Although Samsung televisions are known for their reliability, some users may experience issues that impact their viewing experience. One of the most common Samsung plasma TV problems is vertical lines on the screen.
If you’re experiencing this issue, we’re here to help. Read on to learn about vertical shadow lines on your Samsung TV and how to resolve the problem.
What Does It Mean if a Samsung TV Starts Displaying Vertical Lines?
What does it mean when your television is displaying vertical lines? For a Samsung TV, vertical lines on the screen can mean several things.
Typically, the vertical lines are the result of a connection error. The connection of your video input cords, such as HDMI cords, is usually the source. You should check these cords before trying anything else.
Another common cause of vertical lines is software issues. Glitches in your television’s software can cause display problems. A power cycle or factory reset is often enough to fix this problem.
How To Fix a Samsung Plasma TV That Has Vertical Lines?
If you’re asking, “How do I fix vertical screen lines?” the issue is easier to fix than you think! Whether you have a single vertical line on your Samsung TV or horizontal lines on a plasma TV, many fixes are similar. Here are some of the quickest and easiest fixes.
1. Power Cycle the TV
Your first step is to power cycle your television. When dealing with Samsung plasma TV problems like vertical lines, power cycling is the most common fix.
To power cycle, your device, unplug it from its power source. Then, press the power button down for 30-60 seconds. Afterward, plug the television back in and start it as you normally would.
A power cycle drains the television of power to stop all processes. This process functions as a hard reset, rebooting your television and fixing many simple software glitches.
2. Reseat HDMI Connections
A more physical fix is to reseat your HDMI connections. In tech terms, “reseating” is similar to reconnecting or replugging.
Unplug your HDMI cord from both the television and the video source. Plug the cord back into the same port and see if you still have horizontal lines on your plasma TV.
If the issue remains, try a different port. You can also try a different HDMI cord. They’re inexpensive and sold by many retailers.
3. Return Under Warranty
If your television is still under warranty, you can also return the device for a new one. Many retailers will have a warranty system. When buying your television, it’s common to sign up for a warranty toward the end of the process.
Contact the retailer about your warranty. If the television is directly from Samsung, they should hold your warranty. Return or replace the television with this warranty.
4. Remove the Back Panel & Clean the Vents with Compressed Air
If you have a thin black line on your Samsung TV screen, your television may have heating issues. The vents in the back draw in the fresh air and exhaust hot air. If too much dust or detritus clogs these vents, your television may overheat.
Remove the back panel of your television and clean it out with compressed air. You can purchase compressed air from most office store retailers or online.
As a note, make sure you keep your can of compressed air upright. Tilting the can will cause the propellant to spray out. The propellant can damage your more delicate television components.
5. Reseat T-CON Board Ribbons
Another part you can reseat is the T-CON board ribbons. These ribbons are extremely delicate, so ensure you’re handling them carefully.
Your T-CON board is a crucial component. Any fault in the T-CON board can cause issues like the thin black line on your Samsung TV screen. Reseating the T-CON board is a likely fix to the lines on your TV.
6. Block Specific Ribbon Strip Contact Points with a Piece of Tape
The ribbon strip coming in contact with other points may cause the line issue. Block any other contact points with a piece of electronic-safe tape.
7. Contact Samsung Support
If all else fails, you should contact Samsung support. Samsung’s representatives can get you in touch with a technician to fix your television. They can also help you claim a warranty or troubleshoot the issue.
