Introduction
If your Asus Zenfone 2 Laser (ZE551KL) sounds quiet, produces poor sound quality or has no audio output at all, follow this guide to successfully replace the speaker itself. The Zenfone 2 Laser has a mono rear facing speaker that is used to output audio from phone calls on speaker or media such as music or videos.
Before following this guide, ensure you have the correct Zenfone 2 Laser model as listed here as other variants may not have the same procedure.
Step 1 requires a complete shut down, if the display is damaged and using the normal shutdown procedure (as shown in step 1 of the guide) is not possible, use the following step 2 and step 3 procedure to manually shut down the phone. Although not necessarily recommended to perform an emergency shutdown, this is essential to prevent the possibility of short circuiting.
Short circuiting is when a material (tool or something) creates a connection between two electrical components with lower resistance that causes damage.
