Understanding the Black Screen With Audio Issue in Sansui TVs

When your Sansui TV plays audio but the screen stays black, it typically means the device is powered on, but something is preventing the display from functioning. This is known as a “black screen with audio” or “no picture but sound” issue.

Common symptoms include:

1. TV turns on, but there is no picture
2. Faint images visible only when shining a flashlight
3. Display flickers once and then goes black
4. Menus do not appear
5. Sound works through TV speakers or external devices

Major Causes of Black Screen Problems in Sansui TVs

1. Backlight Failure

Backlight issues are the most common cause. LED strips may burn out or driver boards may fail. When this happens, the display has no illumination.

2. T-Con Board Malfunction

The T-Con (Timing Control Board) manages picture output. A faulty T-Con results in a blank or flickering screen.

3. Loose or Damaged Display Cables

Internal ribbon cables can loosen over time or due to shocks. This disrupts image transmission.

4. Power Supply Damage

The power board may fail to deliver voltage required for the display panel or backlights.

5. Software or Firmware Errors

A corrupted update can cause the screen to go black while audio continues.

6. Panel Damage

If the TV was hit or exposed to moisture, the display panel can fail completely.

How the Sansui TV Service Center Diagnoses the Issue

The Sansui TV Service Center follows a structured inspection process. This ensures the root cause is identified without guesswork.

Diagnostic Steps Include:

Checking TV voltage and power supply
Testing LED backlight response
Inspecting T-Con and main board
Running internal display self-tests
Verifying firmware functionality
Examining ribbon cable connections
Evaluating the display panel for physical damage

Technicians use tools such as multimeters, LED testers, firmware analyzers, and diagnostic kits to ensure accurate fault detection.

Repair Solutions Offered by Sansui TV Service Centers

Once the diagnosis is complete, the service team provides the appropriate solution:

Backlight Replacement

If LED strips are faulty, they replace them with genuine components.

2. T-Con Board Replacement or Repair

Repairing or replacing the T-Con restores picture functionality.

3. Motherboard Repairs

If the display processor is faulty, board-level repairs may be required.

4. Power Supply Replacement

A damaged PSU is replaced to restore voltage output.

5. Software Reinstallation / Firmware Upgrade

Software issues are fixed by updating or reinstalling firmware.

6. Panel Repair or Replacement

If the screen itself is damaged, the service center advises on repair or replacement options.
