Are you noticing horizontal lines on your Samsung TV screen? This is an issue that often arises. In this article, we’ll help you fix it so you can enjoy crisp, clear pictures once again!
Before anything else, double-check that all HDMI and signal cables are securely seated with no oxidation on their contacts. Finally, gently squeeze the bezel next to the horizontal line to see if any gate drivers have come loose.
1. Loose or Damaged HDMI Cable
If you’re noticing horizontal lines on your Samsung TV screen, there could be several reasons. Some issues are straightforward to rectify while others require more effort.
Before anything else, inspect the HDMI cable to make sure it’s in good condition. A loose or damaged HDMI cable can lead to issues with resolution and picture quality. Make sure it’s securely seated with no oxidation or corrosion on its pins, and confirm that your TV receives consistent power from its wall socket.
Next, ensure the input ports on your Samsung TV are correctly selected. If an input has been accidentally switched or reconnected, this could be the issue. To test another option, scroll through your options and try another to ensure you’re receiving a proper signal.
If the cables are connected properly and yet your display still appears blurry or low resolution, an internal issue may exist. A damaged HDMI cable could potentially lead to issues with the internal circuitry of your television set which would explain why a bad image appears onscreen.
If the HDMI cable is malfunctioning, try taking it out and reinserting it. If this doesn’t solve the issue, then you may need to replace your HDMI cable.
A malfunctioning HDMI cable can also result in issues with your television’s input port. This is because the HDMI cable needs to transmit signals from a device to the main input port located on the back of your Samsung TV.
Damaged input ports can lead to problems with the TV’s internal T-Con board, which controls the display panel. If this board becomes defective, images won’t display correctly on your Samsung TV’s LCD panel. Repairing this internal T-Con board requires more expertise than simply replacing the panel – something more involved than simple replacement of your Samsung television might entail.
2. Bad Input Port
If your Samsung TV screen is malfunctioning, it could be due to a bad input port. If this is the case, inspect your HDMI cable and T-Con board; if these components are at fault, replacement is necessary.
The T-Con board is an essential component of Samsung TVs’ LCD panels. It helps regulate pixels’ movement and provides audio signal input. If there’s an issue with this component, you could likely experience a black screen on your Samsung TV.
You should inspect the ribbon cable connecting to your T-Con board to identify any contact points that should be blocked. A straightforward fix for this issue is using tape to cover up any exposed contacts.
It may take some effort, but hopefully you can eliminate the lines on your Samsung TV screen. Just keep in mind that if the lines run across the entire display, then there is likely a hardware issue which cannot be rectified.
If the lines are on only one side, you can usually remove them by gently stretching the bezel around the edge of the panel aligned with each line’s end. Doing this will apply additional pressure to keep the ribbon cable in contact with the screen.
Another solution is to take off the back panel of your Samsung TV and inspect its gate drivers, which control horizontal and vertical movement of pixels on the panel. If there are only single-row drivers present, then there’s likely a bonding failure within the panel that needs to be addressed.
If the lines on your screen are more extensive and extend across the entire display, then it could be a hardware issue requiring replacement of the panel. To solve this problem, call an experienced technician for assistance; however, if that’s not feasible, try some DIY fixes first to see if they help solve the issue; however, if these don’t solve it either, replacement of both panels may be necessary.
3. Bad T-Con Board
If you’re noticing horizontal lines on your Samsung TV, the first thing to check is your T-Con Board. This essential component of the television processes all display signals sent to the LCD panel and if it’s malfunctioning, it could result in ghosting images and horizontal stripes across your display.
The T-Con Board is located behind your TV’s back panel and easily identifiable by its ribbon cables running between it and the main board. To clean it out, be sure to reseat all ribbons and use compressed air on them to eliminate dust particles.
Next, unplug any HDMI cables you can locate and reseat them if possible; this may help resolve the problem.
After reconnecting the HDMI cables, try plugging in your television again. It may take around 60 seconds for the display to reset itself again, so be patient.
Once you have a clear view, you can determine if it is the T-Con board at fault for the problem. If so, then replacing the T-Con Board is recommended.
If the T-Con Board isn’t the issue, you may need to look into fixing or replacing the LCD panel. This requires more technical expertise and requires assistance from an electronics expert.
Before you attempt this fix, it is recommended that you unplug your TV from the wall for at least 30 minutes. Doing so will give the capacitors which power the backlight time to recharge.
Furthermore, you should take your TV’s back panel off and place it on a workbench. Make sure there is nothing on the table which could scratch its screen.
Once you remove the screws on the back of your television, open up its back. You should now be able to see three boards: T-Con board, main board and power board.
The T-Con board is the most critical element of your display module. It processes all display signals sent to the panel and outputs them onscreen. If this board becomes damaged, you may experience numerous display issues.
4. Bad Software
If you own a Samsung TV, you may have noticed horizontal lines on its screen. This is an issue common with LCD displays and can be quite frustrating. Before trying to fix these problems, it’s essential to identify what caused the lines and why.
To start solving a line problem on Samsung TV, first determine whether it is hardware or software related. If it is hardware, take your TV to an authorized repair center or contact Samsung directly for assistance.
However, if it’s a software issue, there are some straightforward solutions to take. First and foremost, perform a factory reset on your Samsung TV; this will clear away all files and settings which could be causing horizontal lines on your screen.
Additionally, check to see if your TV’s firmware has been upgraded recently. Older versions of the software may cause horizontal lines on your display.
Firmware updates are an integral part of owning a Samsung TV, and they’re simple to keep up-to-date. By installing the most recent version of your television’s firmware, you can guarantee your screen runs optimally without any glitches.
If your Samsung TV’s firmware has been out-of-date for some time, now is the time to update. If the update cannot be downloaded, a restart of your television may be required in order for the software to install properly.
Although this can be a tedious process, it will ultimately save you time and money in the end. Be sure to follow all instructions carefully as an incorrect update could drastically decrease your device’s performance.
Before updating your TV’s firmware, ensure it is not connected to the internet. Doing this will prevent any bugs from being introduced into the software which could result in issues with your Samsung TV’s display.
Another essential step is to perform a power cycle on your TV. This will reset its operating system, possibly eliminating any bugs causing the lines on the screen.
