The most common cause of this issue is a faulty isolation transformer, a device that helps control the amount of power running to your TV. If the transformer is damaged, it can cause one side of the screen to become darker than the other.
Additionally, a problem with the television’s backlighting can also cause this issue. If the backlighting is uneven, it can cause one side of the screen to be darker than the other. Finally, other issues like improperly adjusted contrast settings or incorrect color settings can also cause this issue.
If you are unable to diagnose or fix the issue yourself, it is best to bring your TV to a qualified service technician to have it properly repaired.
Why is half the screen black on my Samsung TV?
The most common cause of a half-black screen on a Samsung TV is a failed panel, which can happen when the device has been powered on and off too often. This can cause the panel to overheat and then fail, resulting in just half the screen appearing.
It can also be caused by any kind of physical damage, like a crack in the display panel. It can also be caused by a defective T-con board, which is the circuit board that controls the TV’s picture. If that is the case, then it will likely need to be replaced.
Additionally, a faulty backlight inverter board or faulty LED strips connected to the TV can also cause this type of issue. If none of these solutions resolves the issue, then it is best to contact Samsung customer service for further assistance.
Why is half my TV screen dark?
If you notice half of your TV screen is dark, then it is likely due to either an issue with your TV’s video settings or an issue with the connection between your TV and another device.
First, check if the video settings on your TV are set correctly. Make sure the contrast and brightness settings are at or near the middle or pre-set positions. If you keep the TV on for an extended period of time, the contrast and brightness may start to decline and cause the dimming of one half of the screen.
You can adjust these settings as needed and also enable auto-adjustment, if available.
If adjusting the video settings does not help, then there may be an issue with the connection between your TV and the device you are using. Make sure the cables between the device and the TV are firmly inserted into the correct ports.
Also, check to be sure the device is displaying a signal and that the cable is receiving the signal correctly.
If you are still having the issue, you may need to reach out to a certified technician to check the hardware and repair any issues.

How do you know if your TV backlight is broken?
In order to determine if your TV backlight is broken, you need to perform a few tests. First and foremost, visually inspect the TV to check the backlight illumination. If it appears dimmer than normal and/or appears to lack full brightness, then this may be a sign that the backlight has failed.
Another test to check for a broken backlight is to look for dark spots or blemishes on the screen. With a backlight failure, you may notice that there are certain areas of the screen that are significantly darker than others, or have a sort of discoloration or tint.
You can also use a flashlight to test for a broken backlight. Turn off the TV and fully darken the room. Shine the flashlight on the screen and observe what happens. If you notice changes in screen brightness, then this could indicate a backlight issue.
In some cases, your TV may turn on but the picture may be completely black. This is another indication of a failed backlight. If none of the above tests indicate a broken backlight, then it could be some other malfunction in the TV.
How do you fix dark shadow on LCD TV?
Fixing a dark shadow on an LCD TV typically involves adjusting the TV’s backlighting. This can be accomplished by using either the on-screen menu or the television’s manual.
First, power on the TV and find the backlight setting, either through the menu or the remote. If you are using the on-screen menu, you may need to navigate through several options to get to the backlighting menu.
Each make and model of television is different, so you may need to consult your television’s user manual if you are having difficulty finding the backlighting menu.
Once you are in the backlight menu, you may need to adjust either the overall backlight, or the individual sections of backlight on the display. If your television has a single level of backlight, raising it above the factory setting can help to resolve the issue.
If your TV has multiple sections of backlight, such as one for each corner, you may need to raise each section one at a time to resolve the issue.
Raising the backlight will draw more power and result in a slightly lower image quality, so it is important to adjust the backlight until the issue is resolved while considering energy efficiency and image quality.
If adjusting the backlight does not resolve the issue, you may want to consider investing in a new LCD TV. There are a variety of sizes, styles, and features available to suit any budget. Replacing the television may resolve the issue and provide you with a higher quality display.
What causes TV screen darken?
The most common is when the backlighting on the display has gone out. This happens when the light-emitting diodes (LEDs) that form the backlight for the screen have burned out, and these LEDs are what provide the brightness for the picture.
Another possibility is that the backlight LED driver circuitry is malfunctioning, causing an insufficient voltage to reach the backlight, resulting in a picture that is too dark.
Additionally, some televisions have a feature called “Ambient Light Detection” or “Auto Brightness Limiter” that can sometimes cause the picture to dim. When enabled, this feature reduces the backlighting of the TV when it detects low background-light levels and thus reduces energy consumption.
This can be convenient for automatically reducing the brightness of the television when the environment is dim, e. g. , in a dark room or late at night, however, it must be disabled if you want a bright picture.
Sometimes, a dark picture can also be caused by a malfunction in the television’s power supply circuitry or by a bad connection between the power source and display. Thus, it’s best to check all the electrical connections and, if possible, inspect the power supply circuit for any damage.
Can you fix a backlight on a TV?
Yes, you can fix a backlight on a TV. To do this, you will need to power off and unplug the TV. Next, you will need to open up the back panel of the television by removing the screws that are holding it together.
Once it is opened, you will be able to access the backlight component, which will likely look like a thin black board. You will then need to check the connections of the backlight to make sure they are all secure, as loose connections can cause the backlight to fail.
If the connections are secure, then you may need to replace the backlight entirely. To do this, you will need to locate a replacement backlight that is compatible with your TV model and carefully install it, ensuring that all the wires are properly connected.
Once the new backlight is in place, you can reassemble the TV and power it back on to ensure the backlight is working properly.
How much does it cost to replace backlight on TV?
The exact cost to replace a backlight in a TV can vary widely depending on the type of TV, the size of the backlight, and the labor costs associated with the repair. Generally speaking, backlight replacement on modern LED HDTVs can cost anywhere from $150 to $450, with most repairs falling at the lower end of that range.

For older CRT or plasma TVs, since these parts are no longer manufactured, the cost of obtaining a refurbished part or a used device that contains the same backlight can be significantly higher, in some cases even exceeding the cost of a new TV.
How long do TV backlights last?
The lifespan of a TV backlight will depend on a variety of factors, including the type of backlight used and the amount of time it’s used each day. Generally, LED backlights are known to have the longest lifespans, and have the potential to last upwards of 60,000 hours depending on the usage.
This means LED backlights can last up to 7 years with 8 hours of daily use, or up to 14 years with 4 hours of daily use.
On the other hand, CCFL (cold cathode fluorescent lamp) backlights are generally seen to be less reliable and have a lower lifespan, usually around 15,000-30,000 hours. This means they can last up to 1.7-3.
4 years with 8 hours of daily use, or up to 3.4-6.8 years with 4 hours of daily use.
Overall, the lifespan of your TV’s backlight will depend largely on the usage and the type of backlight used. However, with proper maintenance and regular use, TV backlights can last quite a long time.
Why does my TV have a shadow on one side?
A shadow on one side of your TV is likely caused by an obstruction or uneven reflective surface in front of the TV. This could be due to the location of the TV relative to a window, lighting fixtures nearby, or furniture obstructing the TV’s view.
It may also occur when the picture on the TV set is out of balance due to focusing issues, a faulty convergence circuit, or other electronics issues.
If the shadow appears when the TV is turned off, relocating the TV and/or rearranging nearby objects may help reduce the obstruction. To check for focusing issues, you can activate the degaussing feature in the TV’s menu.
This should help adjust the balance and symmetry of the picture. If this does not work, then it is recommended that you call in a professional to diagnose and fix the underlying electronics problem.
