There is nothing more frustrating than a SAMSUNG TV Not Recognizing HDMI Input, but it is a very common problem with Samsung TVs of any age.
You might feel like giving up after seeing an HDMI no signal message on your Samsung TV.
By following these simple steps, you can actually fix this very easily.
If your Samsung TV HDMI doesn’t show any signal, it is almost certainly a software problem, so let’s get to work on fixing it.
Samsung TV Not Recognizing HDMI Input
You can fix HDMI port problems on Samsung TVs by power cycling them. Hold the power button for 15 seconds while unplugging your TV and waiting 30 minutes. The Samsung HDMI cable tester can also be used to test your HDMI cables.
Please refer to the steps below for more information on how to fix your Samsung HDMI ports.
Samsung HDMI no signal problems are usually solved by following these steps.
1. Cold Boot Your TV
Your Samsung TV’s HDMI ports can be faulty because something got stuck in your TV’s flash memory, according to modern electronics.
If there are any issues with non-permanent memory on your TV, power cycling or cold booting it will clean it up and reset your main board without affecting your personal settings.
You won’t lose any saved settings by doing this. It’s quick and painless.
- Switch on your TV by plugging it in.
- Disconnect the wall socket by pulling out the plug.
- Take a full 10 seconds to wait.
- Try turning on your TV after you’ve plugged it back in. Your success should be indicated by a red light.

When this does not work, you may need to power cycle the Samsung TV.
- Unplug your TV and switch it off.
- For at least 15 seconds, hold down the TV’s physical power button.
- The TV’s capacitors (which can store charge for several minutes) should be allowed to drain any residual power after 30 minutes.
- Reconnect your TV and try turning it on again.
You might be surprised how long the electronics inside your TV can hold a charge, so it’s important to wait for the full 30 minutes before plugging in your TV again.
Soft resets are usually sufficient to fix most issues, even though they seem like a very basic step.
Now that most people’s TVs are back up and running, they should be able to use them again. We’ll try some more basic fixes before moving on to hardware fixes if this is not you.
2. Change the HDMI Cable Socket
The TV may not detect the device because the cable is poorly seated.
There are two options here:
- The HDMI cable is broken and faulty
- Broken HDMI pins on damaged HDMI port
- Connector and cable do not fully engage in a good HDMI connection
You might have a bent pin in your Samsung TV’s connector or cable if it keeps losing HDMI signal. If this happens, you should replace the cable.
Cables and HDMIs should be checked as follows:
- Turn off the TV.
- Your TV’s back should be free of HDMI and other physical cables.
- You can use compressed air to clean the contacts in the TV connector as well as the contacts on the cable. You can blow on them gently if you don’t have compressed air.
- Make sure the TV cables are firmly inserted into their slots.
- Restart the TV.
Try using another HDMI input if that doesn’t fix the problem. HDMI ports are commonly found on three or four TVs.
That would be the best to try, as it should be connected to the TV’s main board differently than the one that is on the other side of the TV.
You can choose this HDMI input by using the Input or Source button on your TV remote, or the Input or Menu button on your TV. Once you have plugged your HDMI cable into the new port, note the number beside it and choose it on your TV.

3. Check Your TV / Device HDMI Specifications
The issue could be caused by different HDMI specifications if this is your first time connecting a new device.
A new cable design is used for 4K 120Hz viewing in Samsung TVs, which support HDMI 2.1, which is backwards compatible with older HDMI specifications.
In addition to the HDMI specifications on your TV, make sure you check the cable connecting the device and the device you are plugging in.
It is possible that an HDMI 2.1 device sends a signal the TV can’t interpret when you plug it into an older HDMI port.
Your device’s settings can be adjusted to fix this.
4. Update Your TV’s Firmware
There have been reports of HDMI port problems on Samsung TVs caused by software and firmware issues.
No matter how new your TV may be, you should ensure the firmware is up-to-date.
There is the option to update the firmware automatically on Samsung TVs, but this should not be assumed to be enabled.
Make sure your Samsung TV is set to auto-update firmware and software:
- Go to Settings by pressing the Menu or Home button on your remote.
- Please click on Support.
- After that, update the software.
- You’ll be prompted to agree to any terms and conditions, then you’ll have the option to turn on the Auto Update feature.
The firmware must be updated via USB on older Samsung TVs. This can be done by:
- Go to Settings by pressing the Menu or Home button on your remote.
- Visit the Support page.
- Get in touch with Samsung or contact the TV’s manufacturer.
- The current Software Version and Model Code should be noted.
- Enter your model number on Samsung’s Support site.
- Find the latest firmware version in Manuals & Downloads.
- The Firmware Update User Manual will give you instructions on how to install your update if this Firmware Version is newer than the version you noted on your TV.
5. Run an HDMI Self Test
The HDMI ports on Samsung TVs can be self-tested so you can troubleshoot and fix them yourself.
In order to access the HDMI self-test, follow these steps:
- On your remote control, press Home.
- Click on Settings.
- Next, support.
- You should choose Device Care.
- Including self-diagnosis.
- Try each port in HDMI Troubleshooting.
6. Samsung TV Not Recognizing HDMI ARC
Make sure your HDMI cable meets HDMI 1.4 specifications if you are using ARC or eARC.
Your Samsung TV’s ARC HDMI port needs to be used as well – ARC or eARC will be labelled. You should carefully check your TV’s HDMI port to ensure that it supports ARC.
Your TV must also be configured to support Anynet+ (HDMI-CEC) in order to support eARC.
To enable Anynet+:
- Using your remote, press Home.
- Click on Settings.
- Next, the general.
- In addition, there is an External Device Manager.
- Click on Anynet+ (HDMI-CEC) in the menu to activate it.
You will need to turn on ARC/eARC input on your speaker if your Samsung TV doesn’t support HDMI ARC, and HDMI will have to be set as your TV’s sound output if you use non-Samsung speakers. You can choose the Receiver (HDMI) by going to Home -> Settings -> Sound -> Sound Output.

7. Samsung TV HDMI Reset
You can use a factory reset to reset your Samsung TV HDMI ports.
If other methods haven’t worked, returning your TV to its factory settings may be a last resort, since it will remove all customization features, apps, and connected devices.
Samsung Smart TVs can be factory reset by following these steps:
- Go to Settings by pressing the Menu or Home button on your remote.
- Then go to General & Privacy.
- Then Reset.
- You’ll need to enter your PIN, which is by default 0000 (four zeros) for Samsung devices.
- In the popup, choose one final Reset.
In the video below, Samsung provides a video demonstration of these steps.
Using the Menu button beneath the Samsung TV’s logo, next to the Power button, will let you access the same menu options when you don’t have your remote.
Following the steps above involves pressing this and using the Volume + and -, or the Channel + and -, depending on your model.
Samsung TV Support and Warranty
Visiting Samsung’s warranty site will allow you to check the status of your warranty.
It is unfortunate that warranties usually last only one year unless you have already paid to extend them.
You should return your TV under warranty if it is under one year old, since HDMI errors can occur at any time.
To see if Samsung support can help, you can also contact them directly.
In this case, you are better off speaking directly with Samsung support, who can assist you directly with diagnosing your issue:

A live chatbot is available on their website 24 hours a day, 7 days a week, from 7am to 12am EST.
