Input Signal Errors
System Warnings / Errors
'
An input signal error message occurs if you are in presentation level (i.e., there are no
menus present) and have selected an input on which the projector detects a problem.
While menus remain operational and any key press will temporarily remove any
displayed error message, you must resolve the signal problem in order to permanently
eliminate the message.
No Signal
The message "No signal" occurs when there is no source signal detected at the
selected input—both HSYNC and VSYNC are inactive and the screen background is
black. Connect or correct the signal, or try another input.
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.

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 and a related text
message in the LCD Status Display window. 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 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 reported to the manufacturer. You can press

down and up again with the

A system error message indicates that a serious malfunction has been detected and
must be reported to the manufacturer as soon as possible (see Status LED Codes,
below). The projector will no longer operate and must be reset—power the projector
