14.Lamp and Filter Maintenance

The remote control does not 
operate normally

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. 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 OK 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. 

You are able to turn on the 
projector and access the OSD 
Menu but no picture appears.

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. 

1.  Make sure the projector is turned on 

properly and select the correct input 
source. 

2.  Check the connection between the 

projector and the input device.  

The image is too bright or the 
bright areas are blurry

The contrast might have been set too high.

Lower contrast settings.

The image appears washed out 
or the dark areas appear too 
bright

The image brightness might have been set 
too high.

Lower brightness settings.

The image is blurry

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.

1. Adjust Lines focus.

2.  Turn of the projector first and wait for the 

moisture in the projector to evaporate.

The color of the image looks 
pale  

The input signal type (RGBHV/YUV2) might 
not have been connected properly

Check to make sure that the connections 
between the projector and the input device 
are correct.

The image flashes occasionally

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.

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.

The colors of the projected 
image are out of place (i.e. 
displaying red as blue)

The G/Y, R/Pr, B/Pb cables from the input 
might have been incorrectly connected to 
the input. 

Please make sure the input source has been 
correctly connected to the projector.

The noise from the cooling fan 
suddenly grew louder

The temperature inside the projector might 
have risen.

When the temperature inside the projector 
rises, the cooling fan will operate at a higher 
speed to discharge the internal heat more 
rapidly.

The LED indicator on the 
projector’s front panel is 
blinking in red

The lamp or the cooling fan could be faulty. Refer to the definition of 

1.  During projection, the lamp 

suddenly goes off and the 
picture disappears.

2. The lamp does not turn on 

even when the projector  has 
been turned on.

The lamp might have been damaged; check 
the LED indicator on the rear panel of the 
projector and see if it is blinking in red.

The lamp has reached the end of its service 
life; please replace it.
