Exit Exit

Section 3: Operation

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.

System 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 numerical error code on the status LED display. 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 investigated. You can press 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 Exit Exit 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.
