Samsung TV no signal

For Samsung TVs to operate well and provide the best experience, HDMI is a crucial component. As a result, the TVs use HDMI as their standard connection path to other devices such as set-top boxes, gaming consoles, video projectors, and streaming players among other devices.

This means that when your Samsung TV isn’t recognizing the HDMI input or you’re getting the no signal error after plugging in your HDMI, you will not be able to enjoy any external services. This is a problem that calls for immediate attention.

Why Won’t My TV Recognize My HDMI? (& Why Does It Say No Signal)

Consider this, you have been using your Samsung TV for some time now, connected to various devices, and then all of a sudden, it does not recognize the HDMI and it says no signal. Or you try to introduce a new device, and when you plug in the HDMI, the TV does not recognize it.

Several factors may cause this kind of problem. You should be able to understand what these factors can be and how to fix them. Read below to find out more.

1. The Correct Source Hasn’t Been Selected

The Samsung TV is designed in a very systematic and smart manner. When Samsung make their TVs, they understand that you will have several sources for your content.

You will need to use several devices on your TV to provide you with the type of content you enjoy. That means you may have your gaming console connected, top-box, or streaming player, among other sources.

At the same time, you will have all these sources connected to your TV. When watching, you have to select the right source you would like to watch. For example, if your TV has three HDMI ports, and is all connected, you must select the appropriate source for it to play what you would like to connect.

When you correct the wrong source, you are likely to get this kind of error especially if there is nothing connected. So, do not be in a hurry, but make sure you do it right.

Fix – Choose the Correct Source

You must select the correct source for your TV to work exactly how you want it to. If you have connected your streaming player to HDMI 1, then do not select HDMI 2 on your TV and expect it to work. You must select the same HDMI 1 on your TV.

You can select the correct source on your Samsung TV using the remote’s source button. Here are the steps to follow if your remote has a source button.

1. Take your Samsung TV remote gadget.

2. On the remote, look for a button named “Source”. The button should be on the right side, upper corner.

3. Now, click on the button to get the list of sources you should select from.

4. Once you get the list of sources, check at the back of the TV, and see the HDMI you are using and for which device.

5. Now select that source on the TV screen.

Here is how to select the correct source using the Samsung TV menu. If your remote does not have the source button, you can also use this method.

1. Use your remote and press on “Menu Button”.

2. The TV will display the Main menu.

3. Navigate through the menu and look for “Source”.

4. Select the “Source” option.

5. Here you will find a list of devices that are connected.

6. Identify the HDMI port you are using and select the right device source.

2. Poor HDMI Cable Connection

When your Samsung TV is not recognizing the HDMI cable, there could be a possibility that there is a poor HDMI cable connection and you do not know about it. Note, that the HDMI cable is the priority in this case and unless there is a good connection, there will be errors detected.

HDMI cables are designed to transmit a high amount of data within a very short time and they are quite sensitive. Your Samsung TV is also sensitive to the behavior and the performance of your HDMI cables.

So, if you have not been careful about the condition of your HDMI cable, this could be the reason your Samsung TV is not recognizing it. Several reasons may be causing a poor HDMI connection.

It can be a loose connection, faulty HDMI cable, broken cable, faulty HDMI ports, or even bent cables that are not able to transmit data as expected. Here are some of the ways to fix this problem.

Fix – Reconnect HDMI Cable

It is possible that your HDMI cable is not connected very well. It could also be lost and you do not know. This can be a case if you have been having some activities around your TV and you happen to touch the cable. You may also have kids in the house who can touch the cable and you fail to know.

Either way, you need to look at the cable connected to your TV. Carefully check the cable and make sure it is well plugged into the TV as well as the other device you are using. It is advised you remove the cable and reconnect it firmly and be sure.

Fix 2 – Switch Ports

Are your HDMI ports working properly? Just like in other devices, the HDMI ports on your Samsung TV may fail and stop working without you knowing.

So, once you have checked the HDMI cable connection and it is okay, then you realize you are experiencing the same problem, it is time to go to the ports.

Switch to a different port and check how the TV will perform. If there is a third port, you should also check it. This is because failure in one port does not necessarily mean failure in all other ports.

Fix 3 – Use a Different HDMI Cable

At this point, you have checked the connection of the HDMI cable, and you still get the same problem. You have also switched the ports and the TV still can’t recognize the HDMI. So, what else could be the problem?

There are chances that actually the HDMI cable you are using is the problem. Your HDMI cable may not be working on your TV for several reasons. The cable might be damaged, or you may be using an incompatible cable.

The only way to find out is by using another cable. So, look for a different HDMI cable that meets the requirements of your devices and try using it.

Fix 4 – Replace HDMI Cable

It is not all the time you will have a chance to get another cable from your house or friend to try it on your TV. At the same time, you may examine the cable and find signs that show the cable is damaged and you need to get a new one.

If you notice the cable having some breakages, heavily bent sections, corrosion, or even a short circuit, then you have to replace it (view on Amazon). Note that in some cases the damage might be inside the cable components and you won’t know.

When getting a replacement HDMI cable, make sure you get a high-quality cable. It is recommended to buy a 4K speed HDMI cable for better performance.

3. Issue with the External Device

Another reason your Samsung TV is not recognizing your HDMI cable could be the external device you have connected it to. People connect their TVs with a variety of external devices. That does not mean that these devices are always in good operating condition.

Think of it as using earphones on your phone. If it is not working, the issue could be the earphones or the phone.

So, for this cause, your external device could have a problem that does not allow your Samsung TV to recognize it. It is an issue you have to check and address. It can be any type of device. Here are some of the methods to use.

Fix – Connect a Different External Device to See if it Works

First, you need to check whether the external device you are using has a problem. The device might have a problem but you do not know. However, connecting a different external device will enable you to see what the problem is.

It does not have to be an exact similar type of device. What this means is, that if it is a gaming console, you do not have to connect to another gaming console. You can get another device that will use the same HDMI cable and see whether your TV will recognize it. If the new device works well, then you will know the first one had an issue.

Fix 1 – Change the Devices to Turn on Sequence

Changing the way you turn on your devices in some cases can solve the problem of your Samsung TV not recognizing the HDMI. Consider this, if you turn on the TV and then turn on the rest of the external devices you can change this.

This process involves changing the way you do the whole process. Basically, you need to take note of how you turn on the devices and change the order. If this process works, then you will have to stick to it.

Fix 2 – Check for Errors with External Device

Sometimes, you may be using a complex device that may bring this kind of problem if it has some errors. An example is when you are using a streaming device or a gaming console. There are so many external devices that use HDMI cables to connect to your Samsung TV.

Fix 3 – Restart External Device

Many external devices such as gaming consoles and streaming devices may have errors that can be fixed by restarting. The device may be experiencing bugs that are stored in the system. So, turn off the external device, wait for around 1 minute and turn it on again. This process should initiate a fresh connection with the TV.

Fix 4 – Reset External Device

Resetting your external device is also a good way to fix glitches in its system. Many external devices will clear errors and start the process all over again.

To reset your external device, you have to research the right process to follow to do it. However, if you do not know, follow the following steps.

5. Port or HDMI is Clogged

Dirt is bad. Dirt is bad even for electronic devices. When your TV stays in a dusty area for a long time, there are consequences to that that you may not even know about.

Your Samsung TV HDMI ports are prone to dust, foreign materials, and any time of clogging. When dust and other debris settle on the plates of your HDMI ports, they create resistance that makes it difficult to connect with the HDMI cable.

It is not just dust, there are many other foreign materials that might land on your TV’s HDMI ports and cause significant clogging. Materials such as loose fibers, can also land on those ports and prevent the HDMI cable from connecting.

You may also have not used the ports for a long time and you never know what could be there. If you have kids, they may also have touched the ports and kids can easily insert objects there. So, you need to check your HDMI ports for any kind of clogging.

This can also be an issue with HDMI cables. When you leave your HDMI cables carelessly unattended or lying on the floor, they will collect dirt and other materials that can clog them.

Fix – Clean Out HDMI Port and HDMI

The only solution you have for fixing your HDMI and HDMI ports when they are clogged is to clean them out. However, the first thing you have to note is that HDMI ports and cables are very sensitive.

Follow these steps to clean out your HDMI ports and cables.

1. Make sure you have turned off your Samsun TV.

2. Acquire a lint-free piece of cloth. This is necessary as it will not leave fibers in the ports.

3. Also, get denatured alcohol. It is good instead of water. Do not use water.
