8. Is the "Status" LED flashing a pattern of yellow and red lights while the "Power"
LED is steady red? This indicates an internal system error that may prevent the
projector from operating. If the problem persists contact a qualified service
technician.
The projector does not respond to the infrared remote keypad...
1. Check to see if the wired keypad works. If yes, check that the correct protocol is
used for that keypad.
2. Make sure there is nothing blocking the transmission path between the keypad
and IR sensor.
3. Check keypad batteries.
4. Keep ambient lighting to a minimum. This may be interfering with keypad IR
transmission.
5. Ensure the keypad has not been disabled for use with this projector. Press
to broadcast to all projectors.
The projector powers down unexpectedly...
1. Check status LEDs for an error code. Refer to Table 3.2 System Error Codes.
2. For each lamp, check lamp hours via RS-232. Replace lamp(s) if necessary.
3. Check that lamp fans #3 and #5 are operational.
4. For each lamp, check lamp hours via RS-232 and that they are fully inserted. If
the projector detects both lamps have failed or not installed correctly (lamp
interlock "open"), it will power down automatically.
5. If this occurs during lamp replacement it could indicate that one of the lamp
interlock is "open" for longer than the allowable 2-minute time frame. Make sure
when you remove a lamp from a compartment during a lamp hot-swap, you
replace it with another lamp (good or bad) to prevent the projector from shutting
down.
The display is jittery or unstable...
1. If the display is jittery or if it disappears and reappears erratically then check that
the source is properly connected and that its signal is of adequate quality for
detection. For example, if the projector scans the default input for a signal to
display, and a poor quality or improperly connected source is connected then the
projector will briefly and repeatedly attempt to display an image. If no source is
connected, the " No signal " error message appears over a blank display. Correct
the source connection.
2. The horizontal or vertical scan frequency of the input signal may be out of range
of the projector. Refer to Section 5, Specifications.
3. The sync signal may be inadequate. Correct the source problem.
4. The input signal type may conflict with the input module. Install/use the correct
module for the source.
5. Pixel tracking, phase, filter, etc. may need more adjustment.
The display is faint...
1. Check the Input Levels options (under Image Settings) and turn the Auto Input
Level to OFF then ON.
2. Brightness and/or contrast may be set too low. Adjust as necessary.
