To connect the Epson PowerLite 680 to a SMART Board, use an HDMI or VGA cable to link the projector to your computer, then connect the SMART Board USB cable to the computer. Ensure the SMART software is installed for optimal performance.
Check if the power cable is securely connected and the power outlet is functional. Ensure the projector's power button is pressed. If it still doesn't turn on, check for any error indicators on the projector that may suggest a bulb or internal hardware issue.
Use the zoom lever located on the top of the projector to adjust the image size. You can also move the projector closer to or further from the screen to change the image size.
Turn off the projector and unplug it. Remove the air filter cover and take out the filter. Use a small vacuum or a can of compressed air to remove dust. If heavily soiled, replace the filter. Reinstall the air filter and cover before using the projector again.
Ensure the projector is properly focused using the focus ring. Check that the lens is clean and free of smudges. Adjust the projector distance to fit the screen size and ensure the surface being projected onto is flat and white.
Turn off the projector and allow it to cool. Remove the lamp cover screws, then the cover itself. Unscrew the lamp and carefully pull it out. Insert the new lamp and secure it with screws. Replace the lamp cover and screws, then reset the lamp timer via the projector menu.
Yes, the Epson PowerLite 680 supports wireless connectivity with an optional LAN module. Install the module, then use the EasyMP Network Projection software to connect your device wirelessly.
Ensure the projector's vents are not blocked and clean the air filter if necessary. Check the room temperature is within operational limits. Allow the projector to cool before restarting. If the problem persists, seek professional servicing.
Download the latest firmware from the Epson support website onto a USB drive. Insert the USB drive into the projector's USB port and follow the on-screen instructions to complete the update process.
Verify that the audio cables are properly connected and the volume is not muted on both the projector and the source device. Check the audio output settings on the source device to ensure they are directed to the projector.
