Solutions to Fix Vertical Lines on Hisense TV Screen
Before reaching out to Hisense customer service for professional assistance, try these basic troubleshooting steps to resolve the issue on your own.
Check the Connections
First, inspect the cable connections on your Hisense TV. Loose or damaged cables might be causing the vertical lines on your screen.
- Unplug all the cables from your TV and plug them back.
- Check whether the cables are damaged and replace them if necessary.
Check the Power Supply
Power fluctuations or an improper power supply can cause flickering lines on your Hisense TV screen.
- Ensure that there are no issues with the power supply.
- Connect your TV to a different power socket to see if this resolves the issue.
Restart Hisense TV
If you’ve been watching TV for an extended period, it may have overheated. Additionally, background apps might introduce bugs that affect your TV’s functionality.
- Unplug your Hisense TV from the power socket.
- Press and hold the physical power button on the TV for about 10 seconds.
- After letting the TV cool down for 3-5 minutes, plug the TV back in and turn it on.
Restarting your Hisense Smart TV can effectively resolve the issue. If the vertical lines persist, proceed to the next solution.
Remove Interference
External devices like streaming devices & boxes, and gaming consoles may cause vertical lines on your Hisense TV screen.
- Unplug these external devices and check if the vertical lines disappear. If they do, the problem lies with the external devices, not your Hisense TV. If it appears, move to the next solution.
Update Hisense TV Firmware
Sometimes, software glitches and outdated firmware can cause vertical lines on your Hisense TV. Update your Hisense TV’s firmware to the latest version to fix these issues easily.
After updating the firmware, check if the issue is resolved. If not, move on to the next fix.
Reset Hisense TV
If the problem persists, hard reset your Hisense TV. The steps may vary by model, but you can use this simple method without a remote:
- Locate the Factory Reset button, which looks like a small hole.
- Take a paper clip, press and hold the Reset button for up to 30 seconds. If nothing changes, press the Reset button multiple times.
- Once the reset process starts, release the button to complete the reset.
Repair T-Con Cable
If resetting your TV doesn’t work, the T-Con board might be damaged. The T-Con board is located behind the screen and under the back panel. You will see vertical lines on the TV screen whenever the ribbon connectors linking the T-Con board and the LCD/OLED panel get loosened. You can fix this issue by yourself. If you aren’t confident enough, you can reach out to Hisense professional support.
- Turn off your TV. Press the power button for around 30 seconds to discharge any power.
- Unscrew the back panel to access the circuit boards.
- Identify the T-Con board by its ribbon cables.
- Use a blower to clean the internal parts carefully.
- Remove the ribbon cable by unlocking it and inspect the connectors for damage.
- Clean the connectors gently. If they are oxidized, consider replacing the T-Con cable with a new one.
- Reassemble your TV and check if the vertical lines are gone.
Block Bad Signal from the T-Con Board
The T-Con cable sends the clock signal through its pins. A damaged pin can cause vertical lines.
Use non-conductive tape to block the signal from the defective pin. Watch the YouTube videos to complete it without any mistakes.
Inspect the Tab Boards on the Panel
Do you notice a single vertical line or multiple pixel-wide lines on your Hisense TV? This issue arises from faulty tab boards that connect the row drivers to the panel.
You cannot manually remove the PCBs attached to the TV panel. However, the tab bond attached to the panel with factory-applied glue may become unstuck.
When the connection drops to a single row of pixels, it fails to receive any data. This problem is often caused by the deterioration of the cleaning products used to clean the TV screen.
Gently tap the bezel of your TV near the lines. If the line fades, it confirms that the tab board is damaged. Contact the professional support service or take your TV to the nearby service center to fix it.
