Common Causes of Hisense TV Black Screen

1. Power Supply Issues

Power interruptions or faulty adapters can cause the screen to remain black even when the TV seems on.

2. Faulty or Loose HDMI and AV Cables

Damaged or poorly connected cables are a frequent cause. HDMI handshake issues can prevent the picture from displaying.

3. Software or Firmware Glitches

Outdated or corrupted software can freeze the display or cause a black screen.

4. Hardware Failures

Issues with internal components like the T-Con board, mainboard, or backlight may result in black screens.

5. Wrong Input Source Selected

The TV might be set to an inactive HDMI port or source.

6. Overheating or Electrical Surges

Excess heat or power surges can damage components leading to black screen issues.

7. Remote Control Malfunction

Sometimes, the screen is black due to unintentional power-saving modes triggered by remote control errors.

Step 3: Confirm Input Source

Advanced Fixes: When the Problem Is Internal Hardware

Checking for Backlight Failure

If you can hear sound but the screen remains black, the backlight may be faulty. To test:

• Shine a flashlight close to the screen at an angle. If you can see faint images, the backlight is likely the problem.

T-Con Board Issues

The Timing Control (T-Con) board controls the image display. Symptoms of failure include flickering or black screen shortly after powering on.

Mainboard Failures

A defective mainboard can cause complete loss of picture. This typically requires professional repair.
