areas.
●Has the lens been stored in the projector?
Images will be out of focus if the position of the zoom leve r 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 page46
●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 page23
●Is the lens soiled?
see page24
●Is the projection light shining at right angles onto the screen?
see page109
●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 page47, 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 page65
●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.
