LG CineBeam Battery Replacement

はじめに

If your LG Cinebeam's (Model# PH150B) works only when plugged in and either dims out quickly or turn off while unplugged, your battery may be faulty. This guide will help you replace the device's battery.

The projector can work while plugged into a power source or unplugged using its rechargeable battery. Its battery lasts around 2.5 hours. The battery is only needed when the projector is unplugged, so it can still work if the battery is faulty while it is plugged in.

When replacing the battery, replace it with a similar Lithium-ion battery with a 7.4V.

You will have to remove the motherboard to access the battery. 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.
