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 display. A system
malfunction can be cleared with
Exi t
Exi t
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
Exi t
Exi t
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.
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
Exi t
Exi t
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.
