Fixed: Hisense TV Won’t Turn On But The Blue Light Is On

Many Hisense TV users often run into issues where the blue light turns on, but there is no picture on the screen. This can be caused by several hardware or software issues.

What to do when your Hisense TV won’t turn on with the blue light on? Check all the connected cables by disconnecting and reconnecting them. Clean all the dust and dirt off them. Disconnect all connected devices like USB, streaming sticks, and cable boxes. Power cycle your TV by unplugging it from the power source and then plugging it back in after 1 minute.

We will be going through the most common problems, as well as how you can troubleshoot and solve them. Check out the list of the best streaming devices on Amazon now!

Why is Hisense TV blue light on But no Picture?

There can be a number of reasons why your TV might be acting out, here we will list the most common ones.

Incorrect Video Source

Your TV can display video from multiple inputs. These may include HDMI, cable, streaming apps, or locally stored content. You can change the video source to your desired content using the remote.

Sometimes the input you have selected might not have anything to display, leading to a blank screen even when the TV is turned on. This can occur due to faulty connections or selection of the wrong input.

Try changing the input using the steps in the next section.

Malfunctioning Backlight

Hisense LED TVs use a backlight to illuminate the screen and display the picture.

A backlight failure is the most common culprit for most TVs not turning on. Check the backlight using the steps in the next section.

Interrupted Power Supply

An inappropriate power supply can cause issues while turning on your TV. Voltage fluctuations, damaged wiring, damaged power socket, or a malfunctioning power surge protector can all be causes for your TV not being able to run smoothly.

Damaged Power Supply Board

The power supply board/unit is an important component of your TV. It consists of a bunch of capacitors and circuits that receive electricity from the main supply and then appropriately regulates and directs power to the different components of a TV.

Because the power supply unit is so complicated and because of the huge currents that flow through it, it is very susceptible to damage by voltage fluctuations or power issues.

Additionally, the capacitors in it quite often go bad, causing the whole power supply unit to fail.

What to Do when Hisense TV Doesn’t Turn on With the Blue Light?

Now you know the reasons, let’s get to the solutions right away.

Change Video Source

While your Hisense TV is on, use your emote to change the source of input on your TV. You can do this by pressing the input button on your remote.

In case the blank screen you were facing was caused by a faulty video input, this should solve your problem, and you should see at least a menu showing your different input options. This would be a sign that your TV is on but just does not have anything to display.

You can then go ahead and disconnect and reconnect the different devices attached to your TV to see where the problem lies.

Check Power Supply and Cord

Often a faulty wire, adapter, or power supply can cause your Hisense TV to not function smoothly as it does not get a reliable source of power to do so.

  1. Check the wiring for any fraying or exposed copper.
  2. Use another device on the power socket to ensure it is working perfectly.
  3. In case you have a power surge protector, use another device to check whether it is working.
  4. Try using an alternative power socket to see if the problem persists.

Check All Connected Devices

If you are using any kind of streaming stick like Fire Stick or Chromecast, make sure to disconnect them one by one and check if the blue screen disappears.

The same applies to any kind of USB stick connected to the back of your Hisense TV.

Power Cycle the TV

Sometimes some components in a Hisense TV (such as the capacitors) may hold a charge even when they aren’t supposed to. These charges can cause problems with your TV running as it should.

They can easily be taken care of by running a power cycle on your Hisense TV.

  1. Turn off your TV and unplug it from its power supply along with all other devices connected to it.
  2. Press and hold your TV’s physical power button for 30 seconds. (The power button should be on the bottom of the side of your TV, depending on your TV’s model. If not, press the power button on the remote instead.)
  3. Leave your TV as it is for 10 minutes.
  4. Plug your TV back in and turn it on.

A power cycle will reset all the hardware components of your TV to their original state and should resolve the issue if it was being caused by an inappropriately charged component.

Check the Backlight

  1. Turn on the Hisense TV using the remote or physical power button.
  2. Use a strong flashlight and point it at the screen of the TV at close range.
  3. Observe closely whether there are any visible images or words displayed. If you can make out letters or pictures, then your backlight is the culprit.
  4. In case you don’t see anything, press the power button on your remote or TV and check again.

Factory Reset the TV

This should be your last resort in case none of the previous steps work for you. This will reset all the settings and configurations of your device, bringing it back to its factory default state. Follow the steps ahead to do this.

The first step is to find the reset button on your Hisense TV. This can be quite small and can easily be missed, which is why it is best to look for it using the instruction manual that came with your TV.

Once you locate it, you will need to turn on your TV and press and hold the button for 15 seconds. You will need something thin like a pin or needle to do this because the reset button is usually located within a tiny hole to make it impossible to press by accident.

Check Capacitors

To check the capacitors on the circuit boards of your TV, you will need to remove the back panel of your TV. Do this only if you are sufficiently familiar with TV circuitry. Otherwise, simply move on to the next step.

It is also crucial to remember that opening the back panel can oftentimes void the warranty coverage of your device is still under the warranty period.

  1. Turn off and disconnect your TV from the power supply as well as any connected devices.
  2. If your TV is mounted on a wall, unmount it and lay it screen down on a flat surface such as a big table or floor. Ensure there is nothing on the surface that could possibly damage the TV screen.
  3. Remove all screws holding the TV’s back panel in place.
  4. Carefully remove the back panel and place it aside.
  5. Thoroughly inspect the boards in the TV and keep a lookout for any capacitors that look inappropriately inflated. Also, keep a lookout for signs of a short circuit, such as black burn marks, a burnt smell, and visibly fried components.
  6. Take note of everything you see.
