Einleitung
The InFocus LP540 Projector is intended to provide clear audio. If your InFocus LP540 Projector produces distorted, intermittent, or no sound, use this guide to understand your audio problems and determine if replacing the speakers is the best step.
Before using this guide, troubleshoot to identify whether replacing the speakers is necessary. Audio problems can come from issues unrelated to the speaker, such as the mute button being on. Troubleshooting steps can be found in this guide from Projector1.com.
Before proceeding with this guide, please ensure your projector is unplugged. Please note, "Step 2 requires that you take extra care when you lift the lid: move slowly and carefully to avoid ripping the electrical strips."
This guide demonstrates step-by-step instructions on how to remove the speakers in your InFocus LP540 Projector. No special skills are needed; it's as simple as unscrewing screws and removing the two speakers.
According to the InFocus LP540 manual located on Manuallibs.com, the speakers are 3-inch diameter and 8 Ohm. This product has been discontinued, but replacement speakers can be found on sites like Amazon.com.
