Simple troubleshooting and definition of
Possible cause
1. The projector may be unplugged
2. Check the AC POWER SWITCH on the back of
the projector and see if it is flipped to ON.
3. The AC socket may be faulty
4. The lens cover is not replaced properly
1. You will not be able to turn on the projector within
two minutes after you have just turned it off.
This feature is designed to protect the lamp.
1. The battery might have run out
2. You might have inserted the batteries in the wrong
orientations
3. You may be operating the remote control too far
away from the projector's IR sensor or exceeded
the maximum angle of signal reception ; there
might be an obstacle between the projector and the
remote control or there might be a source of intense
light
near the IR receiver.
4. Ø 3.5mm A wired remote connector might be
connected to the projector's 3.5mm port.
5. The remote control's address is not consistent with
the projector's address.
1. The projector may not be turned on properly or
you have not selected the correct input source.
2. You might not have connected the source device
correctly or the source might not be connected to
the projector at all.
The DVD player is connected to the projector through
component cables (RGB-S or COMPONENT2) and
you have set it to progressive scan.
1. The image brightness, contrast, color and tint
might need proper adjustment.
2. The lamp is due for replacement.
The contrast might have been set too high.
The image brightness might have been set too high.
1. The lens may not be in focus.
2. The temperature or humidity of the projector's
working environment may have changed in mid
operation (i.e. going from cold to warm or dry to
humid), leading to condensation of moisture inside
the projector.
The input signal type (RGB-S/COMPONENT2)
might not have been connected properly
1. The cables might not have been properly connected
or the input device itself may be faulty.
2. If the problem persists, it may also mean the lamp
might be faulty.
The G/Y, R/Pr, B/Pb cables from the input might
have been incorrectly connected to the input.
The temperature inside the projector might have
risen.

before starting it up again
(the projector's STAND BY indicator will turn
blue)
1. Replace new batteries
2. Make sure the batteries are inserted in the right
orientation.
3. Adjust the distance/angle between the projector
and the remote control and try again; if there are
obstacles between the projector and the remote or
source of intense light near the IR sensor resolve
these situations and try again.
4. Remove the wired remote cable or
operate the projector using wired remote.
5. Press the ENTER button on the remote control
followed by the Address button until the panel of
the remote control flashes once
(approximately 5 seconds) and try again.

tint.
2. Replace the projector lamp.
Lower contrast settings.
Lower brightness settings.
1. Adjust Lines focus.
2. Turn of the projector first and wait for the
moisture in the projector to evaporate.
Check to make sure that the connections between
the projector and the input device are correct.
1. Make sure the connector and the input device
have been properly connected; check to see if the
input device is in normal working order.
2. Replace the projector lamp.
Please make sure the input source has been
correctly connected to the projector.
When the temperature inside the projector rises,
the cooling fan will operate at a higher speed to
discharge the internal heat more rapidly.
