If the image is blurry, adjust the focus ring on the projector lens. Ensure that the projector is placed at the correct distance from the screen and that the screen is flat and clean.
To clean the filter, turn off the projector and unplug it. Remove the filter cover and gently clean the filter using a soft brush or a vacuum cleaner with a brush attachment. Reinstall the filter and cover.
Overheating can occur due to blocked air vents or a dirty filter. Ensure that the projector has adequate ventilation and clean the air filter regularly. If the problem persists, consult a technician.
To change the lamp, turn off the projector and let it cool down. Remove the lamp cover and unscrew the old lamp. Insert the new lamp and secure it in place. Replace the lamp cover and reset the lamp timer in the projector settings.
For optimal image quality, set the projector to its native resolution, adjust the brightness and contrast according to your environment, and use the keystone correction feature to ensure the image is rectangular.
