Check

• Is the power plug connected to the power outlet?

• Is the lamp cover correctly installed?

• Is the internal temperature too high? A protective feature prevents the
power turning on when the internal temperature is too high.

• Has the lamp usage time exceeded 1100 hours? The power will not turn
on when 1100 hours have elapsed.

• Has the connected input been selected?

• Is the cables correctly connected to the input terminals?

• Are the brightness and contrast set to minimum?

• Is the sliding lens cap closed?

• Is the lamp blown?

• Has the lamp usage time exceeded 1100 hours?

• If a notebook type computer is being used, was the computer power
turned on after the projector was connected? Is the computer set to
disable output to the external COMPUTER input terminal?
In many cases, when a notebook type computer is connected to the
projector, a signal will not be output to the COMPUTER input terminal
unless the computer power is turned on.

• Does the STATUS indicator blink?

• Is installation correct?

• Was the Keystone adjustment performed correctly?

• Is the lens properly focused?

• Are the screen and projector positioned at the correct angle?

• Does the projection distance place the screen outside the focus range?

• Is there condensation, dirt, etc., on the lens?
Condensation on the internal optical system is possible when the
projector has been stored in a cool place and then is used in a warm
place. In such cases, wait several minutes for the condensation to
evaporate.

• Correctly adjust the horizontal and vertical position of the screen.

• Is the clock frequency correctly adjusted?

• Are the resolution and frequency correct for the input signal? Check the
resolution of the personal computer.

• Does the send indicator (LED) light? If it does not light, the batteries are
exhausted. In such cases, replace with fresh batteries.

• Is there any obstacle between the remote control and the remote sensors
of the main unit?

• Is the remote control being used outside its effective range?

• Is there a fluorescent light or other strong light source close to the remote
sensors?

• Is the MOUSE terminal of the main unit and the personal computer
correctly connected?

• Was the personal computer started after being connected to the MOUSE
terminal of the main unit?

• Check the STATUS indicator list.

• Manually adjust the clock frequency and phase.

• Press the AUTO SYNC button.

The lamp usage has exceeded 1000 hours of operation and should be

replaced.

• The lamp cover is not correctly attached. Replace it correctly.

• The temperature protector has been triggered. If the room temperature is

high, move the unit to a cool location. If the temperature within the unit is

high, check the cooling fan (exhaust vent) and the cooling fan (exhaust

vent) on the bottom of the unit. If any of the slots are blocked, remove

whatever is blocking them.

Wait at least one minute before turning on the unit again. If this does not

solve the problem, please contact your dealer.
