OPERATION
Bad Sync
The message "Bad Sync" is displayed when HSYNC or VSYNC are active but the signal can-
not be displayed. Such a condition occurs when only one of the two signals is present, or when
either 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 may be out of the projector's operating range. 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 is.
S
ystem 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 steady red
"Power" LED and a flashing red-and-yellow error code on the "Status" LED. This condition
indicates the need for service by a qualified Runco 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
message indicates that a system malfunction has been detected (see
Status
LED Codes,
below). A system warning message replaces any input signal message and disap-
pears when the input signal status changes. While the projector will remain operational, the
message indicates the presence of a serious problem that should be reported to the manufactur-
er. You can press to remove the message, but for best results you should reset the projec-
tor-power the projector down and up again with the key.
System Errors
A system
error
message indicates that a serious malfunction has been detected and must be
reported to the manufacturer (see
Status LED Codes,
below). The projector will no longer oper-
ate and must be reset-power the projector down and up again with the key.
The Status LED Codes
If the "Status" LED on the back of the projector repeatedly flashes a pattern of yellow and red
light while the "Power" LED glows a continuous red, you have encountered a likely system
error requiring the attention of a qualified service technician (see
System Warnings and System
Errors,
above). Try resetting the projector by powering it off and on again, cooling when neces-
sary. Consult Table 1 and contact your Runco dealer if the problem persists.
The specific pattern of flashing indicates the 2-digit code identifying the type of problem
encountered-the number of yellow flashes represents the first digit and the number of red flash-
es indicates the second digit. For example, a pattern of "yellow-yellow-red-red-red" is "Code
23", meaning the lamp ballast (power supply) is overheated. These codes include:
