There’s nothing more frustrating than sitting down to watch your favourite show or the footy, only to discover that while your TV’s picture is perfectly clear, there’s no sound. Whether it’s a sudden glitch or a persistent problem, a silent screen can leave anyone feeling puzzled.

If you’re searching for a reliable tv repair service, understanding the common causes of TV audio issues is the first step toward restoring your viewing experience. In this guide, we’ll take you through the main reasons your TV might be showing a picture but no sound, practical troubleshooting steps you can try at home, and guidance on when professional help is needed.

Common Causes of TV Sound Issues

Even when your picture is flawless, a silent TV can occur for various reasons. Understanding the source of the problem can save time and stress.

Hardware Issues

Sometimes the problem lies within the TV itself. Faulty internal speakers, loose connections, or issues with the audio board can all cause a TV to display a picture without producing any sound. This can happen regardless of whether your device is an LED or LCD TV repair model. Signs of hardware problems include distorted or crackling sounds before the audio disappears entirely, or the TV not responding to volume controls.

Software or Settings Issues

Often, the culprit is much simpler than faulty hardware. Audio problems can arise due to muted settings, incorrect audio output options, or glitches following a firmware update. Smart TVs, in particular, can sometimes default to external audio devices, leaving the internal speakers silent. Double-check your settings before assuming a hardware fault.

External Devices and Connections

Audio issues aren’t always caused by the TV itself. Connected devices like soundbars, HDMI cables, or streaming devices can interfere with sound output. A faulty HDMI port or a disconnected AV cable might be the simple explanation for a silent screen.

Step-by-Step Troubleshooting

Before arranging professional service, there are several steps you can take to identify and potentially resolve the issue.

Checking Basic Settings

Start with the basics. Ensure your TV isn’t muted and the volume is turned up. Check the audio output mode in the settings menu, ensuring it’s set to internal speakers if no external sound system is being used.

Inspecting Physical Connections

Examine all connections. HDMI, RCA, AV, and optical cables should be properly seated and in good condition. A loose connection could easily be the cause of your audio problem.

Resetting the TV

Sometimes, a simple reset can fix software-related issues. Power cycle the TV by unplugging it for a few minutes and then turning it back on. For persistent problems, a soft reset or a factory reset may resolve glitches that are affecting audio output.

Testing External Devices

If your TV is connected to other devices, such as a soundbar, gaming console, or streaming box, disconnect them one by one to see if the audio returns. Sometimes, the TV mistakenly outputs audio to the wrong device, causing internal speakers to remain silent.

When Professional Help is Needed

While many audio issues can be resolved at home, there are times when professional attention is the safest option.

Recognising Hardware Failures

Internal faults such as burnt speakers, damaged audio ICs, or failing main boards are not easily fixed without expertise. If your TV has these symptoms, attempting DIY repairs could worsen the issue.

Choosing the Right Repair Approach

Complex problems should be repaired by professionals. Be it the repair of a Smart TV, LED TV, or LCD TV, qualified technicians are equipped with tools and expertise that will help them repair your TV safely and effectively. Finding a Reliable TV repair Adelaide can guarantee your TV is serviced and will not be damaged anymore.
