Understanding Your Hisense TV: Models & Features

Hisense manufactures a variety of TV models including ULED, Roku TV, Android TV, and Laser TV. Each has different hardware and software characteristics affecting how power and settings are managed. For example:

• Hisense Roku TVs rely heavily on Roku’s software ecosystem, which occasionally requires firmware updates.

Knowing your model helps tailor troubleshooting, so check your TV’s model number on the back panel or in the settings menu.

Primary Causes of Hisense TV Power-Off Issues

1. Power Supply Problems

The first thing to check is whether your TV receives stable and consistent power.

• Check Power Cables: Make sure the power cord is firmly plugged into the TV and wall outlet.

• Try a Different Outlet: Electrical issues like voltage fluctuation can cause shutdowns.
• Look for Visible Damage: Frayed or bent cables may need replacement.

• Disable or Adjust: Turn off sleep timer and energy-saving settings to test.

6. External Device Conflicts and HDMI-CEC

Connected devices can control your TV via HDMI-CEC.

• Unplug Devices: Disconnect all HDMI devices to check if one causes shutdowns.
