12 TROUBLE-SHOOTING

This is a checklist to help you pinpoint any problem that may arise. Check
the symptoms carefully if you experience any problem. The cure may be
at your fingertips!
Always check that the ON/OFF indicator on the projector
flashes when a key on the remote control is pressed. This
indicates that the projector is receiving signals from the
remote control.
SYMPTOM

image is
completely
black

SOLUTION
Check if the mains cable is attached properly.
Check that the Power switch is ON.
Toggle the ON/OFF button on the remote control.
Check that the Power switch at the mains inlet is
ON.
The unit may have overheated due to the
ventilation slots being covered while the projector
was in use. Also ensure that the ambient
temperature is within spec. Check the air inlet
filter, as it may need vacuuming (see
Maintenance). Wait until the unit has completely
cooled down before using again.
Adjust the CONTRAST and BRIGHTNESS
settings.
Press RESET, which will remove the pre-
determined settings for the current source, and
make the set-up adjustments again.
Check first that there are no loose cable
connections.
You can try to adjust the image quality with the
CONTRAST and BRIGHTNESS keys.
Try to improve the tuning by accessing TUNE in
the menu system.
