TV Has Picture But No Sound? Here’s How to Fix It

Your TV turns on, the picture looks fine — but there’s no sound.
This is a surprisingly common issue in Irish homes, and it doesn’t always mean your TV is broken.
In this guide, we’ll show you step-by-step how to fix it — or when to call a technician.

Step 1: Check the Volume and Mute Settings

Let’s start with the obvious — but important:

Make sure the volume isn’t muted
Try turning the volume up using both the remote and the TV’s physical buttons
Check your TV speakers setting (some TVs default to external speakers by mistake)

Step 2: Test With a Different Channel or App

Sometimes the sound problem comes from the source, not the TV itself.

Try this:

Switch to another channel
Play a YouTube video or use Netflix
Try a different HDMI input (if you’re using an external device)

Step 3: Check External Devices (If Using One)

Using a Sky Box, Chromecast, Fire Stick or soundbar?

Unplug and reconnect the HDMI or audio cables
Try another HDMI port
Restart the external device

Sometimes the HDMI handshake fails, which cuts audio even though the picture is fine.

Step 4: Inspect the Audio Settings

Go into your TV’s sound/audio settings and look for:

Speaker settings: Set to “TV Speakers”
Digital output format: Set to PCM for best compatibility
Sound delay or sync options: Reset them if needed

If you use a soundbar or home theatre system, try disconnecting it and testing the TV speakers directly.

Step 5: Perform a Soft Reset

Unplug your TV from the power outlet for about 1 minute, then plug it back in.
This resets temporary glitches in the sound system or software.

Step 6: Update the Firmware

Outdated software can cause bugs with sound.

Go to the Settings > Software Update
If your TV is not connected to Wi-Fi, check the manufacturer’s site and install updates via USB

When to Call a TV Repair Specialist

If none of the above works, you may be dealing with:

A faulty internal audio chip or mainboard
A damaged speaker inside the TV
Software corruption that can’t be fixed with a reset

A certified TV repair service in Ireland can diagnose this quickly and offer an affordable fix.

Final Thoughts
