BenQ Projector Not Turning On: Troubleshooting and Solutions

If you just bought a projector and use it for the first time, you can check the lens cover. If the lens cover covers the lens, the projector’s light may be blocked, and therefore you can’t see the image.

Check the indicator light of the BenQ projector. If the indicator is not lit, then the power cord or the power supply may don’t work. You can try the power socket by testing it with the other electric device, for example, a computer.  If the power is connected, the power indicator light will be green. You can unplug all the connected cables and reconnect them again to see whether the projector can turn on as usual.

If the BenQ has a built-in battery, you can check the battery to see whether the battery is drained. When you have access to the power socket, you can charge the projector and try again when its battery is normal.

Check whether the lamp light is on after turning on the projector. If the lamp light is faint and dark, the projector lamp has reached its end. You can replace a new lamp for the projector and reset the lamp timer.  You can check the lamp timer after long-term use and prepare a new lamp beforehand.

Most BenQ will stop working to protect the projector components from overheating when the projector is overheated. You restart the projector when the projector cools down. To avoid overheating, you should never cover the projector with a cloth or other decorative covering or place sundries around the projector. In addition, you need to turn the projector off when you are not going to use the projector to avoid lamp life waste and overheating caused by long-term standby mode.

Check whether the projector is in sleep mode. If the projector is in sleep mode or sleep timer, you can turn on the projector manually.

Check whether the A/V signal is restricted or disconnected. If the input source, for example, a computer, has been inactive for a long time, the signal may be restricted or disconnected. You can check the working status of the two devices. You can also restart and reconnect the two devices.

Some BenQ projectors support power button locks to prevent their kids from using the projector. You can press and hold for a long time to turn on the projector.
