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 is.
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
service technician.
NOTE: System messages appear on-screen only if Display Error Messages has been
set to "Screen" or "All".

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 disappears 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 manufacturer. You can press

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 necessary. Consult Table 3.3 and contact your
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 flashes 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 are listed in Table 3.3.
