image 4-19) is connected with the Signal backplane.
Replace the Fan Control board. See "Removing a board in the card cage", page 213.
Use the local keypad to focus 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",

Solution
Activate a lens file which does correspond with the mounted lens or mount an other lens
which correspond with the lens file you want to activate.
Delete all current lens files and create new lens files. Note that each time the lens
is removed new lens files has to be created. 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.
Position the lens manually, or reposition the projector so that the lens position lays further
away from the mechanical limits, or try to use another lens which range is more suitable.
