Can you repair a TV with sound but no picture?

Yes! When an LED TV has sound but no picture, in over 90% of cases the LED backlight strips inside the screen have failed. We replace the full set of strips at your home with brand-new OEM parts and a 90-day warranty.

How to tell if my TV backlight is broken using a torch?

Turn your TV on with sound playing, shine a smartphone torch closely onto the dark screen at an angle. If you can see faint images or menu text moving underneath the dark glass, your backlight array has burnt out and needs replacement.

Symptoms & Repair Process

Why Do LED Backlights Fail and How We Fix Them

LED backlights are connected in series. When even a single LED bead burns out or shorts, the backlight inverter circuit shuts down to prevent fire, leaving the screen dark while the motherboard continues to output audio.

1. Professional Flashlight Diagnosis

Our engineer inspects the TV using LED backlight voltage testers and angled light to verify that the LCD/LED matrix and T-Con board are intact before proceeding.

2. Complete Strip Set Replacement

We never replace individual diodes (which often fail again shortly). We replace the entire factory set with matching voltage, aluminum-heatsink strips for longevity.

3. Voltage Calibration & 90-Day Guarantee

We tune the power board's LED driver current to prevent future overheating, re-assemble the diffuser sheets dust-free, and issue an official 90-day warranty card.
