How to fix Hisense TV blinking red light



Restart the TV

If it’s a minor issue, then a soft reset or power cycling should solve your problem. Here’s how you can perform a power cycle – 

  • Make sure that the TV is turned off
  • Unplug the power adapter
  • Wait for up to a minute

  • Change the power adapter
  • Check the cable for any damage 



Try removing the surge protector and power strip

If it’s a power supply issue, then you can try changing the surge protector and/or the power strip if you are using these. Sometimes, if the surge protector or the power strip is not working correctly, it might prevent the uninterrupted flow of power to the TV, causing the red lights to blink.



Update the TV’s firmware

Sometimes, if your TV’s software is not up to date, then it might cause hindrances in regular functioning. While the exact process might be different for your model, the general process is the same.

  • Head over to the ‘Settings’ menu
  • Go to ‘Device Preferences’ or similar options
  • Find an ‘About’ section and locate the System Update option
  • The TV will look for available updates to install
  • Once the updates are installed, see if the red blinking lights are gone

  • Check the HDMI cable for frays and cuts
  • Check if the port is working properly
  • See if the HDMI cable is plugged in properly



Factory reset the TV

If there are any minor problems that are making the TV’s red light flash, then they can be resolved by a factory reset. Now, factory resetting your TV can erase the data from your TV, so it should be the last resort. 

Here’s a general rundown of the resetting process –

  • Then, look for the ‘Factory Data Reset’ or ‘Reset’ option
  • You might be prompted to enter a 4-digit code
