Use this guide to replace a dirty or damaged lens inside the Epson Powerlite 460 projector.

A lens works by passing light from the projection source through a series of mirrors and then projecting it upwards onto a transparent plate at the top of the machine. The image is then projected onto a screen for display.

A dirty or damaged lens can cause your projection to be blurry or unclear. Use this guide to remove the lens from the projector so you can clean or replace it.

Review the troubleshooting guide; sometimes, a distorted image is the cause of another issue and does not require the lens to be replaced.
