The image is unclear
· The screen is 
blurred.
· Focus can only be 
attained in certain 
areas.
Has the lens been stored in the projector?
Images will be out of focus if the position of the zoom lever is outside 
of the [W] to [T] range. Ensure that the lever is set within the [W] to 
[T] range.
Has the focus been set correctly?
see page 46
Has the projection angle been increased by adjusting the feet?
There are cases where the vertical focus is difficult to align if the 
projection angle is too large.
Is the projection distance suitable?
The recommended projection distance range is between 1.1m and 
13.9m. Locate the projector within this distance range.
see page 23
Is the lens soiled?
see page 24
Is the projection light shining at right angles onto the screen?
see page 109
Is the lens fogged?
Condensation will form on the surface of the lens when the projector 
is suddenly brought into a warm room from a cold room, and this 
may lead to the image seeming blurred. In this event, switch the 
power off and leave the unit to stand for a while.
Has the [Sync., Tracking and Position] been adjusted?
The image can be adjusted by regulating the [Tracking] and [Sync] 
buttons on the projector while monitoring the image on screen. 
Adjustments can also be made by opening the [Menu].
see page 47, 65
Has the signal format setting for the image been set correctly?
Set the signal format with [Menu] 
− [Image] − [Video Signal]. There 
are cases where the image signals being input cannot be determined 
in the [Auto] mode.
see page 65
Do the input signals match the connected equipment?
Set the signal type with the [Menu] - [Image] - [Input Signal] 
parameter. Set [RGB] for computer signals, and [YCbCr] or [YPbPr] 
(depending on the equipment signals) for component video signals.
