HDMI connectors allow TV users to access multiple TV channels and streaming services without the hassle of antennas and several cables. However, many users have reported that their Samsung TV turns off once the HDMI cable is plugged in.
Luckily, our professional TV techs have these surefire fixes ready for you to try and resolve the problem!
How to Get my Samsung TV Stay on With the HDMI Cable Plugged in
Fix #1: Disable Anynet+ or HDMI CEC
To get your Samsung TV to stay on while connected to HDMI, try disabling Anynet+ or switching off HDMI CEC.
You can use the Anynet+ feature to control HDMI-connected devices using the Consumer Electronics Control or CEC feature. This is mostly applicable to home theater components. However, they can partially control your Samsung TV, causing it to power off randomly.
Follow the steps below to disable Anynet+ on your Samsung TV:
- On the remote, navigate to “Settings,” then select “General.” After that, choose “External Device Manager.”
- Choose “Anynet+ (or HDMI-CEC)” and disable it.
- Finally, restart your Samsung television. Power it on for a while and observe if it still goes off after plugging in the HDMI cable.
Fix #2: Replace With a Certified, High-Quality HDMI Cable
One common fix is replacing your old HDMI cable with a certified, high-quality cable. Maybe your HDMI cable is already broken, so your TV powers off every time the cable is plugged in.
Examine your power cable for any exposed wires or signs of tears. Ensure you’re using a high-quality HDMI cable and that nothing is damaged or loose. Also, you can try disconnecting and reconnecting the cables to resolve the issue.
After replacing the cable, you can also connect your Samsung TV to the wall outlet directly instead of a surge protector (if you’re using one).
Fix #3: Disable the Sleep Timer
The sleep timer automatically turns off your TV after a set period of use and can also cause it to turn off when connected to HDMI.
To resolve the issue, you can disable the sleep timer by accessing your settings:
- Go to “Settings” and select “General.”
- Choose “System Manager” then “Time.”
- Scroll down and search for the “Sleep Timer” option and disable it.
Fix #4: Check for TV Software Updates
Software updates are crucial for your Samsung smart TV to work seamlessly. These updates can patch up glitches, including this black screen issue. To properly update your Samsung TV’s software, go to these settings:
- With your remote, access “Settings” and select “Support.”
- Choose “Software Update” then “Update Software.”
- Wait for the latest software updates to finish downloading and installing on your Samsung smart TV.
- Lastly, restart your TV. Once it’s turned on, observe if the TV still turns off.
When to Consult With a Technician
If, up to this point, none has worked for you, that’s when you need to consult an appliance technician as soon as possible. Technicians can properly diagnose the issue and have a sure way to fix it.
In fact, most issues requiring resolution on Samsung products are easy and can be fixed in just a couple of minutes as long as there are proper tools and expertise.
Conclusion
If you follow these above suggested solutions, you should be able to determine the underlying causes of why your Samsung TV turns off when the HDMI cable is plugged in. If you’re still encountering the problem after following the steps, there might be a hardware issue that you cannot resolve on your own.
If you require additional assistance, we recommend contacting a technician in your area or reiterating your concern directly at Samsung customer service.
