What causes your TV screen’s horizontal line?
Four of the most common causes of horizontal lines on a Samsung TV screen is a loose cable connection. power surges or power shortages, electromagnetic interference, and problems with image retention.
Loose cable connection
Over time, the cable that connects your TV to the device it is connected to (such as a cable box, Blu-Ray player, or gaming console) can become loose. When this happens, the signal being transmitted between the two devices becomes disrupted, and horizontal lines can appear on the screen.
- To fix this issue, simply unplug the cables from both the TV and the device it is connected to,
- Check the connections to make sure they are clean and free from any damage,
- And then plug the cables back in securely.
Electromagnetic Interference (EMI)
Electromagnetic interference can cause horizontal lines to appear on the screen if it interferes with the signal being transmitted between the TV and the device it is connected to. This can be caused by electronic devices that are close to the TV, such as cell phones, laptops, or other home appliances.

To reduce the risk of EMI, keeping electronic devices at a safe distance from your TV and avoiding using them near the TV when it is turned on is recommended.
Power surges
Power surges can also cause horizontal lines to appear on the screen. If you have recently experienced a power surge in your home, it may have damaged the TV.

Image retention

Damaged cable

Broken screen
If the horizontal lines are accompanied by cracks or other physical damage to the screen, then the screen itself may be broken and need to be replaced.
Samsung TV, says of the supplier. “They were selling standardized LCD panels as a complete set to many other TV manufacturers, and they did not see any reason why they should do something different for just one model of one client.”
