4. Troubleshooting
Situation
Solution
The activated lens
fi
le does not
correspond with the lens mounted
on the projector.
Activate a lens
fi
le which does correspond with the mounted lens or mount an other lens
which corresponds with the lens
fi
le you want to activate.
Corrupt lens
fi
le.
Delete the lens
fi
le and program correct lens type into communicator under
Advanced/lens parameters and recreate a new lens
fi
le. Tip: perform a “Lens Homing”
before creating a new lens
fi
le. Otherwise, if the lens is removed the existing lens
fi
le
becomes useless. Setup all new lens
fi
les away from the maximum limitation of the lens
zoom. It is possible that the lens
fi
le was originally created at the maximum or minimum
zoom capabilities of the lens zoom.
The
fi
nal lens position lays very
close to the mechanical limits which
disable the motorized lens position.
Position the lens manually, or reposition the projector so that the lens position lies further
away from the mechanical limits, or try to use another lens which range is more suitable.
Setup all new lens
fi
les away from the maximum limitation of the lens zoom. It is possible
that lens
fi
le was originally created at the maximum or minimum zoom capabilities of
the lens zoom. Program correct lens type into communicator under Advanced/lens
parameters and recreate the lens
fi
les.
Disconnected wire units (reference
1 image 4-19) of the zoom motor of
the motorized lens.
Remove the front cover of the projector and check if all wire units at the left bottom of
the lens holder are connected.
Disconnected wire unit, of the lens
zoom/shift signals, from the Signal
Backplane.
Remove the front cover and front dust
fi
lter from the projector and check if the wire unit
(reference 4 image 4-19) is inserted in the Signal Backplane (white plug behind blue
wires).
Malfunction Fan Control board.
Replace the Fan Control board. See "Removing a board in the card cage", page 213.
Malfunction zoom motor of the lens.
Use the local keypad to zoom the image on the screen. If unsuccessful, replace the
motorized lens.
Malfunction Signal Backplane (bad
connection).
Replace the Signal Backplane. See "Replacement of the signal back plane", page 231.
Malfunction SMPS board which
supplies power to the lens.
Replace the SMPS board. See "Replacement of the Switched Mode Power Supply",
page 281.
