Samsung TV screen being so dark <\/a>,I have got you covered here as well.<\/p>\n\n\n\nIf you face Samsung LED TV lines on screen problem, then the TV has a connection or processing problem. For vertical lines on Samsung TV, check if the panel is connected properly. It could also be that the scalar T-Con, PCB, or Cof -IC is faulty. For horizontal lines on Samsung TV, restart the device, update the firmware, and factory reset if necessary.<\/strong><\/p>\n\n\n\nBefore you freak out and think, “I don’t understand a single word you are saying, James,” don’t worry! I will take you on a step-by-step guide to fixing Samsung TV lines on screen<\/strong> without needing to call a technician. Let’s get started!<\/p>\n\n\n\nWhat Causes Vertical Lines on Samsung TV?<\/strong><\/h2>\n\n\n\nIf you face the “Samsung TV vertical black lines on screen” <\/strong>issue, know that multiple factors contribute to this problem. As mentioned above, the processing or wiring can be faulty, affecting the pixel data sent to the TV. There are typically two major reasons for vertical lines on Samsung TV: a processing problem or a bad connection.<\/p>\n\n\n\nIf vertical lines on Samsung TV <\/strong>are caused by processing problems, you have a faulty processing board, Cof-IC, T-Con, or scalar PCB, which disconnects the TV from the screen and requires a professional’s help. On the other hand, if the problem occurs due to a bad connection, there are easy fixes available, which I will discuss in detail.<\/p>\n\n\n\nLet’s look at the common causes of Samsung TV lines on screen.<\/strong><\/p>\n\n\n\nLoose Cables<\/strong><\/h3>\n\n\n\nLoose or mismatched control board cables and connections can cause Samsung TV lines on screen<\/strong>. You need to get the loose wire fixed. Moreover, you could also have antennae problems, or there is a faulty component within the TV that cannot make a stable connection. A quick and easy Samsung TV vertical lines fix <\/strong>to tap the back. This will only work temporarily, but at least you can finish your episode in peace.<\/p>\n\n\n\nDamaged Screen<\/strong><\/h3>\n\n\n\nVertical lines can also appear on Samsung TVs due to excess moisture or water that damages the TV screen.<\/p>\n\n\n\n
Cof-IC Connection Issue<\/strong><\/h3>\n\n\n\nIf you are facing a Cof-IC connection issue, the TV screen is not getting the right pixel information. As a result, vertical lines on Samsung TV appear. If the Cof-IC is damaged, replace it via a tab bonding machine and then connect the TV components to the TV screen.<\/p>\n\n\n\n
I would however recommend not doing it yourself but calling a technician.<\/p>\n\n\n\n
Nearby Devices<\/strong><\/h3>\n\n\n\nNearby devices can interfere with the signals and cause vertical lines on Samsung TV models<\/strong>. For instance, if a speaker, mobile phone, or microwave is placed near a TV, you should move these devices and see if this resolves the problem.<\/p>\n\n\n\nFaulty T-Con Board<\/strong><\/h3>\n\n\n\nIf you see a single vertical line on TV screen<\/strong>, it is due to a faulty T-Con board. The T-Con board receives pixel information from the scalar PCB. A processing or connection error causes a single vertical line on TV screen to appear. It can even cause images with blurred edges. <\/p>\n\n\n\nMoreover, when the TV frame rusts and this rust spreads to the cable connections, it can cause Samsung TV vertical color lines <\/strong>to appear. A damaged T-Con board module also causes this problem.<\/p>\n\n\n\nTypes of Vertical Lines on Samsung TV Screen<\/strong><\/h2>\n\n\n\nWhen vertical lines appear on your Samsung TV, you need to note what types of lines appear. The anomaly or shape of the lines can help identify the cause and assist in getting rid of them. Below, I have listed some of the common vertical lines on Samsung TV.<\/strong><\/p>\n\n\n\nStraight\/Stationary Lines: Straight or fixed lines that do not move indicate that the issue is within the internal workings of the TV. Wavy Lines: A bad connection leads to wavy lines that move or sway. Ghosting: A TV screen is ghosting when multiple images are stacked on top of one another, and it appears like a double-exposure image. A bad connection also causes this issue.<\/p>\n\n\n\n
5 Easy Samsung TV Vertical Lines Fix – What Can You Do?<\/strong><\/h2>\n\n\n\nNow that you know what causes Samsung QLED lines on screen<\/strong> and their types, focus on the solutions.<\/p>\n\n\n\nRemove and Reconnect All the Cables<\/strong><\/h3>\n\n\n\n <\/figure>\n\n\n\nOne of the most common causes of vertical lines appearing on Samsung TV is bad connections. This is especially common if you live in areas with high humidity or harsh temperatures that lead to corrosion.<\/p>\n\n\n\n
One way to fix this is to remove all connections from your TV and reconnect them. Another way is to check the HDMI cables. If lines appear on the TV, change the input and see if they disappear. If so, you need to replace the HDMI cable.<\/p>\n\n\n\n
Reseat the Internal Connections<\/strong><\/h3>\n\n\n\nSometimes, the vertical lines still appear on Samsung TV even after reconnecting all the cables. Don’t worry! Just tap the back of the TV and see if the lines disappear. If the lines disappear when tapping at a certain point, you have an internal connection issue.<\/p>\n\n\n\n
Normally, I wouldn’t recommend opening the back of your TV and reseating all connections, as you can do more damage than good. But if you feel confident, go for it. Or you could avail your Samsung TV warranty and reach out to their team to get the vertical lines on Samsung TV issue fixed.<\/strong><\/p>\n\n\n\nDo a Picture Test<\/strong><\/h3>\n\n\n\nIf the lines are constant, perform a picture test. This can check the internal components and connections for you and determine what’s causing the issue. Select the “self-diagnosis” option and then run the test. It will take a couple of minutes, tops.<\/p>\n\n\n\n
If the lines disappear and reappear during the test, they can be fixed. If the vertical lines remain on the screen throughout the test, you need to invest in a new Samsung TV.<\/p>\n\n\n\n
Update the Firmware<\/strong><\/h3>\n\n\n\n <\/figure>\n\n\n\nIf the Samsung TV’s firmware is out of date, it can cause vertical lines on TV screen. Update the firmware, re-examine the image, and see if the issue is resolved.<\/p>\n\n\n\n
Reset Your Samsung TV<\/strong><\/h3>\n\n\n\nYou can try resetting your Samsung TV to its factory default settings if nothing else works. The problem could be in the software; by resetting, you can resolve that issue and restore it to its original setting. Remember that you lose all data and apps downloaded by resetting your Samsung TV. You will also need to sign in again to your services.<\/p>\n\n\n\n
How To Reset Your Samsung TV<\/strong><\/p>\n\n\n\nOpen settings and select the “general” option.<\/li> Select “reset.” A pop-up will open, asking for your PIN (the default is 0000). Then, select reset again.<\/li> Click on “ok,” and your TV will restart.<\/li><\/ol>\n\n\n\nI hope these Samsung TV vertical line fixes could get the job done. If not, you will need to call in a technician.<\/p>\n\n\n\n
However, there is another problem we need to discuss. Remember at the start of this article, I mentioned both vertical and horizontal lines appearing on Samsung TV?<\/p>\n\n\n\n
If you thought both had the same solutions, you were wrong. Let’s move to the horizontal lines on Samsung TV fixes.<\/p>\n\n\n\n
What Causes Samsung TV Horizontal Lines on Screen?<\/strong><\/h2>\n\n\n\nThere are several reasons for a thick black line on Samsung TV screen<\/strong>. A primary reason for this is a graphic card failure. The graphic card is an essential part of the TV and ensures that the signals are converted into pixels so you can watch your favorite TV shows without disturbance. Below I have listed some common reasons for horizontal lines on Samsung TV.<\/strong><\/p>\n\n\n\nIncompatible Image Resolution: If you notice Samsung TV black line on screen<\/strong>, the image resolution could be a major reason. Small or big images, different from the TV’s resolution settings, can lead to lines appearing on the screen or blurred images.<\/p>\n\n\n\nCable Issues: If you have not connected the cables between the smart TV and the hub, it can cause black lines to appear on the TV. The simple solution involves removing the cables, waiting a few minutes, and plugging them back in. Broken Panel: A gated driver is part of the TV’s motherboard and is responsible for powering the display screen. Any fault in the gated driver leads to thick black lines on the screen and requires a professional technician to replace it.<\/p>\n\n\n\n
Outdated Firmware: When your software is out-of-date, it won’t be compatible with the latest high-resolution pictures. This can also lead to thick black lines on the screen. However, simply updating the software fixes the problem.<\/p>\n\n\n\n
Now that you know what causes Samsung TV black line on screen<\/strong>, it’s best to move on to the solutions.<\/p>\n\n\n\n4 Simple Fixes for Samsung TV Horizontal Lines on Screen<\/strong><\/h2>\n\n\n\nRemember, some of these solutions are similar to what I recommended for vertical lines on Samsung TV. Thus, cover all your bases and be prepared for any problem.<\/p>\n\n\n\n
Power Cycle the TV<\/strong><\/h3>\n\n\n\nThe most common and easiest way to fix Samsung TV horizontal lines on screen<\/strong> is to power cycle the TV. Power cycling involves unplugging the TV from the wall socket, waiting for 60 seconds, and then replugging it.<\/p>\n\n\n\nWhen the TV is unplugged, hold the power button on the Samsung TV for 30 seconds; this will help soft reset the TV and refresh its operating system to clear out any bugs hindering its performance.<\/p>\n\n\n\n
