Television is a key part of home entertainment, but it can be frustrating when your TV malfunctions. One common issue Hisense TV owners face is having sound without a picture. While you can still hear the audio, the black screen renders the TV unusable. If you encounter this problem, contacting a Hisense TV Service Center is the most reliable solution. Authorized service centers have the expertise to diagnose the problem accurately and restore your TV to full functionality.
In this blog, we’ll discuss the common causes behind a black screen with sound, troubleshooting tips, and the specialized repair services offered by Hisense TV centers in different cities.
Common Causes of No Picture but Sound
Understanding why your Hisense TV has no picture can help in deciding the next steps. Some of the most frequent causes include:
Backlight Failure: In LED and LCD TVs, the backlight illuminates the screen. If it fails, the screen stays black even though the audio continues to work.
T-Con Board Malfunction: The Timing Control (T-Con) board manages the video signal. Any fault here can lead to a black screen.
Power Supply Issues: If certain circuits receive power while others don’t, you may get sound but no display.
Loose or Damaged Cables: HDMI, AV, or internal connections that are loose or broken can cause the picture to disappear.
Software Glitches: Sometimes, firmware issues or corrupted system files affect the display while leaving audio functional.
Panel Damage: In rare cases, the TV’s panel itself may be faulty or damaged.
While minor issues like loose cables can sometimes be resolved at home, most of these problems require professional repair.

Troubleshooting Tips for Hisense TVs
Before contacting a service center, you can try a few basic troubleshooting steps:
Check All Connections: Ensure HDMI, AV, and power cables are securely connected. Replace any faulty cables.
Reset the TV: Unplug the TV for 10–15 minutes, then plug it back in. This can reset internal circuits.
Switch Inputs: Test different HDMI ports, channels, or connected devices to identify input-related issues.
Test Backlight: Shine a flashlight on the screen. Faint images indicate a backlight failure.
