– Solutions
– Plug the power cord of the projector into the AC outlet.
– See if the POWER indicator lights red.
– Wait until the POWER indicator stops blinking to turn on the
projector again. The projector can be turned on after the POWER
indicator turns red. (See page 20)
– Check the WARNING indicator. If the WARNING indicator lights
red, the projector cannot be turned on. (See page 57)
– Check the projection lamp. (See page 60)
– Unlock the Key lock function. (See page 53)
– Make sure "Off" or "Countdown off" are not chosen at display
function.(see page 47)
– Make sure "User" or "Off" are not chosen at Logo (select) as the
default set. (see page 48)
– Make sure Input search function is adjusted properly. (See page
46)
– Adjust the focus of the projector. (See page 23)
– Provide proper distance between the projector and the projection
screen. (See page 13)
– Check the projection lens to see if it needs cleaning. (See page 59)
– Moving the projector from a cool to warm place may result in
moisture condensation on the projection lens. If this occurs, leave
the projector off and wait until condensation evaporates.
– Check the connection between your computer or video equipment
and the projector. (See pages 15-17)
– See if the input signal is correctly output from your computer. For
some laptop computers, you may need to change the setting for the
monitor output when connecting to a projector. See your computer's
instruction manual for the setting.
– It takes about 30 seconds to display an image after turning on
the projector. See if the selected system is corresponding to your
computer or video equipment. (See pages 27 and 39)
– Select a correct input source once again through menu operation.
(See pages 26, 37 and 38)
