LG CineBeam Motherboard Replacement

Inleiding

The LG Cinebeam's (Model# PH150B) motherboard recognizes the inputs for the projector, so if your device doesn't recognize the inputs, you should replace it.

Typically, the motherboard doesn't break easily when the device is closed. However, when opened, be careful as you could damage it or one of its parts.

Removing the motherboard also grants access to the other parts of the projector. This guide will help you through the process of removing the motherboard.

Before beginning, make sure to power off the projector completely and disconnect from any external power source.

When done, make sure all the cables/wires are placed correctly and secured.
