Why is my TV screen so dark?

The picture on a TV screen can appear too dark if the theatrical mode is turned on in the settings, if the backlight is placed behind the LCD panel or when power saving mode is set to the high setting.

  • There are different display modes on a TV, which we normally do not adjust. There are different modes for animated shows, soap operas, and even for different movies. In most of the TV sets, the display mode is set as the darker mode by default so that your eyes are not hurt.
  • In most cases, there are two modes, namely ‘theatrical’ and ‘neutral.’ The ‘theatrical’ mode is selected as the default, but you should choose the ‘neutral’ mode if you want a clearer vision of what is happening on the screen but do not want to hurt your eyes.
  • In some of the less-advanced models, the screen is normally lit up by a backlight. This backlight is placed behind the LCD panel and is not good at creating contrast, and as a result, the screen appears too dark.
  • Many times, by mistake, you might set the power saving mode as high. This is also a common reason behind getting a dark TV screen.

 

Why is half of my TV screen dark?

The reason for one half of a TV screen being too dark can be due to a faulty HDMI cable, faulty backlights or interference from connected external devices.

  • This kind of problem can occur for many reasons. The most common cause is that the backlights are not working properly. These lights can only be half-lit on one side, making the screen appear dark on that side.
  • It has often been found that there is some problem with the network broadcast your cable company is using. However, this is a very rare instance.
  • In many cases, the problem is occurring due to a faulty HDMI cable. If there is some kind of fault with the HDMI cable, then the signal given by it to the TV may be wrong, causing half of the screen to appear dark.
  • The problem with HDMI can also happen due to any other external devices connected to the TV, so check all the external devices connected before proceeding to dismantle the TV screen.

 

Why is my TV screen dark on the left side?

If your TV screen is dark on the left side, there may be a fault with the signal or the backlight.

  • First of all, check the HDMI cable connected to the TV and the cable signal of your network providers. Some fault in the cable or the network may be the cause.
  • If there is no problem with the external devices and cables, then the screen’s backlights may have burned out or stopped working on the left side. This causes the left side of your TV to appear dark.
  • If the problem is true with the backlights, the only feasible solution is to get the TV replaced. This is because the cost of getting new backlights is the same as that of a new TV, and not to mention that if the screen gets damaged in the process, you would need to replace it as well.

 

Why is my TV screen dark on the right side?

You may have faced the problem where the TV screen is dark on the right side. This can happen because:

  • There might be a problem with the power outlet or the external devices connected to the TV.
  • First of all, you need to rule out that there might be something wrong with the TV. To do this, try running the TV through other power sources and connecting other external devices. If the problem disappears, then there is nothing wrong with your TV, and the problem is with the devices or the power source connected to the television.
  • In some of the newer models, there are options for diagnosing any problem with the HDMI cable or other connected devices. Make use of that system to pinpoint the issue.
  • If the problem does not go away, then the cause is the backlights burning out on the right side. In this case, you wouldn’t have any choice but to get the TV replaced as the cost will be too high, not to mention the potential damage that can happen to your screen.

 

Why is my TV screen dark at the bottom?

This problem is very common for people using smart TVs or PCs connected to their televisions. If you are one of them, then you are no stranger to this issue.

However, the reason is very simple for this problem:

  • Generally, when you are using your TV connected to a PC or some smart box, it just acts as a screen. The source’s device completely controls the signal and its nature.
  • In most cases, there are some discrepancies in the signal sent by the source to the TV, which causes a black bar or a dark patch to appear on the bottom of the screen.
  • The easiest and the most common solution is to restart your TV. If it does not work, try doing the same again after taking out all the wires and cables and devices connected to the TV. In the majority of cases, this solves the problem.
  • Use the diagnostic tool on your TV to pinpoint the problem. The most common cause of this problem is the HDMI cable. This should make the dark area disappear.
  • However, if you cannot find any problem with the devices or the cables connected to the TV, the problem is with the TV. If this is the case, then you are left with no choice but to get it replaced. You should consult the service center and experts before you dismantle it since the LED screens are very delicate and can be easily damaged. You do not want to incur extra costs for the screen.

 

Why is my TV screen dark at the top?

Like the problems mentioned above, you might also face the dilemma of a dark band at the top of your TV screen. The reasons behind this are:

  • In the majority of cases, it is due to the other internet devices connected to your TV. This is a common problem for smart TV’s. Either the devices are sending some wrong signals, or the HDMI cables used for the connections are faulty.
  • First of all, try using the diagnostic tool for determining if there is any kind of fault with the HDMI or the signal.
  • If the tool shows any fault, then you will know exactly what to fix, but if it does not, then you need to reboot the whole system. The best way to do this is to disconnect all the TV cables and devices and turn it off and reset it. Then turn it on without the connections, turn it off, and turn on with all the connections. Normally, this will fix the problem.
  • If none of the above methods work, then the problem is most likely with your TV set and will need to get replaced.

 

Why is my Samsung TV screen so dark?

If you are an owner of a Samsung TV, you might not be a stranger to the dark screen problem. This problem is different from the previously mentioned ones. In those situations, the darkness on the screen was like patches, but in this case, the whole screen is visible but darker. This problem is more common in the newer models than in the older ones.

The main reasons for this are:

  • Most of the modern Samsung TV models come with a feature known as the Eco-sensor. This is simply a sensor for ambient light settings. So when you are watching TV in a dimly lit room, the Eco-sensor turns down the brightness, and the exact opposite happens when you are in a brightly lit room. You can turn off this feature in the settings.
  • Sometimes the power-saving mode may be set high by default, which turns down the screen’s brightness. This might cause your TV to be too dark. Turn it off, and the problem is solved.
  • If none of the above-mentioned reasons are valid for your TV, then check your network provider’s signal strength. Also, check for any pending updates for your TV’s software.
  • If none of the solutions work, then contact consumer support before engaging in any kind of dismantling to repair hardware.

  • If none of the above solutions work, then your best bet is to reset all TV settings. Use the mute button three times on the remote to run an AV reset, which should fix the dark screen problem.
  • If the problem persists even after running a reset, there is something problematic with the TV, and you will need to contact consumer support.
