What you'll notice
Audio starts normally then fades to silence, or cuts in and out unpredictably.
Why it happens
A loose internal connector, a failing amplifier component under thermal stress, or a firmware audio-processing fault.
How we fix it
We reseat and test connections under sustained use to catch intermittent faults, then repair the confirmed cause.
Still not working?
If the checks above haven't restored your speaker & audio board, this usually needs a technician. Our TV No Sound Repair service covers exactly this fault.
