If dust collects on the air filter, clean it to ensure the best performance from your projector. Dust clogs prevent proper ventilation and cause overheating and damage to the projector. See Cleaning and Replacing the Air Filter.

If the dirt is difficult to remove or the filter is broken, you need to replace the filter. You can purchase air filters (part number V13H134A21) from your dealer or from the Epson Store.

Replacing the Air FilterYou need to replace the air filter in the following situations: After cleaning the air filter, you see a message telling you to clean or replace it

We also provide Epson projector maintenance services, which includes complete cleaning of the inside & outside elements, fans and air filters, lenses as well as testing and restoring projectors to manufacturer settings.

You dont need to remove the pcb. Just use some clean and dry air to blow into the holes where the cable go through. If you use air or gas in cans, make sure to not freeze the panels! If you use a compressor make sure there is no oil or water in the air. Be careful with the nozzle, especially if it is made out of metall.

Start cleaning the spots using a dry, clean, lens-friendly microfiber cloth or wipe, such as this MagicFiber Microfiber Cleaning Cloths or Koala Lens Cleaning Cloth .

After cleaning, turn on the projector and see if the spots are still there. If they stay put, the issue may be more technical and complex than initially imagined.

Warning: The projector lamp becomes hot to the touch very quickly and the light is extremely bright. Keep that in mind when cleaning the projector while it’s still on to avoid burning yourself.

If you like the real-time cleaning feedback but are wary of the projector being too hot to the touch, turn the device off and let it cool for some time. Once the heat has dissapitated, turn on the projector and start cleaning.

Solution: Repairing the LCD is not an option, but you can replace it. Unfortunately, changing the LCD could be expensive. Also, you’d probably require a skilled technician to do the work.

There are three main technologies used for projection – DLP, LCD and LED. DLP (Digital Light Processing) uses a chip made of tiny microscopic mirrors and a spinning colour wheel to create an image. DLP projectors deliver sharp images, don"t need any filters, have a better response time as well as 3D capabilities. The effective lamp life of a DLP projector is only 2000-5000 hours and some people see colour ghosting/banding in some scenes. On the other hand, LCD projectors use liquid crystal displays, have no moving parts and thus are generally less expensive. If you are on a budget a single chip LCD projector is ideal while 3-chip LCDs offer better colour saturation, lower noise levels and work better for movies. However, LCDs require constant filter maintenance and output less contrast. The LEDs in LED projectors have a lifespan of over 20,000 hours. They deliver better colours, have lower power consumption and virtually zero maintenance costs. Also, LED projectors are smaller and generate less heat. Do keep in mind that LED projectors have limited brightness compared to LCD or DLP so they are not recommended if your room has a lot of ambient light.

A 3 colour LCD system uses individual LCDs for red, green and blue. The light from each LCD is combined using a prism to create a final image. It usually offers better quality than single chip LCD or DLP designs.
