  If there's no light coming from your Vivitek Projector, ensure the power cable is securely connected and that the power source is working correctly by testing it with another electrical device. Restart the projector and check that the Power LED is green. If you've recently replaced the lamp, try resetting the lamp connections. If problems persist, you may need to replace the lamp module. As a last resort, put the old lamp back in and have the projector serviced.

Why does my Vivitek D857WT Projector not respond to the remote control?

  Michelle MitchellAug 25, 2025
  If your Vivitek Projector isn't responding to the remote control, first, make sure you're pointing the remote directly at the remote sensor on the projector without any obstructions. Try turning off any fluorescent lights in the room, as they can interfere with the signal. Check the battery polarity and replace the batteries if needed. Also, turn off other Infrared-enabled devices nearby that might be causing interference. If none of these steps work, the remote control may need to be serviced.
