Speaker, Amplifier & Audio-Out Fault Repairs

TV with picture but no sound is usually an internal-amplifier, speaker, or audio-output fault. Sometimes it is a settings issue — check audio output mode and mute state first. Where the fault is hardware, we repair on site or in workshop.

Common Causes

What Usually Causes This Problem

Most cases trace back to one of the following root causes. Our technicians diagnose with a signal meter and the right diagnostic tools on every callout.

Audio mode set to external speaker

TV is set to output audio via HDMI ARC or optical — but no soundbar is connected. Quick to reset.

Mute or zero volume

Always worth checking — remote handover can leave mute active.

Failed internal speaker

Internal TV speakers occasionally fail. We replace where economical or recommend a soundbar.

Audio amplifier IC failure

The internal amplifier chip can fail. We diagnose with workshop tools.

HDMI audio handshake fault

Sound works on some inputs but not others — usually HDMI ARC negotiation.

Soundbar configuration

If you have a connected soundbar, the issue may be in the soundbar settings or input mode.
