How do I Troubleshoot an Epson EMP-X5 Filter?

Updated February 21, 2017

The Epson EMP-X5 multimedia projector uses a high-powered lamp to display an image on screen. To keep the lamp cool, the projector has an internal fan system. Since the fan moves air, an air filter is necessary to keep dust out of the projector. If the air filter gets clogged, the projector can begin to overheat. As the projector overheats, the fan must work harder and may eventually burn out. If your EMP-X5 is overheating, do a bit of troubleshooting on the air filter to prevent more serious damage down the road.

Check the warning indicators. The EMP-X5 has a series of lights on the front of the device that tell you if the projector is experiencing trouble. If the two outside lights are glowing red, the projector is overheating. Turn off the projector and unplug it from the electrical socket. Let it sit for at least an hour before turning it back on.

Clean the air vents. Your air filter may still be working, but if the air vents leading to it are dirty, it doesn't matter. The air vent is located in the corner of the projector's base. Use a small hand vacuum or a can of compressed air to thoroughly clean the vents.

Remove the air filter. The air filter is located underneath the air vents and can be removed without opening the projector. Stick a finger in the recessed tab on the end of the filter and slide it out of the projector's base.

Clean the air filter. Wash the air filter with warm water and allow it to air dry completely. When dry, slide the air filter back into the projector.

Examine the air filter for physical damage, such as holes or tears, If cleaning the filter did not help. If the filter is damaged, replace it.

Purchase a new air filter from Epson. Slide the new air filter into the slot in the projector's base.

Contact Epson customer support. If your projector is still overheating after replacing the filter, the problem is likely the fan instead. Contact Epson customer support at its website to get your projector repaired.


Clean your air filter monthly to prevent damage to your projector from overheating.
