      Hi Jude,
      The blinking blue light can mean a number of things: POWER: Solid blue/TEMP/LAMP: Blinking red — your lamp needs replacing. POWER: Solid blue
      TEMP/LAMP: Blinking blue — the projector is overheating. POWER: blinking blue: 1. If the Power Saving Mode is off, the
      projector is plugged in or the he projector is powering down and the fans are cooling the projector. If the projector is overheating check that your filters are clean so air can circulate. If your lamp has reached end of life then replace it with an authentic OEM lamp. Hope these suggestions help.

      Hi Bryan,
      The first thing to check is that you have reset the lamp timer and that is has been reset to zeo. Otherwise the projector will think the lamp is still outdated. To reset: navigate to the Advanced Menu > Status/Service menu and select Reset Lamp Hours…A blinking blue light means the fans are not working and should be cleaned.
