Before contacting your service rep or paying for a costly check-up, try these 5 troubleshooting tips.

1. Check your power: Is the power cord plugged in? Is the main power switch to the projector turned on?  cord. Has it come loose? Check to make sure the power cord is plugged in and the main power switch is turned on if the projector—including the fan, doesn’t operate at all.
2. Check your connections. Is the image source connected to the projector? Are the cables between the projector and computer secure?
3. Check your batteries. If you usually turn on the projector through the remote control, check the batteries.
4. Check your temperature. Your projector has a built-in safety feature that shuts down the projector if it starts to overheat. Check that the filters are clean so air can circulate and keep the projector from overheating and shutting down. Your projector will have a status indicator that will flash if the projector is overheating.
5. Check your lamp. If the projector lamp has exceeded its lamp life, the projector automatically stops working. The Lamp Replace indicator on the projector will be lit up or perhaps blinking. You may also have noticed a change lamp message appearing on screen  (have you been ignoring the message?). Be sure to buy only genuine projector lamps from an authorized dealer.

If you’ve run through this checklist and your projector is still not working, check your manual for further troubleshooting tips and then contact your local repair center.
