Sound repairs
Before anyone opens the television, half of all ‘no sound’ calls turn out to be an output setting, a soundbar handshake or an HDMI-ARC problem. We check the free fixes first.
We say this because it saves people money, and because we would rather tell you for free than charge you to discover it. A large share of the ‘my TV has no sound’ calls we take are resolved without opening the television at all.
The usual causes: audio output is set to an external device that is switched off or unplugged. HDMI-ARC has lost its handshake with a soundbar. A firmware update has quietly reset the audio format to something the connected equipment cannot decode. Or the television is outputting Dolby Digital to a device that only understands PCM, and the result is silence.
When it genuinely is a hardware fault, it is usually the amplifier section on the mainboard or the speakers themselves — and both of those are repairable. What we will not do is charge you for a board repair when the actual problem was a settings menu.
The detail
The symptom tells us where to look.
If the mute is off and the volume is up, this points at the audio output configuration, the amplifier circuit on the mainboard, or a failed speaker pair. We check them in that order, cheapest first.
The television is producing audio correctly and simply is not routing it to its own speakers. This is very often a settings fix, and it costs you nothing but the callout.
Usually a failing speaker, or an amplifier circuit that is beginning to break down. Distortion that gets worse as the volume rises points strongly at the amplifier.
Intermittent audio is frequently a dry solder joint on the amplifier section, or a loose speaker connector. Both are repairable, and both worsen if ignored.
Lip-sync drift is usually a processing or settings issue rather than a hardware failure, particularly when a soundbar or AV receiver is in the chain. Most sets have an audio delay setting that corrects it.
That points at the input rather than the audio system — an HDMI handshake problem, or a specific port that has failed. Which is a different repair entirely.

FAQ
The things people actually ask us on the phone, answered straight.
WhatsApp us the make, the screen size and a short video of what the TV is doing. We can usually narrow the fault down before a technician is even dispatched.
WhatsApp 063 866 0971Check that it is not muted and the volume is up — do not be embarrassed, it happens. Then check the audio output setting: if it is pointing at an external speaker, soundbar or Bluetooth device that is off or disconnected, the television will be silent. That single setting accounts for a remarkable number of the calls we take.
Usually not. That is the television doing exactly what it has been told to do — sending audio out rather than to its internal speakers. It is a settings change, and often we can talk you through it on the phone at no charge.
Most often a failing speaker driver or a deteriorating amplifier circuit on the mainboard. If the distortion worsens as you turn the volume up, the amplifier is the more likely candidate. Both are repairable.
It depends. A blown speaker generally needs replacing, and replacement speakers are usually inexpensive. An amplifier fault on the mainboard is more often repaired at component level than replaced.
Lip-sync drift, and it is usually a settings issue rather than a fault — particularly if a soundbar or receiver is involved. Most televisions have an audio delay adjustment that corrects it. We can walk you through it.
An honest question and it deserves an honest answer. If the amplifier repair is expensive and you were considering better audio anyway, a soundbar may be the smarter spend — and we will say so. If the fault is a speaker or a dry joint, repairing it is usually cheap and there is no reason not to.
