Sound playing with a black screen is one of the most decisive symptom patterns in TV repair. Here's how likely causes are separated before money is spent.
With sound playing, shine a phone torch close against the dark screen at an angle. If you can accidentally see a faint moving image through the glass, the panel is rendering video and the LED backlight chain has failed — usually the LED bars themselves or the backlight driver circuit.
Faint image = backlight work (a common, well-defined repair). No faint image suggests main board or T-con issues, which produce different sub-symptoms: frozen logo, split-colour screens or hang-on-logo behaviour. An experienced technician sequences board tests rather than odds-guessing.
Backlights are far cheaper than panels. Many 'panel dead' verdicts are actually driver or bar faults — one reason a written diagnosis before part purchase protects your wallet.
