Televisions have become an integral part of modern homes, offering entertainment, information, and connectivity. Despite their advanced technology, TVs can sometimes encounter technical problems that disrupt their performance.

In this blog, we will explore the causes of no-picture-but-sound issues in Onida TVs, how service centers diagnose and repair them, and the specialized services available in major cities.

Common Causes of No-Picture-But-Sound Issues in Onida TVs

When your Onida TV produces sound but no picture, the issue is often related to the display system or internal processing. Common causes include:

1. Faulty Backlight

The backlight illuminates the screen, allowing images to be visible. If the backlight fails:

  • The screen may appear completely black

  • Audio may continue to work normally

Technicians replace damaged LED strips or repair the inverter board to restore the display.

2. T-CON Board Malfunction

The Timing Controller (T-CON) board manages the display timing and signals. Failure can result in:

  • Black screen

  • Flickering or distorted images

Service centers inspect the T-CON board and replace it when necessary to restore proper visuals.

3. Display Panel Damage

Physical damage or manufacturing defects in the display panel can prevent the TV from showing images. In such cases, panel replacement may be required.

4. Motherboard or Main Board Issues

The motherboard processes both audio and video signals. Signs of motherboard failure include:

  • No picture while audio works

  • TV freezing or unresponsive

  • Distorted display

Professional chip-level repair or motherboard replacement may be necessary.

5. Firmware or Software Glitches

Outdated firmware or corrupted software can prevent the display from functioning. Service centers address this by:

  • Performing firmware updates

  • Resetting the system

  • Optimizing software settings

6. Loose or Damaged Internal Cables

Loose or damaged internal cables can interrupt video signals while allowing audio to continue. Technicians ensure all connections are secure.
