Solution
Activate a lens file which does correspond with the mounted lens or mount an other lens
which corresponds with the lens file you want to activate.
Delete the lens file and program correct lens type into communicator under
Advanced/lens parameters and recreate a new lens file. Tip: perform a "Lens Homing"
before creating a new lens file. Otherwise, if the lens is removed the existing lens file
becomes useless. Setup all new lens files away from the maximum limitation of the lens
zoom. It is possible that the lens file was originally created at the maximum or minimum
zoom capabilities of the lens zoom.
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 files away from the maximum limitation of the lens zoom. It is possible
that lens file 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 files.
Remove the front cover of the projector and check if all wire units at the left bottom of
the lens holder are connected.
Remove the front cover and front dust filter 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).
Replace the Fan Control board. See "Removing a board in the card cage", page 213.
Use the local keypad to zoom the image on the screen. If unsuccessful, replace the
motorized lens.
Replace the Signal Backplane. See "Replacement of the signal back plane", page 231.
Replace the SMPS board. See "Replacement of the Switched Mode Power Supply",
page 281.
