Section 3: Operation
No Signal
The message “No signal” occurs when there is no source signal detected at the selected
Bad Sync
The message “Bad Sync” occurs when HSYNC or VSYNC are active but the signal cannot be displayed. Such a condition occurs when only one of the two sync signals is present or when either sync signal is unstable or of the wrong frequency. Correct the signal or select another input.
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.
System Warnings / Errors ' 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 Exit from presentation level, but may indicate |
the need for service by a qualified service technician. |
NOTE: System messages appear
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 
to remove the message, but for best results you should reset the
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
with the 
(power) key.
Status Display
If the status window 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 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.
