  • Hisense Smart TV won’t turn on

If your Hisense Smart TV won’t turn on, the first thing to do is to check if it has a power problem. There may be a problem with the power supply that needs to be fixed.

Try plugging it into a different AC outlet.


There are several ways to fix this issue. Here are a few:

  1. Disconnect the TV from the power source or wall plug.
  2. Please wait about 60 seconds.

If the above resolves the problem, you will need to factory reset your Hisense Smart TV, but it returns a day or a week later. Here is how:

Depending on the content you are watching, you may need to adjust your TV’s picture settings manually. To do this:

  2. A side menu will appear.
  3. To bring up the full menu options, press the right directional key.
  4. Choose a picture mode.

In Picture Mode, you must adjust various settings to determine the right brightness level. Generally, you can optimize your picture settings by making sure the following values are present:


  • Picture Mode – Theatre Night
  • Colour – 49
  • Backlight – 52
  • Colour Space – Auto
  • Contrast – 47
  • Brightness – 51
  • HDMI Dynamic Range – Auto (not adjustable)
  • Colour Temperature – Low
  • Gamma – 2
  • Sharpness – 0
  • Tint – 0
  • HDMI 2.0 format – Enhanced

Make sure all other settings are set to OFF or zero. Let the RGB colour sub controls default to their default settings. In addition, most of these devices come with preset brightness and colour settings.

You can modify the settings to make an image appear the way you want it to. When you switch between presets, your TV’s brightness can be adjusted depending on the content you are watching.

In the event that the above does not work, reset your TV to factory settings.

  2. Disconnect it from the power source.
  3. Please wait 30 seconds
  4. Connect the power cord and turn on the device.
