简介

This guide demonstrates how to replace an Epson PowerLite 77c (V11H254220) lamp, part number V13H010L41. The projection lamp is the heart of a projector, as it lights and displays images. If you're experiencing issues involving a dim image, or if the lamp isn't illuminating at all when the projector is on, it's probably time to replace the lamp. Issues with the lamp are typically indicated by a flashing orange light under the power button.

There is mercury in the device’s lamp; therefore, there are state and local regulations regarding disposal and recycling. Do not discard in the trashcan.

Before removing the lamp, be sure power down and unplug the device; allow it to fully cool before beginning.
