Using Basic Projector Features
Monitoring and Controlling the Projector
If the No Signal message appears, try the following solutions:
Press the Source button on the control panel and wait a few seconds for an image to appear.
Turn on the connected computer or video source, and press play to begin your presentation, if necessary.
Check that all cables required for projection are securely connected.
If you are projecting from a laptop computer, make sure it is set up to display on an external monitor.
If necessary, turn off the projector and the connected computer or video source, and then turn them back on.
Set the CEC function for the connected device again and restart the device.
If you are projecting from an HDMI source, replace the HDMI cable with the shorter one.
If the other solutions do not solve the problem, reset all of the projector settings using Reset All on the Initial/All Settings menu.
