How to Fix an Epson Projector That Won’t Turn On

Double check that the wall outlet or socket to which your projector is connected is switched on and working.

There could be several reasons why your Epson projector won’t turn on, including a locked power button, overheating, or even a hardware malfunction.

A quick fix that has worked for many users is power cycling the projector. Here’s how to do that:

  1. Unplug all cables from your Epson projector.
  2. Press the Power button on the projector for 10 to 15 seconds to reset its settings.
  3. Wait for 3 minutes.
  4. After 3 minutes, only connect the power cable to the projector and turn it On. Once it has turned on, only then connect the other cables.

If power cycling does not do the trick for you, here are some more quick ways to troubleshoot your Epson projector that won’t turn on:

Check the Power Connections and Batteries

If your Epson projector AC adapter connection is loose, it won’t establish a proper connection.

First check the power cable. It should be properly plugged in.

Double chec that the wall outlet or socket to which your projector is connected is switched on and working.

Unlock the Power Button

The power button on most Epson projectors has a lock feature that prevents it from accidental shutdown. So, if your projector is not turning on, maybe its power button is locked, which is why it isn’t responding.

To unlock the power button of your Epson projector, press and hold the Enter or lock button on the projector for 7 to 10 seconds.

Alternatively, you can use the remote control to Turn On your projector.

Check Projector Lamp

The Epson projector lamp has a limited life; once it exceeds its life, the projector won’t power on.

Usually, Epson projector lamps last for up to 3000 hours. However, I’d recommend consulting your projector manual to check its lamp’s exact life.

If it has exceeded its life, you will need to replace its lamp with a suitable replacement. It’s recommended to get this done by an Epson service center or a qualified technician.

Prevent Projector overheating by cleaning its Vent

All the latest Epson projectors are equipped with a safety feature that prevents them from turning on when their lamp is too hot.

Make sure your Projector is placed in a place with enough room to escape hot air through the Projector’s vent.

Also, check its vent; if there is any debris or dust, clean it gently with a dry cloth for better air circulation.

Many people overlook the cleaning of their projector’s air filter. If your projector is frequently used, it’s recommended to clean the dust filter at least once a month.

Here’s how to clean your Epson projector air filter:

Unplug the projector from the power source.

Open the air filter cover latch and remove the air filter. See the image below:

The location of the dust filter may differ based on the model of your Epson projector.

Clean the filter thoroughly to remove any dust, and consider using a vacuum for better results.

Remember to always remove the filter from the projector before cleaning it.


If none of the above tips have worked for you, perhaps your Epson projector has a hardware failure.

If its under warranty, contact Epson customer support, and they will repair it for free.
