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 projector does not recognize the signal. 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 appears 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
Exit
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 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
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
Exit
from presentation level, or try
resetting the projector by powering it off and on again, cooling when necessary.
Consult Table 3.1 and contact your dealer if the problem persists.
