#1: Power Cycle Your Hisense TV
The first and easiest solution is to perform a power cycle on your Hisense TV.
Turning off your device, unplugging it from the power source, waiting for a few minutes, and plugging it back in clears glitches or bugs causing the red light problem.

- Plug the TV back into the power outlet.

Note: Ensure you unplug it from the power outlet and not just power it off from the remote control. Do not press any buttons on the TV during the power cycle.
#2: Look for Power Source Issues
Power issues are another cause of this error on the Hisense TV.
Check the power cord, the wall outlet, and the surge protector for damage or looseness to rule them out.
Here’s what you need to do:
- Check the power cord for secure connections and damage.
- If damaged, replace it.
- If you have another compatible power cord, use it and see if it fixes the problem.
- Test the wall outlet’s functionality with another device.
- If it doesn’t work, use a different outlet for the TV.
- Contact a qualified technician to fix a faulty wall outlet.
Note: If you have checked the power cord and wall outlet and your Hisense TV is still blinking, the problem is with the TV itself.
#3: Replace Your Remote’s Batteries
Another culprit to your “Why is the red light blinking on my Hisense Roku TV” problem is low or dead batteries on the remote control.
It prevents your remote from communicating with your TV, so replace the batteries with fresh ones to fix it.
- Locate the battery compartment on the back of your remote control.
- Use a coin or small screwdriver to open the battery compartment.
- Remove the old batteries.
- Insert the new batteries, matching the positive and negative terminals.
- Close the battery compartment.
Tip: Use new, alkaline batteries, not rechargeable ones, to ensure reliable performance.
#4: Check Your HDMI Ports and Cables
If the HDMI cable and port are faulty and poorly connected, you will have signal and input switching problems.
As a result, you will need help navigating between devices and sources in addition to the need for audio or video output.
To check your HDMI ports and cables, follow these steps:
- Turn off your TV and connected devices.
- Unplug the HDMI cables from both ends.
- Inspect the HDMI cables for signs of damage.

- Turn on your TV and connected devices.
- Choose the correct input source on your TV with the Input button on the remote.
Pro Tip: Periodically inspect your HDMI cables and ports for damage or loose connections to prevent potential signal and input problems with your devices.
#5: Disable the HDMI-CEC Option on Your TV
The HDMI-CEC feature allows two-way communication between your TV and connected devices.
It automatically switches the input source and turns on or off your devices using a single remote.
However, sometimes, it causes conflicts that cause a blinking light.
To fix this, turn off the HDMI-CEC option by following these steps:

- Select Settings.
- Choose Channels & Inputs.
- Click on Inputs.
- Choose the HDMI port of the device you want HDMI-CEC disabled.

#6: Set the Correct Input Source
If you’re still asking, “Why is my HisenseTV red light blinking?” at this point, the problem is with your input source.

To fix this, set the correct input source using these steps:
- Press the Input button on your TV remote control.
- Use the arrow buttons to select the input source you want to use.
- Press the Enter button to confirm.
Here’s a list of the common input sources on a Hisense TV:
- HDMI – the most common input source for connecting external devices
- AV – used for connecting older devices that use composite or component cables
- DTV – used for receiving over-the-air channels
- USB – used for connecting USB devices like flash drives and external hard drives
- VGA – used for connecting a computer to the TV
Note: Ensure your TV is set to the correct input source to receive a signal from your desired device; this simple step resolves many display and audio issues.
#7: Disconnect All External Devices
Your external devices also contribute to the Hisense TV blinking light issue.
Either your cable box, game console, or streaming device is the one causing interference or errors.
To fix this, disconnect all external devices from your TV.
To disconnect all external devices from your Hisense TV, follow these steps:
