How to Fix an Epson Projector That’s Flickering

The flickering problem on Epson projector is usually caused by wrong projector’s settings, eco mode, or loose cables.

A quick solution to fix the flickering issue of your Epson projector is to turn off Eco Mode.

Although Eco Mode reduces power consumption of the projector by up to 30% by lowering the brightness and fan speed of the lamp, its extended use can cause flickering issues.

Here’s how to disable Eco Mode on your Epson projector:

  1. Press the Menu button on your projector remote.
  2. Open Settings.
  1. Select ECO in the right panel.
  2. Select ECO Display option and change it to Off. See the screenshot below:

Your projector still flickering? Check the cable connections, factory reset the projector, and check its bulb.

Check Cable Connection

If disabling Eco Mode did not do the trick, then check all the cable connections to and from your Epson projector. Specifically, check the HDMI cable.

If the HDMI or any cable you are using for video connection is loose, flickering will occur.

Power surges in electrical supply will always cause flickering and blinking problems in projectors.

To solve this, use surge protector power strips, or if you are connecting your projector to the wall outlet, use a wall mounts surge projector.

Factory Reset your Epson Projector

To reset your Epson projector to its default factory settings, follow these steps:

  1. Open your projector Settings.
  2. Select Reset option in the left panel. Next, select Reset All (Factory Default) option.

Note that the interface of the settings menu may differ depending on the model of your Epson projector.

Replace Projector Bulb

If none of the above methods work, then your projector bulb might be the main culprit.

Epson projector bulbs normally last for around 2500 to 3000 hours. After the bulb has passed its lifespan, it will flicker randomly.

So, if your projector bulb needs replacement and the projector is covered under warranty, it should be replaced for free by Epson.

If it is out of warranty, and you want to replace it yourself, refer to this official Epson bulb replacement guide.
