Epson PowerLite 4650 User's Guide

To connect the Epson PowerLite 4650 to a computer via HDMI, use a standard HDMI cable to connect the HDMI output on your computer to the HDMI input on the projector. Then, select the correct input source on the projector by pressing the 'Source Search' button until 'HDMI' is displayed.
If the projector is not turning on, check the power cable connections and ensure the outlet is working. Verify that the power switch is turned on. If the projector still doesn't turn on, it may require a lamp replacement or professional servicing.
To clean the air filter, turn off the projector and unplug the power cord. Remove the air filter cover and gently clean the filter using a small vacuum cleaner designed for electronics. Reattach the filter cover and plug the projector back in.
If the image is blurry, adjust the focus ring on the projector until the image becomes clear. Ensure the projector is positioned at the correct distance from the screen according to the user manual. Check the lens for dust or smudges and clean it if necessary.
To change the lamp, turn off the projector and unplug it. Allow it to cool for at least an hour. Open the lamp cover and unscrew the old lamp. Insert the new lamp and secure it with screws. Close the lamp cover and reset the lamp timer through the projector's menu settings.
To perform a factory reset, turn on the projector and navigate to the 'Menu'. Go to 'Reset' and choose 'Reset All'. Confirm the reset when prompted. This will restore all settings to their default values.
To adjust keystone correction, access the projector's menu and navigate to the 'Settings' section. Choose 'Keystone' and use the navigation buttons to adjust the horizontal and vertical keystone settings until the image is properly aligned.
It is recommended to clean the air filter every 100 hours of use and to check the lamp life regularly. Replace the lamp when it reaches the end of its expected life, typically around 3000-4000 hours. Perform a full maintenance check annually.
To update the firmware, download the latest firmware from the Epson support website. Transfer the firmware file to a USB drive. Insert the USB drive into the projector's USB port and follow the on-screen instructions to complete the update.
To troubleshoot color distortion, check the cable connections and ensure they are secure. Access the projector's menu and reset the color settings to default. If the issue persists, try using a different input source or cable. If none of these solutions work, the projector may need servicing.
