off
and on again, cooling when necessary. Consult Table 3.5 and contact your dealer if the
problem persists.
The specific code number identifies the source of the error detected, and is particularly useful
in cases where the projector is far away. For example, the code "27" means the lamp could
not be turned on. Error codes for this projector are listed in Table 3.5.
