Solutions When No Image Appears
If no image appears, try the following solutions:
• Press the A/V Mute button on the remote control to see if the image was temporarily turned off.
• Make sure all necessary cables are securely connected and the power is on for the projector and
connected video sources.
• If your device is connected via a video scaler or wall plate, connect it directly to your projector.
• If you connected your video source to the Computer2/Monitor Out port, make sure you set the
Monitor Out Port setting to Computer2.
• Make sure the image being projected is not completely black (only when projecting computer images).
• Press the projector's power button to wake it from standby or sleep mode. Also see if your connected
computer is in sleep mode or displaying a blank screen saver.
• If the projector does not respond when you press any buttons on the projector, an internal error may
have occurred in the projector. Contact Epson for help.
• Press the Menu button. If the projector menu displays, there may be a problem with the connected
video source, cable connection, or port.
• Adjust the Brightness setting on the Image menu.
• Adjust the brightness of your projector's light source.
• Check the Display menu to make sure the Messages setting is set to On.
• If the projector does not respond when you press the control panel buttons, the buttons may be
locked. Unlock the buttons.
• If the projector does not respond when you press buttons on the remote control, make sure the remote
receivers are turned on.
• For images projected with Windows Media Center, reduce the screen size from full screen mode.
• For images projected from applications using Windows DirectX, turn off DirectX functions.
• The projector may not be able to project copyrighted videos that you play back on a computer. For
details, see the manual supplied with your computer.
