Will your Hisense TV not turn on? Or is the red light flashing while your screen is black? You'll find that there are a lot of reasons why a TV appears to be off when it's actually on, but there are also a few fixes for this issue. This wikiHow article lists some troubleshooting steps you can use when you find your Hisense TV is not turning on.

Things You Should Know

  • The easiest and most common fix that people use is simply power cycling their TV.
  • Although it doesn't seem directly related, changing your remote's batteries might make a difference in how your Hisense TV behaves.
  • If the red light is on or flashing but the TV screen is dark, use a flashlight to determine if the backlight is broken.

  1. You want to make sure that the TV doesn't have any backup or excess charge from being plugged in.
    • This is also called a soft reset. All you need to do is unplug the TV from power, leave it unplugged for about 60 seconds, press the Power button on your TV (not the remote) for about 30 seconds (without it plugged in), then connect it to power again.[1]
    • Try to turn your TV on after it's plugged in and see if your issue is resolved! If not, continue to the next steps.

Check the input source.

  1. For example, if your Xbox is connected to HDMI port 2 and you have the TV set to HDMI 1, it will appear off but the light will shine red. Here's what you can do to make sure you have the right input selected:[3]
    • Turn on your TV and see if the screen lights up before going dark, press Input or Source on your remote to change through the Inputs and see if any others are working (if you don't have your remote, you can press the Input button on the TV).
    • If switching through the sources on your TV doesn't work, try your Input devices (like your streaming box, DVD player, or console) with other TVs using the same cable to see if it works.
    • If it doesn't work, there's something likely wrong with your Input device or the cable.

Check the HDMI port and cable.

  1. Since HDMI is responsible for both sound and picture, a damaged port or cable could cause one to work and not the other. So maybe you hear audio but don't see pictures whenever you turn your TV on.[6]
    • To fix this, remove the HDMI cable and firmly plug it back in, then see if the issue is fixed.
    • If the previous troubleshooting step didn't work, remove the HDMI cable and plug it into a different HDMI port (if you have more than one).
    • Finally, use a different HDMI cable if you believe the cable is faulty.
    • Check other cables (RCA, coaxial) if you use those instead of HDMI.

Do a factory reset without the remote.

  1. A faulty software update or even little kids and pets can unintentionally mess up settings that help the TV function properly. A factory reset will not only return your TV's settings back to the original settings, but it will also erase any personal data that you put on it, like your Wi-Fi network information.
    • To reset without a remote, take a small, thin tool (like a straightened paperclip) and press the "Reset" button on the back of your TV for about 15 seconds.[7]
    • If you can't find a "Reset" button or hole anywhere on your TV, you can also press and hold the "Input" button and "Volume down" button down for about 30 seconds.

Make sure the TV's hardware is functioning.

  1. Hardware issues are a lot more difficult to fix and might require you to buy a new TV if you aren't very handy.
    • To test if this is the issue, make sure you're in a dark room (so you can see your TV's lights). Look through the back vent of your TV for any signs of lights. If your TV doesn't have a vent, you'll have to remove the back panel, but don't try that if you're not handy.
    • If you see lights through the back vents but the TV doesn't show images, your issue is most likely the TV's T-Con board or the main board.
