Why does my JVC Projector have No Sound?


JVC prides itself in making exemplary audio-visual equipment. Their projectors have a characteristic quality that influences many to rely on them. However, due to various reasons, you might not be getting audio from your JVC projector whenever you try to watch something. Keep reading as we look into the possible causes and solutions to get you back to enjoying your favorite shows.

You are not getting any sound from your JVC projector because it lacks inbuilt speakers. However, if you are using an external audio device, the main reason could be your connection setup. To fix this, connect your audio device directly to the projector’s video source and not to the projector. Alternatively, you can connect an external audio output to your projector depending on the JVC projector and speaker ports.

How Do I Get my JVC Projector to Play Sound?

Essentially projectors are not meant to play audio. Their primary function is to showcase images at a wider scale and with better quality. 

Additionally, standard projector sizes cannot accommodate quality speakers for outputting audio that can match the projector’s video quality. 

Most JVC projectors that have inbuilt speakers are no longer in production. Hopefully, JVC will manufacture more projectors with speakers rather than depending on external speakers for audio.

Therefore, to get your JVC projector to play audio, you have to connect it directly to an external audio output. 

Indeed, the setup is possible; however, it is not advisable because it will probably negatively affect the audio quality.

So, if you decide to go ahead and connect external audio, you can use active or passive speakers.

Active Speakers

Active speakers have inbuilt amplifiers and can connect directly to compatible devices. An example is the Edifier S3000Pro , and active speakers are also known as powered speakers or self-powered speakers.

Active speakers are more straightforward to connect than passive speakers since they require fewer connection paths. They also connect faster, especially if their ports are compatible with the projectors.

Passive Speakers

Passive speakers are those that require an amplifier to broadcast audible sound. They can connect via long wires, providing more flexibility when installing. The Dayton Audio B652-AIR  is an excellent example of a passive speaker.

Therefore, to get audio out of your JVC projector, you can use any of the following connections:

Using HDMI Connection

HDMI technology is a game-changer in the world of wired connections. The cables are capable of carrying compressed video and audio digital signals.

Therefore, if your audio output device has an HDMI port, connect it to the extra HDMI port on the JVC projector.

However, a significant downside of this setup is the distance between the two devices. Without significantly deteriorating quality, signals can only travel over limited distances through an HDMI cable.

Using RCA connectors

Older JVC projector models like the DLA-HD350/DLA-RS10 come with RCA ports for connecting stereo speakers. Each RCA cable goes to the speaker, and you get audio.

This connection is easy to establish because you connect the cables and then power on the devices. 

Unfortunately, newer JVC models do not come with RCA ports; therefore, you might need an HDMI to RCA converter  to play audio. 

Some converters also have a 3.55mm output port to connect to an external speaker, therefore, expanding your options even further.

3.5mm Jack Output

Another alternative is to use the 3.5mm output port on your projector. Before even considering this option, check on the 3.5mm ports and confirm the label says output.

It is essential to check the label because some projectors have 3.5mm ports that only allow input signals and not outgoing signals.

You will need a 3.5mm male-to-male cable  to facilitate this connection.

Additionally, you can use an audio extractor  to extract audio signals from HDMI and convert them to analog. 

Bluetooth

Bluetooth is not a standard feature on JVC projectors, therefore, rendering this sort of connection almost impossible.

But with a bit of tinkering and extra gadgets, you can make this a possibility. You will require a Bluetooth transmitter to connect a JVC model to an external Bluetooth-enabled device.

For instance, you can use the Avantree Oasis Plus  transmitter. 

Start by linking it to your projector and then enable Bluetooth scanning on the transmitter and Bluetooth speaker.

Once they connect, you can enjoy your video with better audio.

It gets complicated when connecting a JVC projector and speaker when both do not have the Bluetooth feature. 

You can achieve the setup by using a Bluetooth transmitter on both devices, but you might encounter various connection issues. Among them are lagging, constant disconnection, and poor audio than expected.

Why Does My JVC Projector have no Sound?

If you have tried any of the connections above and there is still no sound from the projector, a few things could be wrong. They include:

  • The connected devices could be incompatible. Recent JVC projectors use digital signals while most speakers are compatible with both signals.
  • HDMI connectivity is highly sensitive to any interference. Therefore, if any mishaps happen during signal transmission, devices might not work as expected. 
  • Outdated firmware on the projector can also result in connection issues. Older JVC models might find it hard to compare to recent technology.
  • The quality of your cables can also affect audio output from the JVC projector, especially if they are old or broken. Loose or damaged connections will also affect audio output on speakers.
  • The settings on the connected devices can also hinder audio transmission. 
  • You could be using a cable to convert signals from digital to analog. Digital-analog conversion requires a converter since lines cannot convert signals independently.
  • If you are using wireless connections, it is possible for signal interference from other wireless devices to occur. 

How Do I Fix this issue?

Here are some solutions you can try before considering professional help.

  • The first step is to ensure the speaker and JVC projector use compatible signals and the setup is correctly done. Your best option is to consult user manuals of the JVC projector and speaker, then carefully re-establish the connections.
  • Ensure you have the correct cables and each cable is firmly connected at the correct port. Also, be keen to note the labels on the outputs and inputs of both devices to avoid mismatching connections.
  • Consider using an AV receiver to conduct real-time signal conversion while also extracting audio signals from AV signals.
  • Check on whether you have an active or passive speaker. If you have a passive speaker, you will require an amplifier or AV receiver to get sound from the projector.
  • Confirm that your JVC projector and speaker are on the same audio channel. Also, ensure the volume is turned up on the projector and speaker if they allow volume tuning.
  • Re-establish the connections and restart the devices to have a fresh connection to solve temporary bugs, especially HDMI ones.
  • Shift between ports to rule out malfunctioning ports. If your projector has limited ports, you can use an  HDMI splitter  to increase the number.
  • Consider connecting the speaker to the video source instead of the projector. 
  • Get a better projector with modern and extensive capabilities. JVC projectors like the JVC DLA-NX9  have better firmware, thus fewer incompatibilities with other devices.
  • Prevent signal interference by shutting off devices that communicate via radio frequencies. They include baby monitors, microwaves, and Wi-Fi.
