COLOUR BANDING

FLUCTUATING COLOURS
Broken colour wheel and will require replacing. Request an RMA here.

DISCOLOURED LINES RUNNING HORIZONTAL/VERTICAL

YOUR UNIT IS NOT WORKING, AND ONE OR MULTIPLE LED INDICATOR LIGHTS ON THE COVER IS/ARE FLASHING INTERMITTENTLY.
First, identify which LED(s) is/are flashing and how many times.
Second, check the user manual to see if the manufacturer provides information that will help decode the LCD flashing pattern and indicate what the problem is.
If the problem is not a simple one to rectify (e.g. replacement of filter or lamp, etc.), please contact us to help you further or request an RMA here.

ONE OF THE INPUTS (E.G. VGA, DVI, HDMI, ETC.) ON YOUR PROJECTOR DOESN’T APPEAR TO BE WORKING.
First, check to make that the problem isn’t with your output source (e.g. TV, receiver, computer, etc.) – try connecting the projector to a different output device.
Second, If the problem is not with the output device, next, determine if the problem is the video cable – try replacing the video cable.
If the problem still exists, please have your unit sent in for evaluation. Request an RMA here.

Case #5: If you hear a popping noise and your projector doesn’t power up, the lamp may have exploded within the unit. We advise you to only go so far as to confirm this is the case. If the lamp has indeed exploded, DO NOT open up the unit and attempt to clean out the broken glass on your own. Please send in your projector for evaluation. Request an RMA here.
