Possible cause
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 (RGBHV/YUV2) 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.
The lamp or the cooling fan could be faulty.
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.

between the projector and the input device
are correct.

device have been properly connected;
check to see if the input device is in normal
working order.

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