Introduzione

The front remote sensor on the Epson PowerLite 77c (V11H254220) is a crucial component if you often use the remote to control the projector. Replacing the remote sensor will ensure the projector can continue to be controlled from a distance using the remote, rather than manually. This component may need to be replaced if the batteries in the remote are new and installed in the correct orientation, but the projector isn't responding to the remote's input. If possible, test your remote with another compatible projector to rule out remote failure before proceeding.
