Remote in hand, you're ready to binge the latest season of your favorite show. But your Hisense® TV has a blinking red light and isn't responding when you press buttons. Is it time for a new smart TV, or is there a simple fix?

Asurion Experts provide tech tips you can trust. Whether you need to set up Roku or want to know when the best time to buy a new TV is, we've got the answers you're looking for. Here's what to do when your Hisense TV red light is blinking.

Understand what a blinking red light means

When a Hisense TV is in standby mode and ready to be turned on, its red LED light blinks once or remains solid. However, if the LED light blinks more frequently, it may indicate one of these issues:

• Two blinks: The device may have a connectivity or power supply problem.
• Three blinks: There may be a compatibility issue with a connected device or a problem with the internal circuit board.
• Four blinks: The backlight inverter wiring may not be functioning properly.
• Five blinks: The TV's motherboard may have failed.
• Six blinks: There could be an issue with the power supply or cooling system.
• Seven blinks: The device may have an internal circuit error that affects the LED backlight or capacitors.
• Eight blinks: The TV may be experiencing a hardware failure or cable connection issue.
• Ten blinks: There may be a problem with the TV's power supply or LED driver.

The blink pattern can help you narrow down the cause of a Hisense Roku TV™ blinking red light. This is important for troubleshooting the issue and fixing it.

Check and reset your power connection

Disruptions to your TV's power supply can cause a Hisense TV to display a blinking red light. Check your power cord to verify the TV is plugged in and has a proper connection.

• Confirm that all wires connected to the TV are in good condition. Frayed, bent, or exposed wires require replacement.
• Verify that the power cord is plugged into a working outlet. If you're using a surge protector, it may be faulty. Try plugging the TV directly into a wall outlet.
• Plug the TV into a different wall outlet if you continue to experience power issues.

Try a power cycle

Power cycling may eliminate any internal bugs that interfere with device performance:

1. Turn off your TV and unplug it from its power source.
2. Press and hold the Power button on the TV for 30 seconds.
3. Plug the TV back into its power source and try turning it on again.

Unplug external devices

Incompatible or damaged devices you plug into the TV may conflict with your device, causing the Hisense LED indicator to blink. Try:

• Unplugging gaming systems, speakers, and other external devices.
• Remove one item at a time to determine which is triggering the blinking red light.
• Switch HDMI ports to rule out a damaged connector.

Troubleshoot hardware or firmware issues

If your Hisense TV continues to display a blinking light after troubleshooting power supply and connectivity issues, it may have an internal fault.

Update the firmware

1. Unplug all external devices connected to the TV.
2. Turn on the TV and verify that it has an internet connection.
3. Press the Settings button on your remote.
4. Select Settings > System > About > System update.
5. Wait for the TV to download and install any available firmware updates.

If you're unable to turn on your TV or access the screen, the issue may be hardware-related.

When to seek professional help

A Hisense TV with an LED that blinks five times could indicate a motherboard issue, which may require a replacement TV. Other blinking patterns that could indicate internal component failures include four, seven, and eight blinks.

If the LED continues to blink after troubleshooting the power supply and firmware, consider getting help from an experienced support team. They can examine your TV for potential hardware failures and repair it if necessary.
