LG CineBeam Wi-Fi and Bluetooth Card Replacement

Introduction

The LG Cinebeam's (Model# PH150B) contains a Bluetooth card which allows it to connect to Bluetooth. If your device is having trouble connecting to Bluetooth or can't be detected, you will have to replace it.

Bluetooth allows you to wirelessly connect your projector to another device such as a speaker.

Before replacing the Bluetooth card, make sure it is broken by connecting it to multiple devices and seeing if any of them work. If none of your devices are able to connect to the projector but are able to connect to another device, then your Bluetooth card is likely broken.

You will have to remove the motherboard to access the Bluetooth card. While removing it, make sure to use caution while replacing the ribbon cables as they could rip.

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