Samsung TV Problems: 20 Known Issues (Explained & Solved!)

Have you faced problems with Samsung TV or thinking to buy? If you know how to solve Samsung tv problems on your own, you will escape many issues.

Here are the most common Samsung TV problems.

Samsung TV Showing a Black Screen

A television that displays a black screen, but whose sound works perfectly is a recurring problem that can indicate a connection problem or, more often, a backlight problem.

First, try using different sources (HDMI, USB, Smart Hub…). If the problem only occurs on one of the external sources, it is definitely time to change your HDMI cable.

If the problem persists, try an electrical reset:

  • Unplug your TV from the power outlet, wait a few minutes, then plug it back in again.
  • If the continuous TV showed a black screen, it probably means a problem with the backlight.
  • Samsung customer service or an authorized repairer will be able to fix this for you.

Samsung TV not turning on

A Samsung TV that no longer turns on is a problem that may be related to the electrical connection, the remote control, or a more serious problem.

If the red standby light does not light up or flashes

  • Try plugging your TV into a different outlet. Your power strip may be faulty.
  • If the problem persists, it will probably be necessary to contact a repairer. Several Internet users indicate that they had a problem with a motherboard that Samsung replaced under their warranty.

On the other hand, if the light is on continuously, check that the television switches on using the on/off button located on the television.

In this case, a simple replacement of the batteries in your remote control will be enough to solve the problem.

Samsung TV Turns On and Off in Loop

If your TV turns on and off randomly and in a loop, start by unplugging all peripheral devices connected to your TV and performing an electrical reset.

To do this, disconnect the power plug from your Smart TV, wait a few minutes, then reconnect it again.

If the problem persists, update your Smart TV software.

There are 2 ways to perform a software update for your TV:

  • via the internet, if the TV is connected 
  • or through the USB port.

The process depends on your model, so you’ll need to consult the TV’s user manual.

The problem is still not solved, in this case, reset your Samsung TV to factory settings. The option depends on the model, but usually, you will need to press the Home button on your remote. Then go to the Settings menu > General > Reset. Enter your PIN code (the default code is 0000 or 1111 if you haven’t changed it).

Samsung remote not working

In order to look for any troubleshooting related to a remote control problem, be sure to put new batteries in your remote control.

If despite this, you still have a problem with your remote control, you will need to reset it.

For that, it’s simple:

  1. Unplug your television and remove the batteries from your remote control.
  2. Wait a few minutes. Then put the batteries back in your remote control and turn your TV back on.
  3. If after a few minutes it still does not work, press the 2 Back and Play/Pause buttons simultaneously for 5 seconds. This will reset the TV and remote control gear.

Samsung TV turns/turning off by itself

To fix a Samsung TV turning off on its own, try a power reset. If the problem persists, reset your remote.

The 2 procedures are detailed earlier in this article.

Samsung TV showing a Green Screen

If your Smart TV is showing a green screen for a particular HDMI source, it could be due to the HDMI jack being used. If your source was connected via an HDMI 2.0 port (or UHD / 4K), connect it to another HDMI 1.4 type socket, then restart your TV as well as your source.

On the other hand, if your television only has HDMI 2.0 sockets, which is the case with most recent models:

  • Using the remote control, turn off Ultra HD mode by going to Settings > Pictures > Expert Settings > HDMI UHD COLOR menu.

Furthermore, if the problem is generalized to all sources, try an electrical reset. If the problem still persists, you will need to contact a specialized repairer to take a look at your TV.

HDMI port problem with Samsung TV

There are 2 types of problems you may experience with your HDMI ports:

If none of the HDMI ports are working, I recommend resetting your TV to factory settings. To do this, press the Home button on your remote control. Then go to the Settings menu > General > Reset. Enter your PIN code (the default code is 0000 or 1111 if you haven’t changed it).

If this persists, you will need to update your Samsung TV software.

If, on the other hand, the problem concerns a single HDMI port, it is very likely that your cable is defective and that it will have to be replaced. If not, the TV port is down, in which case try another port.

No Sound on Samsung TV

If your TV has no sound, but the picture displays normally, there are several potential sources.

If the sound is totally absent or very weak only on a particular source, check the volume of the device connected to this source. It may be set very low or in silent mode. This may seem obvious, but better check this first.

If the problem occurs with a source connected via HDMI, such as a Blu-Ray player or a game console, make sure that the cable is correctly connected and that it is not damaged.

If you are using your TV as a monitor for a computer, be sure to configure audio output to the HDMI port in your PC settings.

If a headset icon appears on your TV and you haven’t plugged one in, it’s possible that the jack is stuck. Try to unlock the switch gently with a toothpick for example.

ATV mode on Samsung TV

On some older Samsung TV models, it was possible to change from an ATV mode (analog antenna band) to a DTV mode (digital antenna band).

To do this, the change is made with a dedicated ATV/DTV button on your remote control or with a long press on button 1 on your remote control. If you don’t have either, look in your Samsung TV’s menu.

Since now all the programs are in digital mode, including DTT, the question no longer arises.

No Signal on Samsung TV

If your TV displays a message such as “No signal” or “Weak or no signal”, try one of these manipulations:

  • Check that the device (Internet box, game console or other) is on and that you are on the right source and not on an unused HDMI port.
  • If still no signal, restart your device.
  • If this still persists, unplug your TV from the electrical outlet, wait a few minutes and then turn the TV back on.

Problem with Netflix on Samsung TV

If you have a Samsung Smart TV and are having trouble getting the Netflix app to work, the first thing to check is your internet connection. It may seem obvious, but if your internet speed is low or non-existent, Netflix will not be able to function properly.

If the problem persists, I suggest reinstalling the app. To do this, go to your Smart Hub (the Home button on your remote). Go to Apps > Settings. Select the Netflix app and choose the Reinstall option from the menu.

At this level, there is undoubtedly a problem with the Smart Hub, resetting it could solve the problem.

To do this, go to the Settings menu > Assistance > Auto diagnostics and then reinstall the application. Enter your PIN to finalize the operation. If you haven’t changed it, it’s probably one of three: 1111, 1234, or 5555.

Smart Hub Update problem on Samsung TV

Sometimes, during an update of your TV’s Smart Hub (which can be automatic or manual), your Smart Hub becomes inaccessible.

The first thing to do is to update the Smart TV through the Settings menu > Support > Software update > update now.

If during this update phase, you have an error message indicating a network problem, change your connection mode. If your TV is connected via wifi, try connecting it with an Ethernet cable.

Finally, you can try to apply the update via a USB key. The option is available in the Settings > Support > Software Update > Update Now menu .

You can find the latest version of the Smart Hub corresponding to your TV on the Samsung website.

Samsung TV turning on by itself

Good news, you are not the only one having this problem. To make an accurate diagnosis, the first thing to do is to go to the event log of your TV available in the Support > About this TV menu.

This menu gives you access to your television’s authentication information, but also when you scroll down, to the events that caused the television to turn on with the date and time of each event.

If the event in question is HDMI CEC (also called Anynet+), you can deactivate HDMI CEC through the System > Anynet+ menu.

On the other hand, if the event in question is a WoL (Wake on Lan), disable your network devices one by one to detect which one is causing this problem.

Application that no longer works on Samsung Smart TV

If one of the applications on your Samsung Smart TV does not launch or systematically stops after opening. There are different solutions to explore.

First, try an electrical reset. This will allow your television to empty its memory space or get rid of any residual electrical charge which may cause minor malfunctions.

To do this, press and hold the power button until the TV turns off and then back on.

Another way to do this is to unplug the TV from the power source and wait 30 seconds before plugging it back in.

If this does not solve the problem, you reinstall the application which will allow you to delete any obsolete data which could explain the malfunction.

To do this, go to your Smart Hub (the Home button on your remote). Go to Apps > Settings. Select the application and choose the “Reinstall” option from the menu.

You can also delete the application first and install it again.

If the app still does not work, it may not be compatible with the version of the Smart Hub.

The update of the Smart Hub is done in the Settings > Support > Software update > Update now menu.

Your Smart TV will check for available updates and offer to install them if there are any.

If there are firmware updates, your TV will download them automatically.

Note that it is recommended to perform a power reset after installing an app or Smart Hub update.

Vertical or Horizontal Band problem on Samsung TV

If your screen displays one or more vertical or horizontal bands, the first thing to do is to test with a different source.

If the problem disappears, it is probably related to the device or the connection cable.

If the problem persists, you can run an image diagnostic.

To do this, go to the menu Settings > Support > Automatic diagnostics > Launch image test.

If the lines disappeared during the diagnosis, the problem is with your image settings.

In this case, restore your TV to its original settings using the Settings > Picture > Expert settings > Reset picture settings menu.

If the bands are still there, approach a Samsung-authorized repair center, it is probably a problem with the panel.

Samsung TV Showing a Blue Screen

Your Samsung TV displays a blue screen for a particular HDMI source, it could be due to the HDMI cable used.

First, try restarting your device, this might fix the problem.

Then try with another HDMI cable or another HDMI socket on the TV. The socket used may be faulty.

On the other hand, if the problem is generalized to all the sources, try an electrical reset.

Samsung TV showing white screen

If your TV displays a white screen, but the sound works perfectly, check that the problem is systematic on all sources and channels.

If the problem is widespread, try an electrical reset: unplug your TV, wait a few minutes, then plug it back in again.

If the TV continues to show a white screen, it likely indicates a T-CON issue that an authorized repairer can take care of.

Bluetooth problem

The most obvious solution to a Bluetooth connection problem is that your television does not have this technology.

If, on the other hand, you notice cuts in your device, I recommend that you perform an electrical reset on your Samsung TV as well as your device connected in Bluetooth mode.

Screen mirroring issue

Sharing your Smartphone’s screen wirelessly with your Samsung TV may not work and this may be due to various reasons.

If this is the first time you have tried to set up mirror mode on this TV, remember to check that this feature is indeed available on this model.

Then, check that your phone detects your TV and that it appears in the list of TVs with which you can start a screen share.

Finally, try restarting your TV as well as your Smartphone and make sure both are connected to the same Wifi network.

Samsung TV Picture Too Big

If the image of your Samsung TV is too stretched as is the case in the photo below where the edges of the image no longer appear, it is certainly due to an incorrect setting of the aspect ratio used.

To correct your picture format, press the Home button on your remote. Then go to the menu: Settings > Image > Image format settings. Then change to the format that best suits your TV (usually 16:9 or 4:3).

Samsung TV brightness problem

Sometimes the image from your Samsung TV is not bright enough or the image is not evenly backlit as seen in the picture below.

If the picture on your Samsung TV isn’t bright enough, the problem may be with your picture settings.

First, try another picture mode among those offered in the Settings > Picture > Picture Mode menu, such as Standard mode or Dynamic mode.

If the problem persists, the next action is to restore your TV to its original settings.

To do this, go to Settings > Image > Expert settings > Reset image settings menu and confirm the action.

Still not resolved? the culprit may lie with your TV’s energy-saving features.

There are several of them and you will deactivate them one by one in order to find the culprit.

To do this, go to the  Settings > General > Eco Solution menu and start by deactivating ambient light detection, which adjusts the brightness according to the ambient lighting.

Then increase the minimum backlight level which might be too low.

Finally, deactivate Eco Mode if this last feature is activated. This should fix your lowlight issues in most cases.

On the other hand, if you notice that the image is not backlit evenly as is the case in the photo below, the problem is probably more serious.

We speak of light leakage or loss of light when part of the backlight escapes and this is characterized by the loss of brightness.

In this case, I advise you not to turn your TV back on to avoid aggravating the situation and to contact Samsung customer service or an authorized repairer.
