Why Does The TV Turn Off Automatically?

The TV can turn itself off due to various reasons. However, when we involve an HDMI cable, the list of possible causes goes down significantly. Here are some of the possible causes for this problem:

HDMI CEC: The CEC feature allows different devices that are connected to your TV (via the HDMI cable) to be switched on or off automatically. So, for example, a soundbar or a gaming console connected via the HDMI cable is switched on; this feature will switch on the TV to the correct input. An easy solution would be to disable this function and see if that solves your problem.

Sleep Timer: Even though this has nothing to do with the HDMI connection, it is still a big cause for TV switching off. If you have this option on, then turn it off and see if that works.

Out of Date Firmware: If you haven’t updated your TV in a long time, it may be messing with its functionality. You should update your TV regularly to avoid running into such problems.

Output Resolution Mismatch: Sometimes, the output that your connected device is sending can be different from the one your TV can display. In such cases, the TV does not display anything. This is also a very probable cause of your problem. It can easily be curbed by changing the output resolution from the connected device.

Other Issue: Hardware issues may also be significant in such problems. If the HDMI port is broken, then it may not display anything on the screen. Such issues can only be solved by a Samsung expert at a service center.

Why Does Samsung TV Turn Off When Connected To HDMI?

A Samsung Smart TV also has the CEC feature explained above. It also has similar causes; thus, it turns off when any of these cases are triggered.

How To Stop A TV From Turning Off Automatically?

You can try to switch the CEC option off. However, if that does not work, you should try factory resetting the TV and updating its firmware.

1. Switch the CEC Option Off

Follow the steps below to learn about switching the CEC off.

  1. Look for your company’s CEC option in the TV’s menu. Each manufacturer has its own name for this function; For example, Samsung CEC is known as Aynet+, Sony’s is called Bravia Sync, LG calls its CEC SimpLink, and so on.
  2. Find your CEC option name from the TV’s manual or from the internet.
  3. Select it and disable it from the “menu” options.

2. Soft Reset Your TV

Simply turn off your TV, unplug it from the wall,  and leave it unplugged for at least thirty seconds before plugging it back in and turning it on. A soft reset will remove excess electricity in the TV’s circuit and return all the electrical components to their turned-off state.

3. Turn Off the Sleep Timer

The sleep timer turns off your TV automatically after a fixed period of use and can cause it to turn off when connected to HDMI too. Turn this feature off by:

  1. Select Settings and go to General
  2. Choose System Manager and then Time
  3. Scroll to Sleep Timer and turn it Off

4. Check your TV Remote

Low battery levels or a stuck button could be causing your remote to fire signals unnecessarily. Check your remote for any sticky or stuck buttons and replace the batteries with new ones.

Other TV remotes may also interfere with your  TV. Use them with your  TV and see if your TV reacts to it. In case it does, you might need to increase the distance between your TVs.

5. Check Your Power Connections

Inspect your power cable for any exposed wires or signs of tears. Make sure you are using a high-quality HDMI cable, and nothing is damaged or loose. Disconnecting and reconnecting the cables can solve the problem.

Try replacing them with new ones and connecting your TV directly to a wall outlet instead of a surge protector (in case you are using one). If your TV still turns off by itself, you can eliminate the possibility of a faulty power supply.

6. Adjust your TV’s Eco Solution

Samsung’s Eco Solution feature turns off your TV after some time of receiving no input. Turn this off by

  • Going to Settings
  • Select General and then Eco Solution
  • Choose Auto Power Off and select Off

You can also try turning this function on to see if it makes any difference.

7. Update Your TV’s Software

If this does not solve your issues, then you should try to update your TV’s software from the main menu. The process differs slightly depending on your TV’s manufacturer, but here is a general guideline:

  1. Go to Settings
  2. Select Support
  3. Select Software Update
  4. Select Update Now

8. Disconnect From the Internet

Devices such as your phone, smart home devices, and other TVs connected to the same internet network as your TV can communicate with it. These devices may turn on your TV by sending it commands and cause it to turn off by itself.

Try disconnecting your TV from the Internet for a few hours and see if it does the trick.

9. Factory Reset Your TV

Factory reset is your last option as it will refresh everything and allow any bugs in the system to be washed out. It can be done from the “Menu” options on your TV. Remember, you will lose all of your stored data by using this last resort option.

  1. Open Settings
  2. Select General
  3. Select Reset, enter your PIN (0000 is the default)
  4. Select Reset
  5. To complete the reset, select OK
  6. Your TV will restart automatically
