Problem
Possible cause
Solution
The color of the image looks
pale.
The input signal type (RGBHV/YUV) 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.
