Why Won’t Your Hisense TV Turn On?

Here are the possible reasons your Hisense TV won’t turn on:

Power Interruptions

If your TV isn’t getting a specific amount of power, it might fail to turn on. So, suppose the power supply adapter, power strip, power outlet, or any other part of the power supply unit is faulty; you’ll most likely experience this problem.

Hardware Malfunction

Faulty hardware can affect your TV’s normal current flow. The damaged hardware could also interfere with the relaying of electrical signals. The following hardware issues could cause your TV not to turn on:

  • The power board could be damaged. To confirm this, check if the red power light on your TV flashes when you press the power button.
  • The mainboard might be faulty. This is even more true if the power light stays red and doesn’t blink when you press the power button. 
  • The main fuse could be blown, probably because you unplugged the TV while it was on.
  • The capacitors on the circuit board might be defective. The signs of damaged capacitors on your TV include a flickering screen, dim screen, and screen image that disappears after some seconds.

Hisense TV Won’t Turn On, but the Red Light is On

If your Hisense TV won’t turn on, but the red light is on, the fault could lie with your remote control. If you’ve confirmed that your TV is receiving an adequate power supply and isn’t damaged internally, try checking whether the remote is faulty, its batteries are worn out, or something is blocking its signal.

How to Fix a Hisense TV That Won’t Turn On

There are several solutions for a Hisense TV that won’t turn on. Here are some of them:

Perform a Soft Reset

Some configuration settings might prevent your TV from turning on. If the settings are the culprit, you might notice the power light blinking severally, but the TV isn’t turning on. You’ll have to reset your TV to get rid of these settings. Here’s how to do it:

  1. First, unplug the TV from the wall outlet.
  1. Wait for around 60 seconds.
  1. Then, plug it back in and try switching it on.

Alternatively, you can reset the TV using these steps:

  1. First, unplug the power cord from your TV and all other connected devices.
  1. Next, find your TV’s Power button at the bottom or back, depending on your model.
  1. Press and hold the Power button for approximately 30 seconds to drain any residual power in the TV.
  1. After about 20 minutes, plug the TV back into the power source.
  1. Finally, switch it on using the TV switch and not the remote.

Check the Wall Outlet

Your Hisense TV might be OK, but the wall outlet could be the issue, hindering the free flow of current into your TV. As a result, your TV won’t get enough power supply and won’t turn on.

At times it might power on and then switch off suddenly. It could do this a lot due to a loose cable connection on the outlet. To find out if the wall outlet is the source of this issue:

  • Check if other devices on the outlet work fine, especially those that require a higher power supply.
  • Unplug your TV from the wall and try using a different power outlet.
  • Remove the power surge protector if you use one and plug the TV directly into the wall.

Troubleshoot the Power Input Slot

You could also check if your TV’s power input slot is damaged. Keep your eyes locked on the front panel where the red light usually is as you carry out these steps:

  1. Plug the power cable into a wall outlet you’ve confirmed is working well.
  1. Next, firmly plug the power cable’s other side into your TV.
  1. Start twisting the cord around.
  1. Try plugging it deeper into the TV’s power slot by applying a little pressure.
  1. Plug it in and out repeatedly.
  1. While the cable is inside the input slot, try twisting it around while applying mild pressure.

Troubleshoot Your Remote Control

Get rid of any object blocking the transmission of signals between the remote and your TV receiver. Moreover, temporarily remove any electronic devices away from your TV to avoid external interference. 

Once you’ve removed the signal distractions, press the Power button. If the TV doesn’t turn on, try pressing and holding the Volume Up and Channel Down buttons for around 15 seconds and check whether it works.

If the problem persists, you’ll have to troubleshoot your remote. Here’s how to do it:

  1. Discharge the remote by removing its batteries and pressing each button at least twice, then putting the batteries back in afterward.
  1. Remove the batteries and replace them with a fresh pair.
  1. Get a new Hisense TV remote.

Examine Your Power Cable and Power Adapter

A faulty power cable might supply insufficient or no power to your TV. The red power light may turn on or fail to do so, depending on the amount of current it receives. To check whether your power cable is damaged:

  • Inspect the cable for strange bends, cuts, and signs of material aging.
  • Borrow a friend’s power cable and test it on your TV to see if it works.
  • Observe if the red power light turns on when you plug the cable into the power source.

It would also be best to extend your inspection to the power adapter. The power adapter is another delicate part of your TV’s power delivery system. You could replace your adapter and check if the new one resolves the issue.

And be sure to use a surge protector like this model from Anker (on Amazon) that can protect your TV and other equipment from power surges.

Unplug All Unused Devices

Sometimes the TV and remote may not be the problem. For example, your Hisense TV could fail to turn on because of the devices you’ve plugged into it, such as streaming sticks. Remove any devices from the back of your TV and try switching it on.

If you use an HDMI cable extension, try replacing it or connecting your devices directly to the TV. You could also test other HDMI ports.

Disconnect All Network Devices

Your Hisense TV’s red power light might flash a couple of times, but the TV isn’t turning on. This could be due to a poor connection with your modem or router.

You could try resetting your modem and if the TV still doesn’t turn on, unplug your network device to see if it restores normalcy. If this solution doesn’t work, the fault might be with your TV firmware or hardware like the motherboard.

Check the Backlight

The most common problem for Hisense TVs is the LED backlight collapse. LED TVs use the backlight to illuminate the images displayed on the screen so we can see them. If you use a Hisense LED TV, check if the backlight is working. Here’s how to do it:

  1. Hold a bright flashlight 2 inches away from the screen with your TV on.
  1. Check if there are any visible images and words.
  1. If you spot an image where the flashlight ray hits the screen, the backlight could be defective.

LED backlight fails from a short in the mainboard or powerboard circuitry. Of course, you could take your TV to the repair shop, but in most cases, there’s no point in trying to repair damaged backlights unless your TV is new and expensive.

Remove the Back Cover and Examine Your TV

If you have any tech skills under your sleeve, you could open your TV’s back cover and use a voltmeter to check whether an electric current is flowing inside it. Ensure you ground yourself before removing your TV from the power source and opening the back cover.

Once you remove the back cover, do the following:

  1. Inspect your main and power boards for short circuits.
  1. Use your voltmeter to check if the power board supplies power to the mainboard. 
  1. Confirm whether the LED connectors have any voltage.

If there’s current flowing in the LEDs, then the LED arrays might have a problem, and you’ll need expert technical help to fix this issue.

Hard Reset Your TV

A factory reset might be the only option if you’ve tried all the above solutions, but the problem persists. Use it as a last resort as it removes all your installed applications and default settings. To hard reset your Hisense TV, follow these steps:

  1. Find the small hole labeled RESET on your TV. Depending on the model, you’ll find the hole at the bottom or back of your TV.
  1. Bend a paperclip and insert it into the hole.
  1. Press the clip inside the hole for about 15 seconds.
  1. Hold the clip inside the hole until your TV restarts.

Contact Hisense Customer Support

You could try contacting Hisense customer support if all the solutions have failed. The customer care representative might be able to take you through the entire troubleshooting process in a better way. When contacting the support team, ensure you mention:

  • Your Hisense TV’s model number.

The customer care representative can quickly check your warranty information using these details. If the warranty period hasn’t expired, you might get a free repair or even a replacement for your TV or remote.
