A television that produces sound but displays no picture can be frustrating for VU TV owners. This issue usually points to internal problems like backlight failure, T-CON board malfunction, or power supply issues. To restore your TV to full functionality, the most reliable solution is to visit a VU TV Service Center.
Audio without a picture indicates that while your TV’s internal circuits are working to produce sound, the components responsible for the visual display are malfunctioning. Attempting DIY repairs can be risky and may further damage your TV or void the warranty. Professional service centers, including trusted providers like Dial Service Centre, have skilled technicians and original components to ensure accurate and lasting repairs.
Several factors may lead to a black screen while audio continues:
LED backlights illuminate the screen. If they fail, the display remains dark even though the TV is powered on.
The Timing Control (T-CON) board transmits the video signal to the display. A defective board can result in a blank screen.
Faulty power boards may fail to supply voltage to the display while audio circuits still function.
Cracks or internal panel damage can cause total picture loss.
Internal LVDS or HDMI cables that are loose or damaged can block the video signal from reaching the screen.
Sometimes a TV software glitch may cause a black screen while the audio works fine.
You can perform some basic checks to rule out simple issues:
Shine a flashlight close to the screen. If faint images appear, the backlight is likely faulty.
Ensure HDMI, AV, and power cables are securely connected and in good condition.
Switch inputs using your remote to make sure the TV isn’t set to the wrong source.
Turn off the TV, unplug it for 5–10 minutes, then power it back on to reset the system.
Connect a different device to rule out source problems.
If the issue persists, the problem is likely internal and requires professional attention.
