Fix Sharp Aquos Digital Audio Output Not Working

A series of steps to fix Sharp Aquos Digital Audio Output Not Working. What do you do when your Sharp Aquos Digital Audio suddenly stops working?

Don’t worry, simply follow the instructions mentioned below in the article and you will be able to solve the issue.

Know What Kind of Connector You Have

When you’re having issues with your audio on a TV, it helps to know which kind of connector you have. In addition to HDMI and digital audio output, some TVs also have more advanced versions such as HDBaseT and MHL.

These are often found on higher-end TVs, but some older models may still use them. You’ll need a different type of connection for each—HDMI or MHL for HDBaseT, or an optical audio cable for MHL.

1. Check if your Device Is ON

A lot of times, digital audio output devices will lose their settings and power. To fix this, turn off your device completely, then turn it back on after a few minutes.

If you’re having trouble with your speakers, try plugging them into another port to see if that fixes anything.

If all else fails, reset your system by unplugging it for a full 10 seconds. This will cause a system reboot that could potentially fix issues with your graphics driver or video output configurations.

If nothing changes, there might be an issue with your sound card or other components that can only be fixed by replacing them.

Your best bet is to consult a professional who can test out each component individually until they find what’s causing problems.

2. Unplug Other Devices

Make sure that no other devices are plugged into your TV’s digital audio output port. The device may not be working if you have multiple devices plugged in. Or one could use up a certain amount of power from your TV.

In order to fix the sharp aquous digital audio output not working try unplugging all but one device, and then restart your TV. If you do not hear sound after doing so, plug in another device and see if it works.

If it does work, then there is an issue with one of your other devices causing interference. Unplug them until you can find out which one is causing issues.

3. Try with Old Cables

If your audio jack isn’t working, try using different headphones and other cables to see if there is a problem with your jack. If you know that your cable works and it is only not working with certain devices, then it could be a fault on that device’s end.

In case you have an old phone or tablet that uses a 3.5mm jack (if you’re not sure, take a look at your device), try plugging it into your laptop as opposed to directly into another device like an amp or speaker system.

This will help isolate any issues in order to determine if they are specific to whatever piece of equipment you are connecting directly into.

4. Check All the Inputs

When digital audio output not working on your TV, check to make sure all cables are properly connected to your TV and device. (Each connection type has different ports, so you’ll need to consult your TV manual if you have any trouble figuring out how each one goes.)

If you have a coaxial cable or an optical cable, you might need to switch these between inputs depending on what devices you want to use with them.

It can be helpful to have a second set of hands around when switching these since they require some physical effort (like getting up and unplugging one end from a port).

You can also try unplugging everything from your TV for five minutes and then plugging it back in; that sometimes fixes connectivity issues between input ports.

5. Compatibility Issue

Many issues with digital audio can be traced back to simple compatibility problems. The most obvious is trying to send your digital audio signal through a device that’s not capable of handling it.

The TV you want to connect with the Sharp sound system might not be compatible with the speakers or the version may not be the same. You can check the website of the speakers that with which devices they are compatible.

Check the compatibility and then try again. Hopefully, you will be able to notice the problem. If it is a compatibility issue, then change the system.

6. The Software Version of the TV May be Old

1. Go to Settings, then select System.

2. Select About, then press right and select Firmware Version.

3. If your software version is old, you will need to update it.

This can be done by going to Sharp’s website for your TV model and downloading an update file. You can also check with a local TV repair shop for help updating your software if you don’t feel comfortable doing it yourself.

They may charge a fee for their services, but it should be cheaper than buying a new TV altogether.

7. Sound Card Problem

If your sound card is not working correctly, you may notice one or more of these symptoms: distorted audio, no audio at all, and popping and clicking sounds in your audio output.

The sound card of your TV might be out of order due to which you are facing the issue of Sharp Aquos Digital Audio not working.

If you notice that your sound card is not working fine, you should probably change the sound card or if possible, the TV itself.

8. Take the Unit to a Service Center

If your audio ports work with headphones, but not with external speakers, you may need to take your unit in for a service.

Check with your product’s warranty to see what is covered and whether or not there are any out-of-warranty fees associated with repairs. You can visit Sharp Support.

Also, check with your local electronics store as they often have repair facilities as well. Alternatively, you could try doing some of these simple fixes yourself before taking it into a shop or attempting any repairs yourself.
