    What to do if there is no light from my Vivitek Projector?

      Jacob FletcherAug 18, 2025
      If your Vivitek Projector has no light, ensure the power cable is securely connected and that the power source is working by testing it with another device. Restart the projector and check if the Power LED is green. If the lamp was recently replaced, reset the lamp connections. If not, replace the lamp module. As a last resort, put the old lamp back in and have the projector serviced.

      If the lamp in your Vivitek Projector goes off, power surges might be the cause. Try re-plugging the power cord. If the Power LED is on, press the power button. If the issue persists, replace the lamp module. If problems continue, put the old lamp back in the projector and have it serviced.

      If your Vivitek Projector isn't responding to the remote control, first, make sure you're pointing the remote towards the remote sensor on the projector and that nothing is blocking the path between them. Try turning off any fluorescent lights or other Infrared-enabled devices nearby. Check the battery polarity and replace the batteries if needed. If it still doesn't work, have the remote control serviced.
